Feedback Inline HTML Form Email Collaboration Reply Tutorial

Yesterday’s Feedback Inline HTML Form Email Collaboration Tutorial start has been continued, and we were surprised how hard it was replying to that first Inline HTML Email to another Inline HTML Email and swapping the emailee To with the emailee From, but there you go. Sometimes it is hard to tell what will be difficult and what not.

And even with this “reply to first collaboration call email” now set up to chain the emailing collaboration text between the two collaborators, we find some mysteries we’ll keep you posted on. The most intriguing is the Inline HTML Email form behaviour for textarea elements only accepting space characters when you paste them in, but not typing them in. Go figure! It’s probably something on our end, but have never seen this before. Work for tomorrow.

Have a look, anyway, at …

The supervisory lightly changed feedback.htm‘s live run link … supervises …
a supervised and extensively changed emoticon_keyboard_shortcuts.php … which calls on …
a further supervised lightly changed emailhtml.php

Let’s face it. It’s a work in progress!

Feedback Inline HTML Form Email Collaboration Tutorial

We want to embark on a more collaborative phase to our Feedback web application last tweaked with the recent Feedback SMS via Highlighting Mark Tag Tutorial.

What’s changed here (at RJM Programming recently) to make this something we have mulled over in our mind, and imagined, is our PHP mail techniques to send Inline HTML Form Emails. So this means, now …

our changed feedback.htm‘s live run has a new “Send Feedback as Inline HTML Email” button … that sends a new …
HTML …
document.getElementById('tdhuhta').innerHTML='<body><h1>Feedback and Collaboration to ' + vstvs + '</h1><br><h3>RJM Programming<h3><br><br><form method=POST action="' + document.URL.split('HTMLCSS/feedback.htm')[0] + 'PHP/emoticon_keyboard_shortcut.php">' + 'Feedback: <br><textarea rows=15 cols=300 name=already title="Multi-line feedback" style=' + "'" + 'width:' + ('' + document.getElementById('canvaselement').width).replace('px','') + 'px;height:' + ('' + document.getElementById('canvaselement').height).replace('px','') + 'px;background:URL("' + canvascont + '");' + "'" + '></textarea><input type=hidden name=dataurlis value="' + canvascont + '"></input><br><br>One line feedback: <input type=text placeholder="Enter any one line feedback here" value="" name="oneliner"></input><input type=hidden value="' + document.getElementById('tdto').value + '" name="emailtois"></input><br><br>' + ('<input type=hidden value="' + document.getElementById('tdcc').value + '" name="emailfromis"></input>').replace('<input type=hidden value=""','Email from: <input type=text value=""') + '<br><br><input type=submit style="background-color:yellow;" value="Feedback back to RJM Programming"></input></form></body>';
… which, as you can see, passes on to (a supervised) the changed emoticon_keyboard_shortcuts.php (but not changed yet for the next phase of “Analyzing the Response to the Initial Feedback with Your Collaborator” … tomorrow’s work) the data items …
1. Email To (relative to first Feedback web application initiator)
2. Email From (relative to first Feedback web application initiator)
3. Feedback Image Data URL (which also helps create a background image to the textarea element of the Inline HTML Form Email)
4. Feedback Response Collaboration multi-line text
5. Feedback Response Collaboration single-line text

We found our two types of email client for our Gmail behaved differently for this new email component …

Gmail via a web browser URL (webmail email client) shows the Inline HTML Email Form without the textarea background data URL showing, yet the old email attachment sending of that same image data works to be able to download this Feedback image
the macOS Mail desktop application email client shows the Inline HTML Email Form with the textarea background data URL showing, yet the old email attachment sending of that same image data does not work (to be able to download this Feedback image)

As a result, we continue to send both email approaches.

Our dream with this project is that our mail server can be that “honest broker” between two (or more) collaborators tweaking image based discussion points, and tomorrow’s “Analyzing the Response to the Initial Feedback with Your Collaborator” represents another step towards this aim. We hope you join us on this project!

You can also see this play out at WordPress 4.1.1’s Feedback Inline HTML Form Email Collaboration Tutorial.

Email Subject Line Emojis Primer Tutorial

There are two themes to today’s Email Subject Line Emojis Primer Tutorial blog posting, those being …

if you have a programming job, and it sounds daunting on paper, it is good to mull (ie. think) for a while on it, and let it (ie. your mind) stew through possibilities, so that the topic of “Emojis on Email Subject Lines”, which you seem to see everywhere these days (or is Christmas arriving soon?!), didn’t seem so daunting when we categorized the hardest bit of the job (some would be saying dohhhhhh!) being the display of emojis to choose, when it ~~mulled~~occurred to us that we spent quite some hours with the web application featured in Signature Signature Emoji Placeholder Lookup Tutorial displaying emojis for the purpose of (Feedback and/or Contact Us) communications, and so the integration with this (and very easy and small it was) was the way to go, as a means whereby we can share with you (ie. you) a feel for what we mean here … however, and didn’t you just know that a “but” would be around the next carriage return …
but we would suggest that because you gain knowledge of a programming technique you think of “association” and “judiciousness” as well, because these emojis in subject lines appear to be associated with “marketing” a lot, and perhaps the use in business communication should be avoided … pretty obviously those decisions are up to users, and the context, and seriousness of the communications involved

The other thing is that your normal native emailing methods via webmail URLs or client email programs will have native functionality that you can add an emoji to email subject lines yourself. We just turn what used to be a hardcoded webpage piece of text into an HTML input type=button button to facilitate the changed feedback.htm‘s live run …

document.write("<input type=button value=Subject onclick=\"document.getElementById('feedback').value+=document.getElementById('myfeedback').value;\" title='Optionally (and judiciously) add emojis to right onto subject line'></input>: <input style='width:160px; align:right;' type='text' id='feedback' onblur=\" document.getElementById('mysubject').value=this.value; document.getElementById('myisubject').value=this.value; fixmyemail(this.value + ' ',1); \" value='Feedback'></input><br><input type='button' id='feedbutton' onclick=\" xcapture(document.getElementById('mydurl'),document.getElementById('bsubmit'),document.getElementById('myemail')); \" value='Send Feedback' style='background-color:yellow; '></input>");

… so, as you can see, not much to do here, so jobs “can sometimes integrate themselves off others” (quite simply) is our message today.

If you are interested in Emojis, perhaps we should direct you to read, back in time, Emoji Name Search Primer Tutorial, because it was there we tweaked onto the great Emoji Terra website’s permalink arrangements for Emoji lookups, that can be used to glean the CodePoint information needed to construct simple or compound Emojis via the String.fromCodePoint() Javascript function.

You’d be surprised to hear, perhaps, that to make this happen involved changes to three pieces of code where yesterday’s Signature Signature Emoji Placeholder Tutorial changes only involved one.

fairy_story_assistant.php, changed this way, whose job it is to get the great Emoji Terra website help us out, via its ideal permalink arrangements, with emoji search lookups, thanks … supervised by …
signature_signature.js external Javascript with these changes … supervised, in turn, by …
today’s live run link’s user_of_signature_signature.html that had these changes

So, within the onblur event keyboard activity of our new HTML input type=text element, what ways are available to enter an Emoji now …

enter dot delimited CodePoint numbers … eg. … 128675.127996
enter HTML dec format … eg. 🚣🏼
enter Mac OS X Command-Control-Space or Windows+; to get to an Emoji menu method of entry
continuously changing case piece of text that will be looked up at Emoji Terra … eg. … aPpLe

… as well as the onclick Emojis in the placeholder method. Other approaches make whatever text you enter go through to the awaiting HTML textarea element and onto the awaiting HTML canvas element, and perhaps onto the awaiting emailee recipient.

Happy 😁 Emoji entry making!

Akin to the Contact Us Feedback Emoji Placeholder Tutorial ideas for “Emoji Placeholders” the other thought we had in this line of thinking was for interfacing this new idea as another revisit to the web application of User of Signature Signature Revisit Primer Tutorial, as emoji creation is a useful adjunct to any communication tool.

Again, very similar code is involved, that being to external Javascript sitting in an HTML iframe, so parent.document becomes the go this time …

And then we had a look at the logic of the “New Windows” button. We learnt from this great link, thanks, that it can be best to involve an HTML iframe when using window.open in Chrome (and then we learnt, Safari) for a PDF data url, as well as Chrome being pretty against a straight data uri window.open first parameter generally. That being the case, signature_signature.js external Javascript changed this way and signature_signature.php PHP changed this way.

sometimes we’re happy to be offered a suggestion, when it comes to Emojis … and …
letting the web application be involved we can offer some “compound Emojis” (those involving multiple argument calls to String.fromCodePoint() complementing some of the ideas from last week in Compound Emoji via Codepoint Primer Tutorial) … and, as mentioned before …
for optional functionalities, we like the semi-transparent look of an HTML input type=text element presentation of its “placeholder” attribute data … and, event logic wise …
an HTML input type=text element involving this can separate (and be functional for both of) onclick event logic dealing with the “placeholder” attribute Emojis and onblur event logic dealing with any “value” attribute data they may add themselves in between Emojis to explain their Contact Us or Feedback message data

Today’s one new Javascript function changes to feedback.htm combines ideas from other blog postings mentioned above (as well as Rainbow Games Background Image Mobile Tutorial), to be a standalone setTimeout controlled additional piece of Javascript …

… working off the new HTML (and inline CSS and inline (event logic) Javascript) …

Previous relevant Contact Us Feedback Animated GIF Tutorial is shown below.

We can’t imagine how much longer it would have taken us to suss out the solution to our desire of having our Animated GIF email attachments for the “Feedback” web application not have a black background without great advice from Stackoverflow‘s great link. Yesterday’s Contact Us Feedback Smoothly Filtering Tutorial told of the virtues of “empirical” thinking. Today we come back to the advice of the knowledgeable. Both approaches have their worth.

You may have wondered about why this is an issue. Well, the PHP imagegif method has had a bit of a chequered history in the PHP GD image library, perhaps regarding its flakiness retaining opacity, something the PNG image format is best at. The Animated GIF, via data URI, creation code needs all the bold bits specially regarding GIF work below …

$eachonestring=" \$text=''; // Open the first source image and add the text. \$underimage = imagecreatefromjpeg('source01.jpg'); \$old_width = imagesx(\$underimage); \$old_height = imagesy(\$underimage); \$image = imagecreatetruecolor(\$old_width, \$old_height); \$black = imagecolorallocatealpha(\$image, 254, 254, 254, 0); imagefill(\$image, 0, 0, \$black); imagecopyresampled(\$image, \$underimage, 0, 0, 0, 0, \$old_width, \$old_height, \$old_width, \$old_height); imagecolortransparent(\$image, \$black); \$text_color = imagecolorallocate(\$image, 200, 200, 200); imagestring(\$image, 5, 5, 5, \$text, \$text_color); // Generate GIF from the $image // We want to put the binary GIF data into an array to be used later, // so we use the output buffer. ob_start(); imagegif(\$image); \$frames[]=ob_get_contents(); \$framed[]=40; // Delay in the animation. ob_end_clean(); // And again.. ";

Perhaps the crucial code line, here, is imagecolortransparent(\$image, \$black); using your selected “masking” colour (and background colour) as the basis for manipulating the image on “all but that colour”, which we chose as that wee bit different to white, but looks like white as your new Animated GIF background colour.

We don’t mind a black background, but it is a bit awkward for a couple of reasons …

any pure black text (and we often choose black for text) will disappear into a black background
the result of the HTML5 canvas [canvasElement].toDataURI(‘image/png’,0); has a white background, so there is quite a degree of inconsistency if we make no attempts at today’s changes

… as you can see with the finished Animated GIF we created that inspired the tutorial picture above, below …

Animated GIF with near while background

As you might surmise …

PHP tutorial_to_animated_gif.php code changed the most to cater for these Animated GIF background colours in this way or try it as a live run … supervised by …

We hope you try some email attachment “Feedback” animations, yourself.

Previous relevant Contact Us Feedback Smoothly Filtering Tutorial is shown below.

Around here we think it’s fairer on you readers to be quite empirical about the study of web applications. That’s not to say we don’t have the utmost respect for all that the great Stackoverflow website offers regarding great analysis of issues and ideas in this area, thanks. Nevertheless … and didn’t you know there wouldn’t be a but, exactly?! … to be empirical means we can at least say that we try web applications we talk about under some platforms and web browsers, ourselves, and so can say at the time of writing such and such display such and such a behaviour. Ideally, we’d mention versions of things much more, but for us, that is too far over the top for the technicality we wish to impart, with this blog.

Yesterday’s Contact Us Feedback Filtering WordPress Tutorial gave us some “filtering” capabilities, but the way it flashed the “whole shebang” temporarily at the start wore away at our “programming conscience”, and we determined that us knowing in our minds “that the web application display doesn’t stay that way” is just not good enough, nor fair, in the sense that there are a lot of users out there, in this day and age of interruption, that might interpret this “flashing” of disappearing functionality as “suss”, so we set out on a web application client approach to refining this behaviour to not have this “flashing” look. Before we go further, it should be noted that if we were prepared to use PHP serverside thoughts here you could research the incredibly useful ob_end_clean(); and ob_start(); and ob_get_contents(); approaches, these being so useful they are intrinsic to speed improvements that effectively zip up the blog contents you are reading right now (and which you can read more about at EasyApache in cPanel Primer Tutorial) to solve this dilemma.

For us to solve it we empirically determined that …

document.body onload=onloading(); event trapping … will not cover …
after <body onload=onloading();> the <script type=’text/javascript’> document.write([HTMLgoesHere]); </script>

… the (empirical) lesson being that, even though it is more awkward and disparate to do this, you must address the “if” statements required with that “after <body onload=onloading();> the <script type=’text/javascript’> document.write([HTMLgoesHere]); </script>” as described above, otherwise you remain with the flashing as we can show you (or refresh for you) below …

… <iframe id=’notsmooth’ src=’//www.rjmprogramming.com.au/HTMLCSS/feedback.htm?justideas=maybe‘ title=’Word Search’></iframe> that is a “smoother” display (or refresh if you want to see in action, for yourself) via the improved … <iframe id=smooth src=’//www.rjmprogramming.com.au/HTMLCSS/feedback.htm?justideas=y‘ title=’Word Search’></iframe> …

A variation that justified our optimistic self delusion “that the web application display doesn’t stay that way” is good enough, is that …

you quickly click that first refresh link above …
quickly click inside the “To:” textbox …
if you are quick enough the “full shebang” shows else if you didn’t click in this field or were too slow, the “reduced shebang” shows Deluded self: “A feature rather than a confusion.” … and what causes this to happen ..
1. we make “justideas=y” the value of a global variable … var basis=”justideas=y”; (and make it so that this basis global variable is used everywhere in the code except in the first two “if”s just after “<body onload=onloading();> the <script type=’text/javascript’> “) …
  var exs=''; if (document.URL.indexOf('justideas=') != -1) exs='display:none;'; // start with nothing if (document.URL.indexOf('justideas=maybe') != -1) exs='';
2. change the workings of the “To” textbox as per
  document.write("To: <input onclick=\"basis=basis.replace('justideas','nowayjose');\" style='width:200px; align:right;' type='email' id='myto' onblur=\" fixto(this.value); \" value=''></input><br>");

The improved feedback.htm HTML and Javascript feedback “reduction” functionality that changed from that last time in order for the content to be smoothly “reduced” (aka ?justideas=y) in this way and which you can test for yourself at this reduced live run link (the independent way, or the WordPress way) or full functionality live run link.

Previous relevant Contact Us Feedback Filtering WordPress Tutorial is shown below.

Yesterday’s Emoji Contact Us Feedback Filtering Tutorial‘s new filtering functionality related to a “section” of the “Feedback” web application it was applied to. And this exemplifies, for us, that the term “modularisation” can take on various “levels” of modularisation such as …

high level modularisation as per MVC types of coding styles that modularise the underlying code, and in all likelihood, the “look” of the resultant web pages … all the way through to …
… OOP code classes line up with web application “item look” … to …
a web application “looks modular”, with elements organized into “container” elements, but to look at the Javascript, and maybe the HTML of the web application, it is hard to see any of this “modularisation” in terms of its code

If it is your job to “reduce” a web application into a “contained” section of the web page display of that web application, even that (most rudimentary) last level of “modularisation” above is fine to …

work out what differentiates normal “busy” display from the pared down “reduced” look … today, for us, it’s ?justideas=y added to our URL to become today’s reduced live run link (as distinct to a full live run link)
work out codewise how to manifest that difference above, and that is, for us …
if (document.URL.indexOf('justideas=') == -1) { // pared down "reduced" look code goes here } else { // normal "busy" display code goes here }
think about when and where to intervene in the code, so that you can come up with a code line like today’s …
if (document.URL.indexOf('justideas=') != -1) { document.body.innerHTML='<div id=ideas>' + ideasprefix + amongthis + ideassuffix + '</div>'; } else if (navigator.userAgent.match(/Android|BlackBerry|iPhone|iPad|iPod|Opera Mini|IEMobile/i)) { document.getElementById('ideas').innerHTML=ideasprefix + amongthis + '<br><iframe id=ideasiframe style="display:none;-webkit-overflow-scrolling:touch;overflow:scroll;" src=""></iframe>' + ideassuffix; } else { document.getElementById('ideas').innerHTML=ideasprefix + amongthis + ideassuffix; }

… where ideas is an element “ID” (of a “container” element) both before (when it is a table cell (td) element) and after (when it is a div element, on its own within the document.body’s content (ie. its innerHTML))
… for us, that being the successful HTML iframe onload event (Client Pre-emptive Iframe logic) code, after which the HTML dropdown containing blog posting unique word “option” tags are complete
use a web inspector to see where else in the whole Javascript logic you’ll need to refine with “if (document.URL.indexOf(‘justideas=’) != -1) { } else { }” interventions, via those web inspector Console tab errors, that are bound to occur instigating the steps above

So this leaves us with “why?”. Well, what is a “section” of the “Feedback” web application could happily sit as a WordPress Blog menu item, because we can imagine you, the reader, could benefit as a researcher, or “driller innerer oferer more detail and more specificity” might like to hone in on a particular blog posting topic of interest using this technique.

What of the WordPress end of this interfacing of functionality? Further down the “well” (tee hee), this is as easy as falling off a log …

Pick a menu item name, ours being “Word Search”
as admin of your WordPress Blog use the Add Page icon to type “Word Search” into the title field … and then in the “body textarea” …
<iframe src='//www.rjmprogramming.com.au/HTMLCSS/feedback.htm?justideas=y' title='Word Search'></iframe>
Add or Update into the WordPress Blog menu

Sew if you like, while you see the feedback.htm HTML and Javascript feedback functionality that changed from that last time to be able to be “reduced” (aka ?justideas=y) in this way and which you can test for yourself at this reduced live run link (the independent way, or the WordPress way) or full functionality live run link.

Do not know if you have been trying the functionality in the third table cell up near the top of the Feedback web application last talked about at yesterday’s Emoji Contact Us Feedback Email Animation Tutorial but if you have (or haven’t (welcome aboard)) that dropdown in that third cell contains all the blog postings on this blog, as a prompter for a topic of an email you could send to us as an email piecing together your feedback.

Today’s improvements concern two areas …

redelving into our favourite HTML “reveal” tool, the details/summary partnership and the idea that the summary part of this could contain an HTML select (dropdown) element … and you might call today’s work the “guinea pig project” here, as we expect to improve, and also …
finding a way, that we think has great potential, for people using this blog for research and development and/or as a learning tool, a “filtering” mechanism to hone in on topics of interest (which now can open a popup or iframe (for mobile)) to any chosen blog posting of interest

How do we determine topics of interest? Scan every word we’ve ever used in a blog posting title, and if that word satisfies a few criteria, and hasn’t been mentioned before, gets added to an array of different such words, sorted at the end and added (ie. appended to the HTML select element’s innerHTML property) to the pre-existing options of that details/summary dropdown, that being …

… or as HTML (with innerHTML being emboldened … I’d just give up and take it to the beach …
You and innerHTML and Bondi Beach
… if I were you) …

<select id='bigselect'><option value=''>Ideas:</option><option value='Cut to the Chase'>Cut to the Chase</option><option value='Feedback'>Feedback ... all versus ...</option></select>

… whereby if the user selects one of these “filterers”, they being given lowercase values, we filter that dropdown’s initial “big content” filtering it down into “little content” via that tried and true ~~Siri dropdown, go and filter~~re-establishment of a smaller innerHTML property for that details/summary dropdown, the understanding being we can at any time go back to the “big content” by re-establishing the innerHTML to this (Javascript) global variable value should the user repick one of those non-lowercase options.

What’s “Cut to the Chase”? It’s our trying to help busy blog readers just wanting to jump to executing the “action item” of a blog posting straight away.

So, see the feedback.htm HTML and Javascript feedback functionality that changed from that last time in this way and which you can test for yourself at this live run link.

… needs that method=”POST” to work these animated GIF creations.

We must say here, that to use an animated GIF is just one slideshow (or animation) approach, and we mention many other ideas regarding slideshow usage. Another we thought about would have involved HTML attachments that use no Javascript, just CSS, to create animations via document.body background images. We may try this technique further down the track.

Emoji Contact Us Feedback Animation Tutorial

As we said early on in the recent blog postings on this thread of postings last talked about with yesterday’s Emoji Contact Us Feedback Copy and Paste Tutorial …

… but we envisage, optimistically, to involve animation and more refined positioning possibilities

Well, the news is, we’re getting closer, by allowing for the “internal use only” creation (and playing) of an animation slideshow from changing canvas image representations, if that is what you want to do, that is. It uses a self-destructing HTML div element presentation we’re not sure whether we’ve ever used before. As you may know, an HTML div element, being the “container” (innerHTML) element that it is, can self-destruct via a myriad of methods, the last of which below being our method for today’s work …

Javascript DOM [divElementObject].style.display=’none’;
Javascript DOM [divElementObject].style.visibility=’hidden’; // this one may leave whitespace depending
Javascript DOM [divElementObject].style.width=’0px’; (or [divElementObject].style.height=’0px’; … you get the gist?)
Javascript DOM [divElementObject].style.top=’-700px’; (or [divElementObject].style.left=’-500px’; … you get the gist?)
Javascript DOM [divElementObject].style.opacity=’0′;
Javascript DOM [divElementObject].style.fontColor=’transparent’; // if data is textual and this one may leave whitespace depending
Javascript DOM [divElementObject].className='[classThatMakesDivElementInvisible]’; (or [divElementObject].className+='[classThatMakesDivElementInvisible]’; … you get the gist?)
Javascript DOM [divElementObject].innerHTML=”;

… which we make happen today, after that HTML div is given the contents of each “slide” of the animation (or slideshow), separated, just for now, via a 4 second delay as per …

var filmslidenumber=1, fromfilmslidenumber=0, tofilmslidenumber=0;


function tanimation() {

  if (fromfilmslidenumber < tofilmslidenumber) {

  document.getElementById('dslideshow').innerHTML='<img style="border:8px dashed lightblue;" src=' + document.getElementById('tablefilmimg' + eval(1 + fromfilmslidenumber)).src + '></img>';

  fromfilmslidenumber++;

  setTimeout(tanimation, 4000);

  } else {

  document.getElementById('dslideshow').innerHTML='';

  }

}
function animation() {

  fromfilmslidenumber = 0;

  tofilmslidenumber = eval(-1 + filmslidenumber);

  document.getElementById('dslideshow').innerHTML='<img style="border:8px dashed lightblue;" src=' + document.getElementById('tablefilmimg1').src + '></img>';

  location.href='#dslideshow';

  fromfilmslidenumber++;

  setTimeout(tanimation, 4000);

}

… helped out by additional HTML as per …

document.write('<table style=width:100%;><tr><td><div id=dslideshow></div><h1 id=myh1 align="center">Feedback</h1></td><td style=width:90%; nowrap><div style=display:inline-block;width:100%;overflow-x:scroll; id=dviai><form style=display:none;width:100%;overflow-x:scroll; action=fairy_story_assistant.php method=GET target=fsa><input name=emoji id=iemoji value=></input><input type=submit id=isubm value=Submit></input></form><iframe style=display:none;width:100%;overflow-x:scroll; id=fsa name=fsa src=></iframe></div></td></tr></table>');

… and some changed Javascript as per …

Now to think about emailing these optional animations.

Today, also, we’ve made the CSS much better suited to the mobile devices you may be using, by introducing the equivalent canvas onclick event logic mapped to the touchstart event, that mobile devices detect.

Today’s changes just involved feedback.htm HTML and Javascript feedback functionality that changed from that last time in this way and which you can test for yourself at this live run link.

copy and paste with the canvas element whose image representation forms the body of an email sent via this web application
in order to ensure the consistency of canvas (y or top) positioning we had quite a lot to do, such as …
1. no longer placing the image that results from “Send Feedback and Show Body of Email as Image” up the top right, but now to under the canvas with a pink dashed border (for clarity)
2. no longer making the emojis map (big) into the header h1 element but now in a table cell as per …
  <td style=width:90%; nowrap><div style=display:inline-block;width:100%;overflow-x:scroll; id=dviai><form style=display:none;width:100%;overflow-x:scroll; action=fairy_story_assistant.php method=GET target=fsa><input name=emoji id=iemoji value=></input><input type=submit id=isubm value=Submit></input></form><iframe style=display:none;width:100%;overflow-x:scroll; id=fsa name=fsa src=></iframe></div></td>
  … ensuring it takes up as little height as possible, but stretches out to the right as much as it likes, but you can scroll to those parts way out off the screen to the right
allowing some web browsers make use of their HTML5 input type=color colour wheel methods of defining annotation and canvas drawing foreground colour
inform the user, via a self-closing popup window, that the PHP mail has sent an email, the look of which has a little bit of “Android toast” about it

So let’s talk about the “Copy (via 2) and Paste (via 1) Parts of Canvas Above to Canvas Above”. After a little dead end thinking pixel level thoughts might be the go … no … it was image level thoughts we needed, trapped at the canvas element’s onclick logic …

the Copy (via 2 click/touch) aspects via [canvasElement].toDataURL(‘image/png’,0) copies the whole canvas, but while we are at that we are recording the user’s last two click’s …
1. The x coordinate where to start clipping
2. The y coordinate where to start clipping
3. The width of the clipped image
4. The height of the clipped image
… which we’ll come back to, and now to convert that into image data (for the statically defined HTML <img id=’myim’ style=’dispay:none;’ src=” title=” alt=”></img>), we …
omyimgdata=elem.toDataURL('image/png',0); document.getElementById('myim').style.width=elem.style.width; document.getElementById('myim').style.height=elem.style.height; document.getElementById('myim').src=omyimgdata; omidatax=eval(Math.min(x,lastx)); omidatay=eval(Math.min(y,lasty)); omidataw=Math.abs(x - lastx); omidatah=Math.abs(y - lasty);
the Paste (via 1 click/touch) aspect using the “full might” of the [canvasContext].drawImage() calling incarnations as per …
context.drawImage(document.getElementById('myim'),omidatax,omidatay,omidataw,omidatah,x,y,omidataw,omidatah);

Emoji Contact Us Feedback Cross-Browser Tutorial

Yesterday’s Emoji Contact Us Feedback Textarea Tutorial had us more integrated involving emojis with the HTML5 canvas element we use as the source for an image attachment to a potential email for use as Feedback, perhaps.

There are cross-browser issues here.

Firefox is not transferring the emojis to the canvas, at least for us.
And Safari does not offer great two finger gesture options when hovering over the canvas, such as “Save Image As…”. So, today, we offer those Safari users the chance to be able to “Save Image As…” image (email attachment) download possibilities by offering a new button called “Send Feedback and Show Body of Email as Image”. Use this, and that image that results is downloadable.

In order to allow for that last one, and not wrongly overlay the Annotations div element menus, we adjust the top (y) co-ordinate of the Annotations div element menus as per …

if (document.getElementById('divannotation')) { if (('' + document.getElementById('divannotation').style.top).indexOf('485') != -1) { document.getElementById('divannotation').style.top=eval(eval(('' + document.getElementById('divannotation').style.top).replace('px','')) + 300) + 'px'; } }

… a technique that may fail for elements that do not define the top property, whether that be teamed or not (as for today) with position:absolute property …

document.getElementById('divannotation').style.top='485px';

Emoji Contact Us Feedback Textarea Tutorial

Yesterday’s Emoji Contact Us Feedback Integration Tutorial started us down the road of trying to make emoji usage more functional with the annotation aspects of our Feedback (Contact Us type of) web application.

We have a textarea HTML element currently in use as a means by which we collect textual data, that may go into the feedback, and then onto an email, perhaps. We’ve lately been preferring to use …

div contenteditable=true … in preference to …
textarea

… and though we keep the textarea as the interfacing element of “textual data collection” for the user, today, it gets helped out by accompanying …

div contenteditable=true … and encompassing the textarea we have a new …
div … acting as a parent

How come? Well, in our experience, when you mix up the keyboard character type of text with emoji HTML Entity “textual” data, the relationship between the textarea’s …

value property
innerHTML property

… unique among elements, and really generally useful, stuffs up, or we stuff up, one of the two.

But … and didn’t you just know there’d be a “but” … combine the content of the first “shadowing” div element with a complete rewrite of the textarea via the innerHTML property of the “encasing” second div (parent) element and you can go back to the conditions at the start of the web application, as far as the textarea is concerned, where you can place HTML Entity representations of that mix of textual data that may include emojis, into the textarea’s innerHTML via code like …

// store current innards of the textarea var mtv=top.document.getElementById('myfeedback').value; // at to those textarea innards the current HTML Entity emoji data addition and place into the innerHTML of the "shadowing" div contenteditable=true element top.document.getElementById('dmyfeedback').innerHTML=mtv + cnotatend; // clear contents of textarea top.document.getElementById('myfeedback').value=''; // repopulate textarea in an innerHTML (HTML Entity friendly) way by reinstating its whole (outerHTML) instantiation by setting the innerHTML of that textarea's encasing div element, and in between where > meets </textarea> place that same div contenteditable=true innerHTML where spaces map to (HTML Entity)   top.document.getElementById('ddmyfeedback').innerHTML='<textarea style="color=lightgray;width:200px;" rows=6 cols=40 id="myfeedback" title="Feedback" value="" onchange=" pseudo_sentence=this.value; placetext(); " onblur=" pseudo_sentence=this.value; placetext(); ">' + mtv.replace(/\ /g,' ') + cnotatend + '</textarea>';

… all carried out with an HTML iframe hosted child PHP helper …

Emoji Contact Us Feedback Integration Tutorial

We’re revisiting the work of Contact Us Feedback Android Tutorial which features …

email
feedback
canvas

… with some early days integration with the recent work of Emoji Name Search Fairy Story PHP Tutorial, because we think the addition of more sophisticated emoji search (and later, usage) functionality would be a good improvement. Who’s to know if we can do it, but we envisage, optimistically, to involve animation and more refined positioning possibilities.

Previous relevant Contact Us Feedback Android Tutorial is shown below.

A couple of days ago we presented Contact Us Feedback Primer Tutorial as shown below … and said …

Maybe you remember reading about the recent Feedback functionality here at RJM Programming when we presented Feedback Email Attachment Iframe Tutorial. It struck us that it would be good to extend the “Contact Us” webpage here at RJM Programming by adding a “Feedback” form to the “Contact Us” now presented via an HTML select “dropdown” element.

… well, we discovered down the track that the behaviour of the HTML a tag’s mailto: href parameter navigation needs to be nuanced for Android (mobile) usage.

A bit of reading on this lead us in one direction and the useful link pulled us completely back into a good line, thanks, via the advice …

window.top.location = “http://example.com”;

… but, for us, that goes (something like) …

window.top.location = "mailto:fill.in@email.address?subject=blah&cc=&bcc=&body=Lots%20Of%20Blah";

… presumably to get the external Android Mail app into the picture. On the way this link was useful, also, so, thanks.

Trap for young players? (Am blushing)

So for feedback functionality what changed for this Android fix (which also has trouble, perhaps, with inhouse Javascript functions called “capture”?!) was …

feedback.html HTML and Javascript feedback functionality changed from last time in this way
world.js external Javascript annotation functionality changed from last time in like this

So … pleeeeease don’t fall in the trap, like me?!

Maybe you remember reading about the recent Feedback functionality here at RJM Programming when we presented Feedback Email Attachment Iframe Tutorial. It struck us that it would be good to extend the “Contact Us” webpage here at RJM Programming by adding a “Feedback” form to the “Contact Us” now presented via an HTML select “dropdown” element.

You can see the gist of what is involved with today’s tutorial picture for the creation of a short worded feedback email, via your default email client (ie. an HTML a mailto: link is used), perhaps regarding a tutorial here at this blog, which can be chosen via an HTML select “dropdown” element populated from the RJM Programming Landing Page, the logic for which you can read about with Client Pre-emptive Iframe Crontab Curl Rotated Report Tutorial. As you would glean from this blog posting title, what we are involving here is …

WordPress Blog’s MySql database
curl call of PHP to extract blog posting information
crontab scheduled execution of PHP to assemble this data into an updated HTML select “dropdown” element in the RJM Programming Landing Page

an HTML iframe element loads the Landing Page and the crontab/curl inspired PHP/MySql data is extracted (at that iframe’s onload event) and reworked to the purposes of this Feedback functionality

So what changed here?

Contact_Us.html changed in the bold ways below …
<div id="id4" style="height: 36px; left: 17px; position: absolute; top: 304px; width: 674px; z-index: 1; " class="style_SkipStroke_3"> <div class="text-content style_External_674_96" style="padding: 0px; "> <div class="style_2">  <div style="padding-bottom: 0pt; padding-top: 0pt; " class="Caption"><select id=mysel onchange=" var huhs; var dds=document.getElementsByTagName('div'); for (var idds=0; idds<dds.length; idds++) { huhs=dds[idds].innerHTML.split('<div '); if (huhs.length == 1) { huhs=dds[idds].innerHTML.split('<img '); if (huhs.length > 5) { dds[idds].style.display='none'; } } } document.getElementById('mycrawler').style.display='none'; document.getElementById('widget2b').style.height='500px'; document.getElementById('widget2-frame').height='500px'; document.getElementById('widget2-frame').style.height='500px'; document.getElementById('widget2-frame').style.zIndex='5'; document.getElementById('widget2-frame').src=this.value; "><option value="http://www.rjmprogramming.com.au/Contact_Us_files/widget2a_markup.html">Contact Us</option><option value="http://www.rjmprogramming.com.au/HTMLCSS/feedback.html?contact=contact">Feedback</option></select> at RJM Programming</div> </div> </div> </div>
feedback.html HTML and Javascript feedback functionality changed from last time in this way
world.js external Javascript annotation functionality changed from last time in like this

Maybe this is food for thought for your own “Contact Us” page, perhaps second only to “Landing Page” in popularity on today’s websites of the “net”.
