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

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;
}

“; ?>

… and follow the excellent advice at this excellent link regarding the use of [canvasElement].getImageData() function to now go …

<?php echo ”

function rgbToHex(r, g, b) { // thanks to https://stackoverflow.com/questions/6735470/get-pixel-color-from-canvas-on-mousemove
if (r > 255 || g > 255 || b > 255)

… 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!

Codewise we needed …

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

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>');

Region Picker Hover Tutorial

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;
}

“; ?>

… and follow the excellent advice at this excellent link regarding the use of [canvasElement].getImageData() function to now go …

<?php echo ”

function rgbToHex(r, g, b) { // thanks to https://stackoverflow.com/questions/6735470/get-pixel-color-from-canvas-on-mousemove
if (r > 255 || g > 255 || b > 255)
throw 'Invalid color component';
return ((r << 16) | (g << 8) | b).toString(16);

… 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!

Codewise we needed …

… to make this happen.

Region Picker Popup Menu Tutorial

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 …

Region Picker Geo Chart Integration Tutorial

We’re tickled pink with our integration of yesterday’s Region Picker Primer Tutorial …

  • Region Picker web application … into …
  • Geo Chart interfacer

… in that we’ve done better than the natural Geo Chart navigation without the Region Picker, which navigates to a new URL slapped onto the same web browser tab. With our integration we have …

  • Geo Chart interfacer parent “base layer” (with as little as one prompt window required) … and if called upon “above this” …
  • Region Picker web application nested in an “overlay iframe” (with large CSS z-index value covering the whole screen) … asks (for as little as) one more verifying prompt window question … and that same tab window content becomes the final …
  • Geo Chart interfacer result web page

And seeing the country regional codes in play, the possibilities mount up here! The user just includes …

&regionpicker

… in a prompt window answer to start using Region Pickers in their user inputs.

Codewise we needed …

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 …

Region Picker Double Click Tutorial

Posted on by
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>');
}
}

SOS Game Cursor Tutorial

SOS Game Cursor Tutorial

In the online woooorrrrllllddd, non-mobile platforms have a whole “hover” woooorrrrllllddd forsaken by the mobile platforms. In that woooorrrrllllddd you can “decorate” or personalize your cursor, that “character” (or perhaps more if you involve SVG+XML protocol cursor customized definitions) which follows your mouse position around the screen.

The event “onmouseover” is called that once on a detection of that hovering concerning an HTML element you are interested in. Event “onmouseover” is not called again until a re-entry happens (and an “onmouseout” event happens as the mouse leaves the environs of your element having previously caused an “onmouseover” event to be called).

If the position remains of interest during that time between an “onmouseover” and an “onmouseout” event be of interest, as it is for us, today, retweaking our recent SOS Game (last talked about with SOS Game Primer Tutorial) functionality, we need to start taking an interest in that element’s “onmousemove” event, called by the system every time the mouse moves within the realms of your HTML element of interest.

Our SOS Game differentiates an “S” user play, from a user “O” play via whether the click (and now hover) positioning is at the top and bottom of the relevant table cell element respectively, decorated by a linear gradient helping background image, with the hovering, as well.

Can the event logic be quick enough? We’ll let you judge for yourself. Probably your impatient players will occasionally fall foul of this hovering advice, but for the main part, we found it helped explain how the game works, having these SVG defined “S” and “O” SVG text cursor customizations happen for our non-mobile SOS Game players out there.

Javascript wise, we fleshed out the (previously not fleshed out) function sback as below, in a way that made it compatible to calls from “onmousemove” events as well as the “onmouseover” events it had already been deployed for …


function sback(e,spo) {
var moxx=0, moyy=0;
var rstis=spo.getBoundingClientRect();
//spo.style.backgroundImage='url("data:image/svg+xml;utf8,<svg xmlns=' + "'" + 'http://www.w3.org/2000/svg' + "'" + ' width=' + "'" + rstis.width + "'" + ' height=' + "'" + rstis.height + "'" + ' viewport=' + "'" + '0 0 100 100' + "'" + '><text y=' + "'" + '0%' + "'" + '>S</text><text y=' + "'" + '50%' + "'" + '>O</text></svg>");';
//spo.style.backgroundRepeat='no-repeat';
//spo.style.backgroundSize='contain';


//elemLeft = spo.offsetLeft;
//elemTop = spo.offsetTop;

e = e || window.event;
e.preventDefault();

if (e.touches) {
if (e.touches[0].pageX) {
moxx = e.touches[0].pageX + document.body.scrollLeft * 0 - elemLeft;
moyy = e.touches[0].pageY + document.body.scrollTop * 0 - elemTop;
} else {
moxx = e.touches[0].clientX + document.body.scrollLeft * 0 - elemLeft;
moyy = e.touches[0].clientY + document.body.scrollTop * 0 - elemTop;
}
//console.log('pos3=' + pos3 + ',pos4=' + pos4);
} else if (e.clientX || e.clientY) {
moxx = e.clientX + document.body.scrollLeft * 0 - elemLeft;
moyy = e.clientY + document.body.scrollTop * 0 - elemTop;
} else {
moxx = e.pageX + document.body.scrollLeft * 0 - elemLeft;
moyy = e.pageY + document.body.scrollTop * 0 - elemTop;
}

if (Math.abs(eval('' + moyy) - eval('' + rstis.top)) <= Math.abs(eval('' + moyy) - eval('' + rstis.bottom))) {
spo.style.cursor='url("data:image/svg+xml;utf8,<svg xmlns=' + "'" + 'http://www.w3.org/2000/svg' + "'" + ' width=' + "'" + rstis.width + "'" + ' height=' + "'" + rstis.height + "'" + ' viewport=' + "'" + '0 0 100 100' + "'" + '><text y=' + "'" + '50%' + "'" + ' stroke=' + "'" + 'gray' + "'" + '>S</text></svg>") 16 0, progress';
} else {
spo.style.cursor='url("data:image/svg+xml;utf8,<svg xmlns=' + "'" + 'http://www.w3.org/2000/svg' + "'" + ' width=' + "'" + rstis.width + "'" + ' height=' + "'" + rstis.height + "'" + ' viewport=' + "'" + '0 0 100 100' + "'" + '><text y=' + "'" + '50%' + "'" + ' stroke=' + "'" + 'gray' + "'" + '>O</text></svg>") 16 0, progress';

Even though it took too long to get to yesterday’s Word Find Game Viewport Tutorial‘s Word Find Game’s level of satisfaction, for us, it was always going to be worth it, because when you overengineer it can mean cloning off that into another useful web application is a “paring down” exercise, more than anything, and this is infinitely easier than “a reinvention of the wheel” scenario, especially where it comes to “cross platform” game usage “user experience” issues.

The fun bit of such an approach, in thinking about what we end up with today is the thought that a …

  • Word Find Game … could be cloned or morphed into a …
  • SOS Game

… we remember from our days at high school, in less than a day. The memory of the SOS Game did not extend to the detail, and so we thank How to Play – SOS for reminders about the status of diagonality, while up versus down and forwards versus backwards concerns were a bit “per se” regarding “SOS”!

It was the confluence of one “onclick” type event to cover, regarding span elements set out in a grid initialized to a non-breaking space ( ie. &nbsp; ) …

  • fill in contents as “S”
  • fill in contents as “O”

… that set us to determining for the span “cell” click, was it positioned …

  • in the top half means “S” … or …
  • in the bottom half means “O”

? This had us converging on changes to the “clicks” mode onclick event Javascript logic …

  • starts looking for Notifications API functionality to keep the players informed about proceedings … and …

… as per Javascript …
