Map Chart Geo Chart Post Tutorial

Further to yesterday’s Geo Chart Resizable Text Overlay Tutorial another integration aspect uncovered using …

… for the “T” (for TimeZone) inhouse menu option, where the amount of data precluded the use of $_GET[] ( ie. ? and & ) arguments, with regard to URL length restrictions, we found, trying out Russia’s TimeZone places, in getting from the Map Chart through to the Geo Chart above, there were issues. And today, we track down those issues in amongst the codelines of our Javascript toolong function checking for this issue …

… as another “phase 1” item in our latest project aims, as per …

  1. Help itself … map.php … phase 1
  2. Redirect to Image Chart Map Chart … map.php and/or geo_chart.php … just after first prompt … phase 2
  3. Caller form method=POST map.php action interventions at onsubmit event … non map.php … phase 3
  4. Transfer the onclick prompt window functionality over to geo_chart.php … phase 4

Also changed, we do more automations of the clicking of the Map Chart’s “Geo” link (to the Geo Chart) …

Geo Chart Resizable Text Overlay Tutorial

There is little doubt that when you spend a concentrated block of time interfacing among software parts (or modules) playing their “bit parts” in an overall solution to 42 an aim, you learn about the strengths and weaknesses of these components to the solution. Aim?! Yes, remember Google Chart Image Chart Map Chart Plotting Tutorial …

  1. Help itself … map.php … phase 1
  2. Redirect to Image Chart Map Chart … map.php and/or geo_chart.php … just after first prompt … phase 2
  3. Caller form method=POST map.php action interventions at onsubmit event … non map.php … phase 3
  4. Transfer the onclick prompt window functionality over to geo_chart.php … phase 4

… being our recent aim, and the inspiration for the Region Picker of yesterday’s Region Picker Sticky Scrolling Tutorial, which became both …

  • a component part of the project above … as well as …
  • a standalone component

… the reason recently that the component part role above has not been centre stage being that its interfacing to the Geo Chart was successfully seamless, hence we can concentrate on how it performs in its standalone form knowing that improvements will flow through to our “large picture” project above.

But the Region Picker showed us with its calling of the Geo Chart that that Geo Chart component could improve with two nuances …

  • be able to rescale the Geo Chart proportionally via its width and height arguments …

Also back at the Region Picker there was an annoyance where if you clicked on a right hand cell link for an inhouse geographicals menu to appear, but hovered over another link getting away, that resultant Javascript prompt window could be tainted by the last hovered over link’s data. Well, with some setTimeout scenarios we hope for a better user experience with …


var noslpt=false, gcis='', gwhat='';

function yesslpt() {
noslpt=false;

lastcode=cis.trim();
if (('' + cis + ' ').substring(2).substring(0,1) == '-') {
lastcountrycode=cis.substring(0,2).toUpperCase();
} else if (eval('' + cis.length) == 2) {
lastcountrycode=cis.toUpperCase();
}
if (what.indexOf(' (') != -1 && what.replace(/\ /g,'').indexOf('()') == -1) {

With our current Region Picker web application of recent blog postings, like yesterday’s Region Picker Geographicals Tutorial, you may have noticed …

  • quite a bit of CSS position: fixed; positioning … fairly easily understood as an element occupying screen space where its left and top (in our case) properties are set … but in order to improve scrolling in the right hand table cell area (where, if filled with country Slovenia’s region list, as one example of many, it would overflow down below the webpage and these elements would not be able to be scrolled to) we resorted to …
  • CSS position: sticky; positioning … for one of the first times we can remember, the “heads up” to try it coming from this excellent link, thanks, and an explanation of “sticky” from W3schools, thanks, feels required here …

    An element with position: sticky; is positioned based on the user’s scroll position.

    A sticky element toggles between relative and fixed, depending on the scroll position. It is positioned relative until a given offset position is met in the viewport – then it “sticks” in place (like position:fixed).

    Note: Internet Explorer, Edge 15 and earlier versions do not support sticky positioning. Safari requires a -webkit- prefix (see example below). You must also specify at least one of top, right, bottom or left for sticky positioning to work.

    … as we just can’t explain it well enough ourselves, but know in our heart of hearts, that an arrangement living between relative and fixed as far as that CSS position property goes, is a thing we are constantly reaching for (but please don’t think this means it will work for you everywhere … it depends)

The other part of the webpage we couldn’t scroll to was the mid-webpage select (ie. dropdown) element when populated by the regions of a country like Slovenia. We took the advice of this other excellent link, thanks, where it offers an example piece of CSS …

.fixed-content {
position: fixed;
top: 0;
bottom:0;

width: 100vw; /* viewport width */
height: 100vh; /* viewport height */
overflow-y: scroll;
overflow-x: hidden;
}

… the modelling of which, for us (where Javascript variable sp1 points at our hosting element) …


sp1.style.position='fixed';
sp1.style.left='' + eval(40 + eval('' + document.getElementsByTagName('span')[0].getBoundingClientRect().right)) + 'px'; // myr.left
sp1.style.top='10px'; // myr.top
sp1.style.border='5px dotted yellow';

sp1.style.width='160px';
sp1.style.height='80%';
sp1.style.bottom='0px';
//sp1.style.minHeight='100%';
sp1.style.overflowY='scroll';
sp1.style.overflowX='hidden';

… paid dividends. Thanks everybody!

  • geographicals … as possible … as a “marker” representative position

… because, as possible, this opens up possibilities for our inhouse Javascript prompt window menus, where we add options for …

  • Airports
  • Sun Angle
  • Moon Angle
  • Coriolis Effect
  • Google Earth
  • Geo Chart

Region Picker Keyboard Tutorial

The menus we’ve been seeing in our latest Region Picker web application blog posting thread, like for yesterday’s Region Picker Post Tutorial, ask for a one letter answer. As such, that can mean “hotkey” non-mobile logic can be the go. And so, in a similar way to how it tweaked with us “to think keyboard” with our SOS Game presented in the recent SOS Game Keyboard Tutorial, we realized a good initiative with our Region Picker web application, to save ourselves from the need for Javascript prompt windows, perhaps, in a non-mobile environment, we could code for a document.body …


<body onload="onl();" title="Regions of Each Country on Earth" ondblclick="tryit();" onkeydown="return okd(event);">

… coding for the keyboard “onkeydown” event with some new Javascript logic …

charx=charx;

menuize('T');
} else if (('' + e.keyCode) == '71') { // Google
menuize('G');
}
return true;
}

function menuize(rans) {
var rdescis=lastplace;
if ((rans + ' ').toUpperCase().substring(0,1) == 'W') {
if (rdescis == '') {
window.open('//wikipedia.org','_blank','top=180,left=400,width=600,height=600');
} else {
window.open('//wikipedia.org/wiki/' + encodeURIComponent(rdescis.replace(/\ \(/g,', ').replace(/\)$/g,'')).replace(/\%20/g,'_'),'_blank','top=' + ys + ',left=' + xs + ',width=600,height=' + Math.max(100,eval(-100 + screenheight - ys)));

… represents, to us, a layer of functionality on top of any existing functionality, helping the user experienece for non-mobile platform users.

And that third parameter of window.open popup window (and iframe method=POST scenarios) gets a makeover to position popups more in keeping with where the user has been with their mouse movement, for improved context scenarios, and involving new global Javascript variables …

  • xs … screen X …
  • ys … screen Y … we detect and follow (back at any caller), both at the called and caller, in the image_chart.php helper Javascript code …

Region Picker Post Tutorial

Yesterday’s Region Picker Hover Tutorial‘s navigations worked off (what we like to call) a GET argument methodology regarding URLs (involving ? and & controlled arguments on the address bar URL) it calls on Image Chart data creators. But even with the ISO-3166 codes (effectively nicknames) used, some countries have lots of regional codes associated with them, and the GET limitations to URL length (for our website less than 1000) means we have to open the door to other approaches for these long URL calls.

Luckily what we are calling is PHP and it can accept POST arguments (ie. $_POST[] array members as distinct from $_GET[] “?” and “&” GET argument members).

Here’s what the scenario looks like for Romania before our fix today …

… and below, the improved scenario after …

To make this happen, we funnel the relevant window.open call through our inhouse “wrapper” Javascript function …

<?php echo ”

function windowopen(a1, a2, a3) {
if (eval('' + a1.length) > 800 && a1.indexOf('?returnxytoparent=') != -1) {
document.getElementById('callreturnxytoparent').value=decodeURIComponent(a1.split('?returnxytoparent=')[1]);
document.getElementById('postcc').submit();
document.getElementById('fif').style.display='block';
document.getElementById('fif').style.width='470px';
document.getElementById('fif').style.height='800px';
location.href='#prefif';
return null;
}
return window.open(a1, a2, a3);
}

?>

… using an HTML form element …


<form target=fif id=postcc action='//www.rjmprogramming.com.au/PHP/GeoChart/image_chart.php' method=POST style=display:none;>
<input type=hidden name=returnxytoparent id=callreturnxytoparent value=''></input>
<input style=display:none; type=submit id=bfif value=Submit></input>
</form>

… targetting, after a form submit action, a named HTML iframe element …


<iframe name=fif id=fif style=display:none; src='//www.rjmprogramming.com.au/PHP/GeoChart/image_chart.php'></iframe>

… sitting within the table of the webpage, and hashtag navigated to should the need arise in our changed “seventh draft” Region Picker.

Region Picker Hover Tutorial

Region Picker Hover Tutorial

Yesterday’s Region Picker Popup Menu Tutorial introduced, what to us, is …

  • interesting onclick logic associated with the popup window, suiting both mobile and non-mobile platforms … but we can not resist introducing “hover” non-mobile ideas in the category of …
  • interesting onmouseover onmousemove logic … today …

… which, on paper, sounds trivial. But not so, in this scenario. You may recall we started using PHP GD‘s imagecolorat function as a first “port of call” idea with our Clayton’s image map simulation ideas, where this idea may be just okay for discrete onclick scenarios, but not for any non-mobile “hover” scenario. We need another approach. And then it tweaked to us, start (with thisonl document.body onload event logic below) using an HTML canvas element …

<?php echo ”

function thisonl() {
elem = document.getElementById('mycanvas');
context = elem.getContext('2d');
setTimeout(canvasize, 5000);
}

function canvasize() { //(ioel) {
var ioel=document.getElementById('ici');
context.drawImage(document.getElementById('ici'), 0, 0);
document.getElementById('moreturnxytoparent').value=elem.toDataURL('image/jpeg', 0.4);
return true;
}

“; ?>

… to keep up with the clientside (only, now) “hover” solution we’re preferring right now (and maybe even this time tomorrow?!)

And this suits non-mobile users used to seeing useful information as they hover over an element, and in a map element’s case, the equivalent of the “smarts” an image map might offer, except that in today’s case, thanks to colour coding … not an image map in sight!

Yesterday we left off with …

Am sure some of you are onto tomorrow’s plan, given today’s work?! We’ll see what tomorrow brings!

… and we feel we might have “put the mockers” on ourselves, because, as you may have read, Geo Chart Image Chart is due for deprecation soon. In fact, the regime at the moment is fewer and fewer hours up, and we’ll have to turn our attention to alternatives. But what out there can do those regional views where the map effectively hugs the bounds of the data … brilliant, and we think hard to do with your normal Google Charts suite of software? As well as the image element result, even though we need to try out the “ready event” normal Google Charts “print” way to achieve this. So much more useful than involving Javascript. And more fun to work with too, it being a conduit to HTML canvas usage.

Anyway, here we are late in our day with a window of opportunity, and While You See a Chance, Take It we reckon.

And what yesterday’s Region Picker Double Click Tutorial gave us a good framework for is PHP method=GET and PHP method=POST uses of argument returnxytoparent along with our new GD imagecolorat function friend in the changed image_chart.php Google Chart Image Chart Map Chart interfacer …

Region Picker Double Click Tutorial

Region Picker Double Click Tutorial

You might have gleaned from recent blog posts in the thread leading up to yesterday’s Region Picker Hashtag Navigation Tutorial that, regarding web applications/webpages, even though a few years back we’d have been horrified to say it …

  • we like to use the ondblclick event (especially in a multi-purpose button press way) … and in this context …
  • we don’t mind having to use event.stopPropagation() anymore (ie. we used to not get sleep for days worrying about it) (when you want to stop the event bubbling down to a parent element) …
  • we like to use colour coding … and …
  • we don’t mind window.open (with a third argument and so, on non-mobile is a) popup window usage

But that’s just us. We’ll leave it to you to look into all these more, as far as favour, or not, goes with the search engines.

We see the ondblclick event as being in the same line of thinking as the onclick event is (doh!) in the sense that mobile and non-mobile platforms understand it, as distinct from the divide between the touch “gesture” events and the mouse events. And it may be just me, but web browsers seem better with it these days. Maybe just wishful thinking on that last point, for me, though?!

Today, we’ve got another “multipurpose scenario” for an ondblclick event logic coding …


if (sofar != '') {
if (window.self == window.parent && eval('' + screen.width) > 1000) {
document.getElementById('rmore').innerHTML=prebut + '<button id=mychart ondblclick="event.stopPropagation(); dcdomc();" onclick=domc(); style=background-color:' + iccol + ';>Image Chart Map Chart <br><font size=1>(double click uses new window)</font><br> ... showing ...</button><br><br><p id=myp title="' + sofardetail + '">' + sofar.replace(/\|/g, '<br>');
} else {
document.getElementById('subrmore').innerHTML=prebut + '<button id=mychart ondblclick="event.stopPropagation(); dcdomc();" onclick=domc(); style=background-color:' + iccol + ';>Image Chart Map Chart <br><font size=1>(double click uses new window)</font><br> ... showing ...</button><br><br><p id=myp title="' + sofardetail + '">' + sofar.replace(/\|/g, '<br>');
}
}

… calling new …
