Just Javascript Five Hundred Card Game Open Misère Tutorial

The 500 card game of yesterday’s Just Javascript Five Hundred Card Game Emoji Entities Tutorial, and incarnation before it, hid from the players the chance to bid …


Open Misère


… but we want to remedy this because …

• it is a fun “out there” addition to the 500 card game
• it can win the game there and then, worth 500 points to that player pairing that lose all ten tricks with the partner of the winning bidder openly displaying their cards to all players, and played by the winning bidder
• the bits and pieces to achieve this programmatically are there …

… but, we are going to take this on gradually, our part one, today, fixing a couple of issues with remote email players using the PHP mail method, those being …

1. add Open Misère successful bidder’s partner’s cards in a second table …
   
if ((!in_bidding || in_kitty) && eval('' + omc) >= 0) {
if (('' + hsuffs[eval(-1 + omc)]).replace('null','').indexOf('<table') != -1 && eval('' + curplayer) != eval('' + omc)) {
outdivhtml=outdivhtml.replace('</table>', '</table><br><p>And here are the cards of the Open player ' + sef(emailsms[eval(-1 + omc)], eval(-1 + omc)) + ' ...</p><br><table' + hsuffs[eval(-1 + omc)].split('<table')[1].split('</table>')[0].replace(/\<tr\ id\=/g, '<tr style=display:none; id=').replace(/SUBMIT/g,'button').replace(/submit/g,'button').replace(/\ href\=/g,' data-href=') + '</table></body>');
} else if (('' + hsuffs[eval(-1 + omc)]).replace('null','').indexOf('<table') != -1) {
outdivhtml=outdivhtml.replace('</table>', '</table><br><p>And here are the cards of the Open player ' + sef(emailsms[eval(-1 + omc)], eval(-1 + omc)) + ' ... ' + zsuffs[eval(-1 + omc)] + '</p></body>');
}
}

   … within the Inline HTML email to other player emails … and …
2. when it is the time for the Open Misère successful bidder’s partner to play their card, their email is BCC’ed to the Open Misère successful bidder’s email address

Feel free to retry the improved 500 card game part of our changed cards_usefocus.html code behind the “Just Javascript” Memories Card Game or live run with single window (good for mobile) or default live run (for your platform, and if non-mobile it will try child popup windows). Try adding “.0” to number of card players to play (our hybrid) “500” card game, and optionally wait or immediately append a comma separated email/SMS address/number list for your “500 card game” players (who can affect the game remotely via email)!

We happened to open up a new email client application to the remote 500 card player emails of yesterday’s Just Javascript Five Hundred Card Game Internationalization Tutorial and, at least for our macOS Mail app, the suit and card emojis came up as gobbledegook in the body Inline HTML section of the the emails.

This discovery, though offputting, also lead, by a few minutes ago (writing this blog post), to a two-pronged improvement to our 500 card game web application as per …

1. the lack of clarity saw us relying (on our non-mobile aspect to viewing) the HTML element title (hover over see blurb) content, and realizing that a full player card list as a title on their name textbox would be just peachy …
   
var wsuffs=[];

function bStringfromCodePoint(jgf) {
var stile='', igf=0;
for (var kgf=0; kgf<spcps.length; kgf++) {
if (('' + spcps[kgf]).split('/')[0] == ('' + jgf)) { igf=kgf; }
}
stile=(('' + spcps[eval('' + igf)]).split('.')[0].slice(-3).substring(0,2).toLowerCase().replace('00','Joker aka ').replace('01','Ace of ').replace('02','2 of ').replace('03','3 of ').replace('04','4 of ').replace('05','5 of ').replace('06','6 of ').replace('07','7 of ').replace('08','8 of ').replace('09','9 of ').replace('10','10 of ').replace('11','Jack of ').replace('12','Queen of ').replace('13','King of ') + ('' + spcps[eval('' + igf)]).split('.')[0].slice(-1).replace('c','Club').replace('d','Diamond').replace('s','Spade').replace('h','Heart').replace('0','No Trump') + 's').toLowerCase();
return stile;
}

// Example call codeline ...
wsuffs[eval(-1 + eval(eval(ixc % nominal_numplayers) + 1))]+=' ' + eval(eval(ixc % nominal_numplayers) + 1) + '.' + Math.floor(eval(ixc + eval('' + nominal_numplayers)) / eval('' + nominal_numplayers)) + ':' + bStringfromCodePoint(eval(spcps[kjn].split('/')[0]));

// Example of use piecing together remote 500 card player email ...
outdivhtml=outdivhtml.replace('</TR>', '<td colspan=' + twentythree + '></td></tr><tr><td colspan=10>500 Card Game Player' + eval('' + bidplayer) + ' Name: <input title="' + wsuffs[eval(-1 + bidplayer)].split('' + bidplayer + '.11')[0] + '" type=text name=myname value="' + pnames[eval(-1 + bidplayer)] + '"></input></td><td colspan=20 style=text-align:center;>... relevant to your cards below ...</td></tr>').replace('</thead>','</THEAD>');

2. the trial of one of the alternative emoji display mechanisms that isn’t String.fromCodePoint([HTML-decimal-entity]) ( ie. &#[HTML-decimal-entity]; ) … eg. Spades ♠ String.fromCodePoint(9824); alternative would be ♠ … had us, amongst a few things, change …
   
function nominalemojisuit(ptrumpsare) {
if (ptrumpsare == 'd') {
return '♦️'; //String.fromCodePoint(9830,65039); // ♦ ️
} else if (ptrumpsare == 'h') {
return '❤️'; //String.fromCodePoint(10084,65039); // ❤ ️
} else if (ptrumpsare == 'c') {
return '♣'; //String.fromCodePoint(9827); // ❤ ️ ❤ ️
} else if (ptrumpsare == 's') {
return '♠'; //String.fromCodePoint(9824); // ❤ ️ ❤ ️
} // 
return '';
}


… all fine and good, now, for macOS Mail app (email client), but, more importantly, it did not break with any of the previously working mail applications, making these changes. Yay!!!!!

… as well as non-mobile users being able to hover over bidding buttons to discover what their team scores with that bid, and the background image text up the top left mentioning “Bid” during any bidding phase and “Click (via email) away …” or “Click (via SMS) away …” for remote players, back for the hoster’s web application window, during the “playing out of the tricks” phase of the 500 card game, hopefully establishing a means by which the hoster can know what is, or is not and should be, going on with the hoster’s 500 card game, and so enabling informed email communication to get the games back on the rails, perhaps.

Previous relevant Just Javascript Five Hundred Card Game Email Tutorial is shown below.

In a blog post some time before yesterday’s Just Javascript Five Hundred Card Game CC Tutorial we talked of “order” when we presented Just Javascript Five Hundred Card Game Order Tutorial. Don’t know about you, but I find the combination of …

• form … and …
• table

… based Inline HTML in an email, asking for interactive input, “orderly”.

Probably we normally think of data to append to an established “table” element via the addition of a new row (“tr” element) or cell (within a row via a “td” or “th” element). Within a “table” element though, you can think of “partitions” in the form of …

• thead … and …
• tbody

… which have that synergy with a webpage’s “head” and “body” elements, the theme of the current blog posting thread being to do away with the need for a “body” element (except for our Inline HTML Emails (which can’t really do anything much without their “body” elements)).

We do a bit of uppercase/lowercase work with the end of “thead” element (ie. </THEAD>) to leave our email Inline HTML “table” “thead” elements blank for …

• 500 card game “bidding” emails … and for …
• 500 card game “kitty/bidding” emails

… but then start to fill in the “thead” element for the “playing out of the tricks” emails, adding today’s work, better card game status information, added to the top of the tabular information presented. Rather than fret about adding to the top, we just slot into the unallocated “thead” slot, for these scenarios, as per …

You may have noticed with yesterday’s work, improvements to the email subject lines during the 500 card game “playing of the tricks” phase, but there are two good reasons to prefer to (additionally) do this in the email body section’s Inline HTML. There, you can …

• change heart and diamond suit emojis to red within … <font color=red></font>
• web browser zooming in combination with a webmail browser based email client can have you zooming in and improving the visibility of the card and suit emojis

Please retry the tweaked 500 card game part of our changed cards_usefocus.html code behind the “Just Javascript” Memories Card Game or live run with single window (good for mobile) or default live run (for your platform, and if non-mobile it will try child popup windows). Try adding “.0” to number of card players to play (our hybrid) “500” card game, and optionally wait or immediately append a comma separated email/SMS address/number list for your “500 card game” players (who can affect the game remotely via email)!

On top of yesterday’s Just Javascript Five Hundred Card Game Names Tutorial “names for numbers” work, today we have two themes to the work …

• shore up that offer on the “500 card game” first Javascript prompt window to enter email/SMS addresses/numbers straight away, meaning no more Javascript prompt windows appear until the end of the game if players follow suit … and …
• should the host of the “500 card game” wait to enter email/SMS addresses/numbers later they can then enter comma separated email/SMS address/number lists which get recognised as any 3 combinations of …
  1. email address (and you can specify a name for those all lowercase PHP mail Inline HTML Email scenarios) and mixed case for mailto: emails for the To: recipient
  2. email address for a CC: recipient (mixed case for mailto: emails)

… to take this first draft of changes to make this naming functionality happen.

We hope you utilize the improved naming functionality with the 500 card game part of Just Javascript Five Hundred Card Game Continuous Scoring Tutorial with our changed cards_usefocus.html code behind the “Just Javascript” Memories Card Game or live run with single window (good for mobile) or default live run (for your platform, and if non-mobile it will try child popup windows). Try adding “.0” to number of card players to play (our hybrid) “500” card game, and optionally wait or immediately append a comma separated email/SMS address/number list for your “500 card game” players (who can affect the game remotely via email)!

Every now and then, and usually involving the timing of a Javascript prompt or confirm or alert popup window, we are caught out by that tiny snippet of time it takes the web browser to complete a rendering task. If that rendering task has not completed ahead of the modal Javascript popup windows it is not always “mission critical” unworkable for the user, as with our current project where we have put up with the annoyance for more than a week now. The scenario of the issue is …


In the 500 card game (with all players non-remote (ie. presumably all using the one device)) on, say, Player 1, clicking their first card, and in the interests of allowing players to only see their own cards, before our fix, the prompt window prompting Player 2 to tell others to turn away because the next prompt window display Player 2 cards, that Player 1 click turn over of card webpage rendering had not finished.


… but better would it be if it was, because then Player 1 involvement would be done and dusted, and would not be a concern going forward with Player 2 activities.

Believe it or not, on occasions all that is needed here to address this annoyance is a fifth of a second of delay, as per …


var passcnt=0;
var gwh='';

function myalertmc(wh) { // new myalertmc() function ...
gwh=wh;
if (passcnt != 0) {
gmyalertmc(); // ... sometimes if okay without delay ...
} else {
setTimeout(gmyalertmc, 200); // ... but sometimes a very short delay is enough time for webpage rendering to complete ...
}
}


function gmyalertmc() { // (wh) ... mainly just the old myalertmc() function ...
var wh='';
if (gwh != '') {
wh=gwh;
gwh='';
}
// Rest of old myalertmc() function code follows, where a Javascript prompt popup window happens ...
}

Up until yesterday’s Just Javascript Five Hundred Card Game Kitty Dropdown Tutorial any “500 card game” web application work was self contained within a single execution of a single web page. But with a 4 player 500 card game, it is usually the case that a game spans several shuffle and deal sets of 10 trick “plays” for a couple of players to reach the 500 or -500 score that determines a winner of that game.

And so it comes to scoring logic today, and a “get arguments” arrangement (via ? and & arguments) to carry on the game …

Previous relevant Just Javascript Five Hundred Card Game Kitty Dropdown Tutorial is shown below.

As mentioned with yesterday’s Just Javascript Five Hundred Card Game Kitty Logic Tutorial, today is an aesthetics day regarding dropdown option colours (not so flexible) and emojis (a tiny bit better). Okay, so the card emojis have no inherent colour, but we had mixed success researching a red diamond (yes) and a red heart (no) suit emoji “redness” solution.

Also, we restricted some bidding button email click options by turning input type=submit into input type=button (ie. no navigation but looks the same) for bids that become too low to be valid in the context of the 500 card game.

Adding to yesterday’s Just Javascript Five Hundred Card Game Remote Kitty Tutorial we’ve concluded …

There’s got to be some logic to what Kitty does?

… surely?!

And so we want to see if there are some aesthetic improvements (and user experience improvements restricting some poor button presses) to the emails, for tomorrow’s work, containing those dropdowns within the …

• remote player kitty logic … and distinct from today’s push to resolve …
• non-remote player kitty logic

… involving that twin bidding/kitty Javascript prompt window ask after three pass answers from bidding players.

Previous relevant Just Javascript Five Hundred Card Game Remote Kitty Tutorial is shown below.

On top of yesterday’s Just Javascript Five Hundred Card Game Kitty Setup Tutorial, today we’ve been concentrating on the scenario of remote email players and the winning bidder working the kitty.

Then, it occurred to us during this, that where we said yesterday …

where you may discern that the trigger to move on is 4 “pass” bids in a row

… that in so doing we were adding an unnecessary ask (perhaps) into the “equation” of how the “500 card game” operates, in that on the third “pass” bid we get back to the last successful bidder anyway, so why not offer them the chance to do either …

• define their kitty swaps (as they won the bidding), and then click on their opening card placement for the first card of the first trick … or, we could not remember exactly the rules, but …
• also allow them to up their own last bid (and then we thought maybe this was feasible, then it opens the door to other players re-entering the “bidding fray” as the opposition argument to thinking this sounds unfair) by clicking a higher ranked bidding submit button

… and this was our main design issue for the day, leaving non-remote scenarios for tomorrow.

And so, if you join us on our “500 card game” (getting towards) non-hybrid journey with our changed cards_usefocus.html code behind the “Just Javascript” Memories Card Game or live run with single window (good for mobile) or default live run (for your platform, and if non-mobile it will try child popup windows), just be aware that a kitty for a non-remote player you swap cards via will not be enacted for a day or so.

Operation “Kitty Hawk” proceeds today on top of the bidding work of yesterday’s Just Javascript Five Hundred Card Game Bidding Tutorial. It’s just that … well … it’s a bit more involved and we only got to the Kitty bit, not the Hawk bit, today.

Tomorrow we should be “taking off” regarding having a kitty (of 3 cards, optionally swappable for others in the winning bidders hand, in a game of 500 played by 4 players).

We’ve plumped for an extra “Kitty” table row be added to a remote email player’s first “playing of cards” email whereby they both …

• make their optional kitty swapping moves via new dropdowns …

  … (whose data navigates with the form (via defined “name” properties), and tomorrow, too, we’ll turn off the card “a” links on kitty scenarios, because we want you to navigate via the email inline HTML form rather than “a” href navigation) … as well as, the usual …
• click for (the first) card to be played (in this first trick)

And so today the navigation out from this is achieved and tomorrow we have to cater for “Kitty Hawk” getting down again …

Hawk … let Kitty down now, that’s a good bird of prey!

Moving on from yesterday’s Just Javascript Five Hundred Card Game Order Tutorial we start out on our “500 card game” bidding phase made up of …

1. pitting the four players against each other for the highest bid in amongst …
   
var bids=["6s","6c","6d","6h","6n","7s","7c","7d","7h","7n","8s","misère","8c","8d","8h","8n","9s","9c","9d","9h","9n","10s","10c","10d","10h","open_misère","10n"];

   … the “open_misère” a job for another day
2. winner of bidding swaps three cards, out, for the three cards of the kitty, in

… and we are concentrating on the first part today. This bidding for the “04.0” scenario still needs to hide cards from other players … doh! As such, it is a whole layer of code (while variable in_bidding is true) on top of a hybrid 500 card game modus operandi.

Previous relevant Just Javascript Five Hundred Card Game Order Tutorial is shown below.

Many humans get comfort from “order”. “Order” means many things to many people. Our recent “colour coding” forays developing our current “500 card game” are our expressions of “order”.

If you actually play 500 with cards dealt to four players (one of them you) in two teams of two it will be interesting to see how each player re-organizes, or not, the ten cards they are dealt. Personally, I break into suit groups and even within those groups I sort (curiously for bridge card game rules, quite often), and later I might try to put right bowers into appropriate rearranged suits depending on what trumps ends up being after the bidding finishes.

We want to do something similar (but no “within suit sorting”), hoping that expression of “order” is a better presentation for our online players too?! The fact that the [playerNumer].[cardNumber]’s become disordered is the price (we have decided) to pay, but we think the users will see how these just represent an expression of a tailored “back of the card” look, and get used to this, but relax a bit with the game as “order” increases.

And so onto yesterday’s Just Javascript Five Hundred Card Game Smaller Deck Tutorial we add to a remote email users presentation the redisplay of data into an HTML table with four rows corresponding to the card suits the players cards fall into.

“In between”, as a phrase, resonates with me regarding computer programming. To me, programming sits between …

• the complexity of human communication and reaction (at the impossible side of the ledger) … and …
• static model (at the “not enough ambition” side of the ledger) of a human scenario you are writing a program (or tool) for

To do better than that “static model” above might rely on user acceptance testing by groups of real humans, hopefully with as much diversity as possible. Perhaps, open feedback, is an alternative way there.

Our “hybrid” “500 card game” functionality has been gradually climbing up the scale above, but to jump to a non-hybrid “500 card game” involving …

• not all cards of deck used
• bidding (but further up the scale would add “betting” (which we will not do, though who knows what is possible with the email and SMS functionalities))
• kitty
• bidding winner leading, rather than Player 1 (nesessarily)
• two opposite hands Vs other two opposite hands
• more nuanced scoring
• misère scenarios (where non-participating player cards might be shown to the rest)
• finesse (during play)

… is quite a big job, and today (after yesterday’s Just Javascript Five Hundred Card Game Follow Suit Colour Coding Tutorial) we creep onto the big job from that “display affecting” “not all cards of deck used” small job. How first to allow the host specify thet the “500 card game” is non-hybrid …

The smaller deck coding biggest step? Redefining the “spcps” and “cards” arrays, when we detect a “04.0” scenario above, cutting out 2’s and 3’s and red 4’s, is the start you then code around with a “suck it and see” (approach) aided by a web browser web inspector, is how we approached the start of our long journey.

Previous relevant Just Javascript Five Hundred Card Game Follow Suit Colour Coding Tutorial is shown below.

Onto yesterday’s Just Javascript Five Hundred Card Game Follow Suit Tutorial as far as remote email players of the hybrid “500 card game” go we come at improving the user experience, today, from two different colour coding ideas …

• within the inline HTML email sent to remote “500 card game” players start colouring heart and diamond card emojis red via …
  
<font color=red>&#[heartOrDiamondEmojiCodePoint];</font>

• within the inline HTML email sent to remote “500 card game” players start colour coding the buttons preceding the card emojis into five categories as per …
  1. lightgreen background if the same suit as the current trick’s lead card
  2. lightgreen background with yellow border if the same suit as the trick lead card, and is trumps
  3. yellow background if card suit is trumps
  4. normal background for otherwise clickable cards dealt out to current user
  5. missing card emoji if that card already played in this “500 card game” incarnation

… encouraging the following of suit for such remote users, and adding that clarity to help avoid some confusion playing the game (as a remote user sees none of the context the host or dealer of the “500 card game” sees), and keeping it flowing without the host and dealer doling out any “did not follow suit” return email warnings that hold up the game.

All this colour coding is appearing within the (inline HTML) body section of the email. The subject section relies on the inherent colour of the emoji card, and that, up to this point of time, even for hearts and diamonds, is black.

So, yet again, to see these nuances in action try hosting a (hybrid) “500 card game” of your own with our changed cards_usefocus.html code behind the “Just Javascript” Memories Card Game or live run with single window (good for mobile) or default live run (for your platform, and if non-mobile it will try child popup windows). Try adding “.0” to number of card players to play (our hybrid) “500” card game, and optionally wait or immediately append a comma separated email/SMS address/number list for your “500 card game” players (who can affect the game remotely via email)!

For today’s work progressing yesterday’s Just Javascript Five Hundred Card Game Host Aesthetics Tutorial we had as an email to oneself …

Fwd: Click away wider, documenttitle global variable, Know when 500 game ends, and add hybrid 500 card game in document.title

… the incidentals for today on top of the planned “enforcing follow suit” work from a few days ago.

Writing “chores” down ahead of a day is, of course, highly recommended, as the brain can mull over it with sleep. Not always possible, of course, but good.

The “documenttitle global variable” may amuse or look kludgy to you, but we like the idea of fundamental DOM members such as …

• document.URL
• document.title
• location.href

… that deserve coding for more than one incarnation “meaning” (perhaps only discovered as a project matures) can be accommodated well (via “function documenttitleeq” below) working the logic using Javascript global variables as per …

1. we went around globally substituting any “document.title=[blah];” code with “documenttitleeq([blah];” code then globally substituted any remaining “document.title” with “documenttitle” then fixed up any “documenttitleeq([blah];” code with “documenttitleeq([blah]);” code … then …
2. 
var documenttitle=document.title; // up the top as the global variable initialization

function documenttitleeq(indt) {
documenttitle=indt;
if (card_game == '500ish') {
document.title='500 (hybrid) card game ... ' + scoresuffix;
if (eval('' + nominal_numplayers + ' * (' + scoresuffix.replace(/\,/g, ' + ') + ')') >= Math.abs(eval('' + totcpp))) {
if (eval('' + totcpp) > 0) {
totcpp=-totcpp;
if (confirm('Thanks for playing the 500 (hybrid) card game ... ' + scoresuffix + ' ... OK to play again?')) {
location.href=document.URL;
}
}
}
} else {
document.title=documenttitle;
}
}


As you see, this helps us with this (hybrid) “500 card game” that somebody not in the game going to look at the host or dealer Player 1’s webpage now has a mechanism to discover what they are playing without having to interfere with that game (designed as a “Just Javascript” (ie. “No Body Definition”) project).

Regarding the enforcement of “following of suit”, sure, it’s an important part of a real game of 500 where four players play and they are in teams of two, but we’re not doing that, yet, with our hybrid 500 card game, and so allow this “hybrid” at least have some variety on this front, as per …

Previous relevant Just Javascript Five Hundred Card Game Host Aesthetics Tutorial is shown below.

On top of the progress of yesterday’s Just Javascript Five Hundred Card Game Email Buttons Tutorial, today, we’ve been trying to improve …

• aesthetics of the host (hybrid) “500 card game” … and in so doing …
• improve the “user experience” playing that “500 card game”

We worked on the SVG content to the background images so as to make the cards be …

• more legible (via increased size and appropriate repositioning and change to Verdana font family)
• colour coded … hearts and diamonds red (via “stroke:red;”) and clubs and spades black (via “fill:black;”)

Yesterday’s Just Javascript Five Hundred Card Game By Correspondence Tutorial “500 card game” communication options felt …

• more like “sharing” … and only mildly …
• anything like “collaboration”

… and we think that by allowing (submit) button presses with the “email via PHP mail” conduit to affect the “500 card game” display seen by the dealer and hoster (ie. Player 1) is more your “collaboration” integration, wouldn’t you say?

Well, it’s possible in two senses …

• inline HTML email allows forms with multiple “submit” buttons allowed … as well as …
• PHP helper integration to control the existence or not of some web server file(s) … as our research into postMessage ideas got us to realize its brilliance is not enough for what we are after

Still “Just Javascript” (ie. “No Body Defined”) back at the parent (here with all this), though it constructs emails that can contain a body element in order to navigate via an inline HTML form to “be a player” remotely.

Previous relevant Just Javascript Five Hundred Card Game Joker Tutorial is shown below.

Yesterday’s lack of a Joker in the “500” card game established yesterday with Just Javascript Five Hundred Card Game Tutorial has been remedied.

And we forgot the logic that allows a lead up player to still win (that trick) with a paltry non-trump card if the other users also play cards that are not trumps nor a larger card of that same leading suit, nor the Joker.

There’s still a bit more logic to go about the play (ie. enforce the following of suits), then aesthetics and then “user experience” and finally sharing, perhaps.

But see how you go with the changed cards_usefocus.html code behind the “Just Javascript” Memories Card Game or live run with single window (good for mobile) or default live run (for your platform, and if non-mobile it will try child popup windows).

Previous relevant Just Javascript Memories SVG Emoji CSS Animation Tutorial is shown below.

There are lots of styles of animation that do not suit a “Just Javascript” (ie. “No Body Definition”) style of web application as for Just Javascript Memories SVG Emoji Background Tutorial‘s work, but there is one left that can really help add some excitement and colour to the whole project, that being the use of CSS @keyframes Animation techniques.

You’d be amazed how widespread it is regarding the CSS property animation availability we found at Animatable CSS properties, thanks, from colour through aesthetics to positioning and sizing of webpage content.

We decided the way we’d apply some animation was to, between the first and second selection of cards in the Memories game, for any user, we’d add a bit of tension by some mild animated movement applied to the multiple background images. Yes, animations can happen for multiple background images, even variable amounts of change for each single background image part, if you like, but we applied the same movement to every part of the background image components.

We also animated some aesthetics via some CSS filter application, as per …


if (nominal_numplayers) {
defstyle=defstyle.replace('} </style>', ' animation: animatedBackground 10s linear infinite; } @keyframes animatedBackground { from { filter: contrast(175%) brightness(120%) saturate(70%); } to { filter: contrast(95%) brightness(90%) saturate(150%); } } </style>');
}


… that can be built upon by a possible second layer of animation (and plain straight background colour randomness) via the document.head.innerHTML+=bpmore(defstyle); use of …


function bpmore(incss) {
var cgcols=['lime','maroon','lightblue','purple','navy','teal','fuchsia','olive','red','lightgreen','darkorange','pink','orange','yellow'];
var icg=eval(0 + Math.floor(Math.random() * cgcols.length));
var mvt=eval(10 + Math.floor(Math.random() * 40));
var kf=" @keyframes animatedBpos { from { background-position: bp1; } to { background-position: bp2; } } ";
var inkf="", jnkf="", jnkfd="", nn=0;
var inks=[];
if (incss.indexOf('} </style>') != -1) {
if (incss.indexOf('background-position:') != -1) {
inkf=incss.split('background-position:')[1].split(';')[0].trim();
inks=inkf.split(',');
for (nn=0; nn<inks.length; nn++) {
if (('' + inks[nn]).indexOf(' ') != -1) {
if (('' + inks[nn]).indexOf('px') != -1) {
jnkf+=jnkfd + eval(mvt + eval('' + inks[nn].replace(/px/g,'').replace(/\%/g,'').split(' ')[0])) + 'px ' + eval(30 + eval('' + inks[nn].replace(/px/g,'').replace(/\%/g,'').split(' ')[1])) + 'px';

}
} else {

}
jnkfd=',';
}
if (incss.indexOf('} @keyframes ') != -1) {
return incss.replace('yellow',cgcols[icg]).replace('} @keyframes ', ' animation: animatedBpos 10s linear infinite; }' + kf.replace('bp1', inkf).replace('bp2', jnkf) + ' @keyframes ');

Previous relevant Just Javascript Memories SVG Emoji Cursor Tutorial is shown below.

The “Memories” functionality introduced in yesterday’s Just Javascript Memories Card Game Tutorial is a game component, and it is good to remember the “game” side to that. If a web application is a game and the player is not being timed, they may feel that freedom to be multitasking, go and do something else, and then come back “to work the game”. In that scenario, it would be quite friendly to offer a mechanism by which to remind the player(s) of the status of the game as they left it.

Even though we are in “Just Javascript” (ie. “No Body Definition”) mode of use here, we still have CSS to offer a solution here, and we’ve chosen in the CSS woooooorrrrrllllllddd to research a curiosity we’ve had “for just about ever”. Can we tailor the webpage “cursor” to be “emoji text content”. We’ve looked this up in the past, and did not succeed on that occasion with the “url([SVGcontent])” we thought might be the go. It was tweaking onto this great link that gave examples for us to succeed this time, thanks, using code such as …


csuff='';
var hjg='' + curplayer;
for (var ipl=0; ipl<hjg.length; ipl++) {
csuff+=String.fromCodePoint(eval(8320 + eval(eval('' + hjg.substring(ipl,eval(1 + eval('' + ipl))).charCodeAt(0)) - 48)));
}
if (ocp) { ocp.style.cursor='url("data:image/svg+xml;utf8,<svg xmlns=' + "'" + 'HTTP://www.w3.org/2000/svg' + "'" + ' width=' + "'" + '96' + "'" + ' height=' + "'" + '48' + "'" + ' viewport=' + "'" + '0 0 100 100' + "'" + ' style=' + "'" + 'border-radius:60px;background-color:rgba(255,0,0,0.1);fill:black;font-size:24px;' + "'" + '><text y=' + "'" + '50%' + "'" + '>' + String.fromCodePoint(10067,10068) + csuff + '</text></svg>") 16 0, pointer'; }


… that “ocp” being the “evt.target” of the “onlick” event logics previously talked about. Notice the fallback to those set cursors of “the cursor wooooorrrrrllllllddd”.

Along the way we offer variations to the playing rules of Memories, too, to add some variety for the user(s).

nominal_implication=" var prompt = function(zwords, defwords){ return null; }; ";
fiftytwo=-1;
backi="/Games/Memories/Memories.jpg";
} else {
nominal_numplayers=null;
}
}


… “prompt” is overridden as above. That, and overriding the scoring mechanisms, and this same codeset is nearly there towards accommodating our new quite different requirement.

But with “No Body Definition”/”Just Javascript” how can we show and implement this new Memories Card Game usage? It’s a two way integration, the easier one being …

• offer a place for click/touch on the default background imagery … and with that webpage reminder …
• what is an independent “add on” event methodology available to us, so as not to interfere with event logic that has preceded? … spoiler alert … double click …
  
ele.addEventListener('dblclick', function(evt) {
location.href=document.URL.split('?')[0].split('#')[0] + '?card_memories=y';
});

  … (or two clicks quickly in a row) … as per …
  
var lastec='', notyet=false;


function antilastec() {
lastec='';
}


function antinotyet() {
notyet=true;
}

ele.addEventListener('click', function(evt) {
if (evt.touches) {
if (evt.touches[0].pageX) {
iourx = evt.touches[0].pageX;
ioury = evt.touches[0].pageY;
} else {
iourx = evt.touches[0].clientX;
ioury = evt.touches[0].clientY;
}
//alert('' + iourx);
} else if (evt.clientX) {
iourx = evt.clientX; // - elemLeft;
ioury = evt.clientY; // - elemLeft;
} else if (!evt.touches) {
iourx = evt.pageX; // - elemLeft;
ioury = evt.pageX; // - elemLeft;
}
if (('' + iourx + ',' + ioury) == lastec && lastec != '' && notyet) {
location.href=document.URL.split('?')[0].split('#')[0] + '?card_memories=y';
} else if (lastec == '') {
setTimeout(antilastec, 2000);
setTimeout(antinotyet, 200);
notyet=false;
lastec='' + iourx + ',' + ioury;
} else {
setTimeout(antilastec, 2000);
setTimeout(antinotyet, 200);
notyet=false;
lastec='' + iourx + ',' + ioury;
}
clickedmaybe();
});


Again, feel free to try this in the changed cards_usefocus.html code behind the “Just Javascript” Memories Card Game or live run with single window (good for mobile) or default live run (for your platform, and if non-mobile it will try child popup windows).

Previous relevant Just Javascript Card Order Game One Window Tutorial is shown below.

The “one window” rather than (52 + 1) = 53 windows scenario set up as a possibility with yesterday’s Just Javascript Card Order Game Mobile Tutorial had us wondering …

… a one window solution that saves the day for mobile and we see as a good candidate for “default-ness” for non-mobile … we’ll let that one sink in for a day or so?!

… and tomorrow is today. We’ve decided not to make the one window scenario the default for non-mobile platforms, but serve as a fallback for some of the scenarios mentioned below …

• the user gets blocked from using the popup windows on their non-mobile platform web browser … big possibility!
• the user clicks half way through the popup window incarnation the parent window … all the child popups disappear behind … annoying … so …
  
var flexible=false;

function secsu() {
var ewd;
if (secs == 0) {
if (document.URL.indexOf('onewindow=') != -1 || navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile/i)) {
flexible=false;
} else {
flexible=true;
console.log('Flexible=T');
}
setTimeout(blater, 2500);
}
if (eval('' + overallgoes) < 52) {
secs++;
} else if (document.title.indexOf('Congratulations') == -1) {
document.title+=' ... Congratulations! End of Game! Refresh webpage to try again.';
}
var decs=document.title.split('.');
if (eval('' + decs.length) >= 3) {
document.title=document.title.replace('.' + decs[2].split(' ')[0] + ' ', '.' + secs + ' ');
} else {
ps=document.title.split('/')[0].trim();
pg=document.title.split('/')[1].split(' ')[0];
if (ps.indexOf('.') == -1 || pg.indexOf('.') == -1) {
ps=eval('' + overallscore + '.' + psecs); //eval(document.title.split('/')[0].trim());
pg=eval('' + overallgoes + '.' + secs);
document.title=document.title.replace(document.title.split(' ')[0], '' + overallscore + '.' + psecs + '/' + '' + overallgoes + '.' + secs);
//console.log('document.title becomes ' + document.title);
} else {
ps=eval(ps);
pg=eval(pg);
}
}


if (flexible) {
if (document.hasFocus()) {
flexible=false;
console.log('Flexible=F');
lastzkq='';
lastzkl='';
owidth=oowidth;
oheight=ooheight;
for (var igh=0; igh<oplist.length; igh++) {
opltlistl[igh]=oopltlistl[igh];
opltlistt[igh]=oopltlistt[igh];
if (oplist[igh]) {
console.log('Flexible=F' + igh);
if (!oplist[igh].closed) {
try {
oplist[igh].close();
oplist[igh]=null;
} catch(ewd) {
}
} else {
oplist[igh]=null;
}
}
}
}
}
}


… document.hasFocus() to the rescue again … the multiple background images of yesterday’s work being a default part of any incarnation, and whether the click event logic of yesterday becomes relevant depends on …

• if user is a mobile platform user, always relevant
• user enters URL with argument like ?onewindow=y then is always relevant … else …
• a scenario as above means that from that point on, the multiple background image one window click on cards modus operandi becomes relevant

We improve the web browser conditions too, if a non-mobile user “clicks half way through the popup window incarnation the parent window” in that we programmatically close any open child popup windows! Phew!

Feel free to try this in the changed cards_usefocus.html code behind the “Just Javascript” live run with single window (good for mobile) or default live run (for your platform, and if non-mobile it will try child popup windows).

Previous relevant Just Javascript Card Order Game Mobile Tutorial is shown below.

Yesterday’s Just Javascript Card Order Game Tutorial mobile usage scenario was impractical, in that mobile platforms can not work popup windows in front of a parent window. Can we convert those non-mobile popup windows into … well … what exactly?

Well, in order to keep to our “Just Javascript” (ie. “No Body Definition”) pledge with this project, we needed to simulate those popups as background image parts, in the sense that you can have multiple background images these days with your HTML. Even with html as your CSS styling selector … it pans out … we needed to prove that today.

Also, today, for the first time, we achieved via …

1. comma separated background-repeat: no-repeat; list
2. comma separated background-size list (set popup width height list until last one bigger (based on screen.width screen.height) for the parent background image (no-repeat))
3. comma separated background-position list (as per what window.open in non-mobile was using for left top until last one’s 0px 0px)
4. comma separated background-image list (as per what window.open in non-mobile was using for URL([imageURL]) until last one’s linear-gradient(rgba(255,255,255,0.4),rgba(255,255,255,0.4)), url(//www.rjmprogramming.com.au/rjmquiz_plus.jpg))

… as per (the previous “window.open” becomes “windowopen”) …


function windowopen(one, two, three) {
if (document.URL.indexOf('onewindow=') != -1 || navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile/i)) {
console.log('Here ' + kq);
opltlistl.push((three.split('left=')[1].split(',')[0].split(')')[0].split('.')[0] + '.' + one.split('spcp=')[1].split('&')[0]));
opltlistt.push((three.split('top=')[1].split(',')[0].split(')')[0].split('.')[0] + '.' + kq));
owidth=eval(three.split('width=')[1].split(',')[0].split(')')[0].split('.')[0]);
oheight=eval(three.split('width=')[1].split(',')[0].split(')')[0].split('.')[0]);

Previous relevant Just Javascript Card Order Game Tutorial is shown below.

Today we’ve made the web application of yesterday’s Just Javascript Quiz Drag Tutorial “dual purpose” …

• quiz … as for yesterday, and before … and as of today, making more use of the card organizational side to the popup windows we introduce …
• card order game

This card order game asks you to force the focus of the correct popup window (to score in the Card Order Game) in the order as designated by the background image part we have added today, and supported by the following Javascript “mapping” code …

Previous relevant Just Javascript Quiz Drag Tutorial is shown below.

Adding to yesterday’s Just Javascript Quiz CSS Styling Tutorial we have added some …

• non-mobile platform, only …
• drag and drop functionality … for …
• the child popup windows

… achieved through the comparison of …

• original [popupWindow].screenLeft and [popupWindow].screenTop … initially, to …
• [popupWindow].screenLeft and [popupWindow].screenTop over time

… and if one popup is dragged to overlay another it is closed, or you, as the user, can just drag and drop for clarity, leaving the popup window of the next quiz question out in the open, perhaps.

In order to achieve this, and keep backward compatibility we needed to delay the quiz question prompt window via …

1. document.hasFocus() is true … then if …
2. inhouse dragging checks clear it of overlaying another popup (in which case that popup is programmatically closed, allowing another popup to become the “focus window”) … then …
3. delay (by 8 seconds) the prompt window (and in that time the user can be dragging popups (but no popups were harmed in the making of this tutorial)) … via …
   
setTimeout(function() { hj=prompt(dp + window.opener.blurb(), def); if (hj == null) { hj=''; } else { hj=window.opener.assess(hj); } if (hj.replace(def,'') != '') { checka(hj); } else { setTimeout(pa,10000); } aminmiddle=false; }, 8000);

Still “No Body Definition”, “Just Javascript”!

Previous relevant Just Javascript Quiz CSS Styling Tutorial is shown below.

Our “Just Javascript” adage used throughout this blog posting thread, up until today, headed by yesterday’s Just Javascript Quiz Content Management Tutorial needs more explanation. Really what we are trying to do might better be described as “No Body Definition” (ie. no defined document.body) but have …

1. an HTML webpage (ie. within <html> and </html>) … has …
2. <head> and </head> (ie. document.head) content which can be made up of (at least) title, style, script, link, meta tags

To assert “Just Javascript” is just to allow script content above, but what we should really say is “Just Head Content” but that is not nearly so marketable, is it now?!

The thing is, though, we can dynamically add title, style, link, meta tag content within the script content, and we do this more than statically define it, to feel better about our ethics saying “Just Javascript”.

Dynamically adding style CSS styling either …

• using Javascript DOM (not available to us for document.getElementById([elementID] and nor can we use inline CSS via style=”[CSSstyling]” statically within HTML element code for that same reason) ideas today though … remember “No Body Definition” … but …
• we can append to <head> and </head> (for today’s scenario) as per …
  
document.head.innerHTML+="<style> html { background-color: yellow; font-size: 36px; background: URL('//www.rjmprogramming.com.au/rjmquiz.jpg'); background-size: cover; } </style>";


… allowing (into the scope of our work CSS styling of) background (image(s)) and other background styling ideas that can get us past the anonymous feel the web application had before today. We tailored the background image above to suit our Quiz and help it be a bit more self explanatory … thanks CSS styling! We add onto the child “card” popup windows, their own background image colour and pizazz, to cheer things up in CSS styling enhanced cards_usefocus.html code behind the “Just Javascript” live run.

You may well ask …

What can we hang our hat on with CSS style selectors without a body element?

Well, we had to step out of our usual comfort zone of CSS styling thinking, and realize, even without that body element we can still use the html selector to “point at” the entirety of your webpage of interest.

It feels like an “onions of the 4th dimension” idea to allow the user to control the questions and answers behind the workings of yesterday’s Just Javascript Quiz Multiple Users Tutorial‘s web application, featuring “Just Javascript”.

It’s not “Just Javascript” we’re keeping, it’s “Just HTML” client work rather than involving any serverside anything (eg.PHP) and yet this question and answer data could be quite sizeable. What can we use, given no PHP serverside, and given we’ve decided not to navigate via Ajax/FormData techniques? How about “the better than HTTP Cookies” twins …

• sessionStorage … and …
• localStorage

Yep, set up a means by which these two can store and restore questions and answers entered by the user, using these storage methods above.

Previous relevant Just Javascript Quiz Multiple Users Tutorial is shown below.

Adding to yesterday’s Just Javascript Quiz via Cards Tutorial we were surprised how difficult it was to stay with “Just Javascript” and allow for multiple player play.

We didn’t opt for the parent to ask about the number of players, curiously, but on the second quiz answer and on, offered any non first player the chance to identify themselves as a new player into the game by appending their answer with a space character.

The implication of that is that we’ll want to run Javascript functions of the parent from the children as per …


oplist[eval(-1 + oplist.length)].document.write("<link rel=icon href=" + cards[kl] + "><scr" + "ipt type='text/javascript'> var da='" + eval(0 + kq) + "'; var dp='Given answer is integer from 0 to 25 ... " + sq[kq] + "'; var def=String.fromCodePoint(" + spcps[eval('' + kl)].split('/')[0] + "); function checka(tpa) { var os=''; var ps=eval(window.opener.document.title.split('/')[0].trim()); var pg=eval(window.opener.document.title.split('/')[1].split(' ')[0]); if (tpa.trim() == da) { ps++; os=tpa.split(da)[1]; } else { pg++; os=tpa.split(tpa.trim())[1]; } window.opener.document.title=ps + os + '/' + pg + ' is User Score/Goes'; window.close(); } function pa() { if (document.hasFocus()) { var hj=prompt(dp + window.opener.blurb(), def); if (hj == null) { hj=''; } if (hj.replace(def,'') == '') { setTimeout(pa,1000); } else { checka(hj); } } else { setTimeout(pa,1000); } } pa(); </scr" + "ipt>");


… accessing …


function blurb() { // theblurb and wblurb are global variables changed elsewhere
if (wblurb == ' Hello Player 1' && theblurb == ' If you are player 2 rather than player 1 append space to your answer.') {
theblurb='';
wblurb='';
}
return theblurb + wblurb;
}


… giving the rather curious behaviour whereby a Javascript prompt window can be dynamically different from one document.hasFocus() incarnation (ie. the user might go away and answer another “card” Number Quiz question) to another (even not attending to answering the Javascript prompt window) … huh?!

The significantly changed cards_usefocus.html code behind the “Just Javascript” live run is worth a look, we figure, for up to 52 players who play in turn.

Previous relevant Just Javascript Quiz via Cards Tutorial is shown below.

Yesterday’s Just Javascript Navigation Tutorial continues our interest in “Just Javascript” (or “No Body”) web applications.

We think today’s “Numbers Quiz” via a “Card Deck” organizational design ups the ante on all this. We realize now what we have been missing not having involved document.hasFocus() in any of our popup window scenarios. Today, at least on non-mobile, we involve 52 such popup windows each containing a “Number Quiz” question presented as a Javascript prompt (sub-)window. This would not be feasible without document.hasFocus() as you can tell if you examine the cards_usefocus.html code behind the “Just Javascript” live run best used on your non-mobile platforms where popup windows can sit in front of parent (and beside sibling) windows, whereas mobile platforms open new web browser tabs for all the 52 windows of (a card deck) design.

Look out, too, in the code above, for use of window.opener back reference from a popup window back to the parent window where the scoring data is held, and updated by each popup window because of that window.opener avaalability.

The recent use we made of …

As such, today we present the very simple (but first time use of the interesting hasFocus) “proof of concept” …

<script type='text/javascript'>
function dothis() {
var ais=null;
var urlis=' ';
while (urlis != '') {

urlis=prompt('Enter URL that we will send you to (exit to stop)', '');
} else {
setTimeout(dothis, 2000); // urlis=' ';
return;
}
if (urlis == null) { urlis=''; }
if (urlis.toLowerCase() == 'exit') { return; }


if (urlis.trim() != '') {
if (urlis.substring(0,1) == '.') { // relative URL
urlis=document.URL.split('nobody.htm')[0] + urlis;
} else if (urlis.substring(0,1) == '/' && urlis.indexOf('//') == -1) { // relative URL
urlis=document.URL.split('//')[0] + '//' + document.URL.split('//')[1].split('/')[0] + '/' + urlis;
} else if (urlis.split('/')[0].indexOf('.') != -1) { // absolute URL
if (urlis.toLowerCase().indexOf('http') != 0) {
if (urlis.indexOf('//') == 0) {
urlis=document.URL.split('//')[0] + urlis;
} else {
urlis=document.URL.split('//')[0] + '//' + urlis;
}
}
} else { // relative URL
urlis=document.URL.split('nobody.htm')[0] + urlis;
}
ais=document.createElement('a');
ais.onclick=function() { window.open(urlis, '_blank', 'top=100,left=100,width=600,height=600'); };
if (1 == 2) { ais.href=urlis; }
ais.target='_blank';
ais.click();

Previous relevant Just Javascript Webmail No Body Attachment Tutorial is shown below.

A “hard liner” for the proper use of “business emails” could argue that an email without an attachment is not productive. Couldn’t you just have a face to face meeting instead, if there is just wording in the email (as we somewhat concur with, as an argument)? So yesterday’s Just Javascript Webmail No Body Tutorial had that limitation of no email attachment logic, which we remedy today.

And this is where PHP’s wonderful file_get_contents (function) means by which we garner (URL) content …

• definitely works with “relative URLs” relative to HTTP://www.rjmprogramming.com.au/HTMLCSS/ where today’s unchanged webmail_nobody.html resides … in “parsing parlance” …
  
"relative (URL)" to the left of any # or ? of what lies to the left of the most right hand "/" (of what the address bar URL is of the webpage you are on)

  … so that …
  1. “relative URLs” starting with “./” (followed by the filename, or just the filename (as you can see us using in today’s tutorial picture)) refer to the web server directory corresponding to “HTTP://www.rjmprogramming.com.au/HTMLCSS/” … whereas, for example …
  2. “relative URLs” starting with “../” (followed by the filename) refer to the web server directory corresponding to “HTTP://www.rjmprogramming.com.au/” … for example

  … and …

• might work for “absolute URLs” (those that start with https: or HTTP: or even // (that we beg you not to confuse with Windows UNC pathnames) that infer a transport protocol of the transport protocol (out of https: or HTTP: or even file:) that got you to the webpage you are currently on), the “might” being far more likely on “absolute URLs” pointing to the same domain as indicated on the URL of the address bar of the webpage you are currently on

Upshot is, the user in their email Body section definitions (still no HTML body though!), can throw into any word they use, an “absolute URL” of interest, or a “relative URL” of interest, of files they want to attach (as attachments, doh!) in their email.

Depending on the email rules though, there are limits as to the amount of attachment data allowed. We’ll leave that to you intrepid “explorers of the Net” to discover for yourselves. On this subject though, have you noticed that with the Photos (or Gallery) app Share options, the Email option drops off when you have highlighted a large number of photos or videos or audios to share? That’s that email limit coming into play.

So feel free to try this HTML-body-less web application live run to see what we mean here. Though the parent HTML is unchanged today, the new (email) attachment functionality needed a changed PHP emailhtml.php to make this happen.

Did you know?

This (relative URL) “../” navigation backwards up the hierarchy of the web server directories will, if repeated (ie. nested to “../../” etcetera) too many times, get you into uncharted unnavigable (web server directory) places relative to that web server web site’s Document Root (below which you can not access in public webpages, normally). But when you perform similar thinking with “absolute URLs” and go “HTTP://www.rjmprogramming.com.au/HTMLCSS/../../../blahdeblah.jpg” (in a web browser address bar) for instance, you cannot get into trouble, as you just don’t get beyond this sending you to (attempt the reference to) “HTTP://www.rjmprogramming.com.au/blahdeblah.jpg” because on this rjmprogramming.com.au Apache domain the correspondence of the Document Root (web server directory) is to “HTTP://www.rjmprogramming.com.au/” as the place you are not allowed (and cannot) go below in the hierarchy tree.

Were you around and interested in our series of about three blog postings in the series on the theme of creating webpage functionality of some interest, involving no Javascript, when we presented Missing Javascript Audio on Unmute Tutorial? Well, today, it’s the turn of “just Javascript”, which is sort of like what Bookmarklets were about.

With today’s “just Javascript” we have to qualify that a little for our webmail emailing sender application with the architecture …

• parent webpage with only document.head and apart from a document.title just a script Javascript tag of content (using Javascript prompt windows to ask for user information) …
• sending (POSTing) data via …
  1. Ajax XMLHttpRequest object … as the conduit for …
  2. FormData object

  … to our changed …

• PHP communication emailing tool emailhtml.php … and out to …
• the emailee (out there in the big wide woooorrrrrllllldddd)

Guess we find it interesting that you can do all this (sending of email to emailee recipients) with no document.body in sight.

• On non mobile platforms you can set up the playing of “audio” data via the use of an HTML audio tag with the properties …
  1. controls
  2. autostart
  3. loop
  4. muted

  Above is all fine and good for non-mobile but not so good for mobile, so to keep all happy with the one click, still, is to transfer HTML coding from …

  
<audio id='myaudio' title='Got a sock in my mouth, so you might want to unmute me!' type='audio/mp3' style="display:none;margin-left:-350px;opacity:0.1;" autostart muted loop controls src="Puppy-sounds.mp3" />


  … to …

  
<!--audio id='myaudio' title='Got a sock in my mouth, so you might want to unmute me!' type='audio/mp3' style="display:none;margin-left:-350px;opacity:0.1;" autostart muted loop controls src="Puppy-sounds.mp3" /-->
<audio id='myaudiotwo' title='Got a sock in my mouth, so you might want to unmute me!' type='audio/mp3' style="margin-left:-350px;opacity:0.1;" autostart="0" loop controls src="Puppy-sounds.mp3" />


  … and a src= URL data source (as we thank this link for today), or data URI if preferred (which we do for today’s image data from this link, thanks (when we were researching animated GIF data URIs (which we may return to at a later date))

… that sets up the scenario that all the user has to do to hear the audio is to click the “muted” control button, without needing the usual Javascript play() methods … but not on mobile!

Feel free to let the puppy play, that uses the HTML and CSS (but no Javascript) of the_nested.html and based largely on the previous HTML Nested Centering via Multiple Select Tutorial so that these changes reflect how we got to the first draft of today’s work. Maybe some of the ideas are of interest. We hope so!
