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 …

… 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 …
<?php echo ”
e = e || window.event; e.preventDefault(); if (e.touches) { if (e.touches[0].pageX) { x = e.touches[0].pageX; y = e.touches[0].pageY; xs = pax(e.touches[0].screenX); ys = paa(e.touches[0].screenY); } else { x = e.touches[0].clientX; y = e.touches[0].clientY; xs = pax(e.touches[0].screenX); ys = paa(e.touches[0].screenY); } console.log('pos3=' + pos3 + ',pos4=' + pos4); } else if (e.clientX || e.clientY) { x = e.clientX; y = e.clientY; xs = pax(e.screenX); ys = paa(e.screenY); } else { x = e.pageX; x = e.pageY; xs = pax(e.screenX); ys = paa(e.screenY); }
“; ?>
…
<?php echo ”
function pax(sxis) { if (window.opener) { window.opener.sxiss(sxis); } else if (window.parent) { parent.sxiss(sxis); } return sxis; } function paa(syis) { if (window.opener) { window.opener.syiss(syis); } else if (window.parent) { parent.syiss(syis); } return syis; }
“; ?>
… calling, back at the caller …
function sxiss(invis) { xs=invis; return invis; } function syiss(invis) { ys=invis; return invis; }
… along with a Javascript variable …
screenheight … screen height … used in determining a suitable popup window height …
<?php
$screenheight='0'; if (isset($_GET['screenheight'])) { // passed from overseeing regions_via_countries.html $screenheight=str_replace('+',' ',urldecode($_GET['screenheight'])); } if (isset($_POST['screenheight'])) { // passed from overseeing regions_via_countries.html $screenheight=str_replace('+',' ',urldecode($_POST['screenheight'])); } // // Used later in the PHP writes Javascript ... // echo " var screenheight=('" . $screenheight . "' == '0' ? eval('' + screen.height) : eval('' + '" . $screenheight . "'));
?>

… showing the interplay possible when staying with web application tools within the one domain, using either calling idea of …

popup window via $_GET[] arguments … or …
iframe via $_POST[] arguments

… hosting of our Image Chart helper.

Codewise we needed …

… to make this happen, informing your non-mobile users this is all a possibility, we’re hoping, by displaying …

And in amongst changes today, you’ll see lots of colour related CSS tweaks.

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>

… target_ting, after a form submit action, a name_d 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 ourchanged “seventhdraft” 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) throw 'Invalid color component'; return ((r << 16) | (g << 8) | b).toString(16); } function filloutform(e,isclick) { var p='', hex='', myid=''; e = e || window.event; e.preventDefault(); if (e.touches) { if (e.touches[0].pageX) { x = e.touches[0].pageX; y = e.touches[0].pageY; } else { x = e.touches[0].clientX; y = e.touches[0].clientY; } console.log('pos3=' + pos3 + ',pos4=' + pos4); } else if (e.clientX || e.clientY) { x = e.clientX; y = e.clientY; } else { x = e.pageX; x = e.pageY; } if (eval('' + x) > 2 && eval('' + y) > 2) { document.getElementById('ix').value='' + x; document.getElementById('iy').value='' + y; if (document.getElementById('imode').value == 'click' && isclick != 0) { document.getElementById('imode').value='click'; p = context.getImageData(x, y, 1, 1).data; hex = ('#' + ('000000' + rgbToHex(p[0], p[1], p[2])).slice(-6)).toUpperCase(); document.getElementById('moimode').value='mouseover'; myid=''; if (document.getElementById('myp').innerHTML.indexOf(hex) != -1) { myid=document.getElementById('myp').innerHTML.split(hex)[0].split(' id=\"')[eval(-1 + document.getElementById('myp').innerHTML.split(hex)[0].split(' id=\"').length)].split('\"')[0]; document.getElementById('ici').title=document.getElementById(myid).title; document.getElementById(myid).click(); } else if (document.getElementById('myp').innerHTML.indexOf(hex.toLowerCase()) != -1) { myid=document.getElementById('myp').innerHTML.split(hex.toLowerCase())[0].split(' id=\"')[eval(-1 + document.getElementById('myp').innerHTML.split(hex.toLowerCase())[0].split(' id=\"').length)].split('\"')[0]; //document.title='x=' + x + ' and y=' + y + ' ' + hex; document.getElementById('ici').title=document.getElementById(myid).title; document.getElementById(myid).click(); } else if (hex.toUpperCase() != 'D0D0D0' && hex.toUpperCase() != 'FFFFFF' && hex.toUpperCase() != 'B3BCC0' && hex.toUpperCase() != 'BCBCBC') { if (document.getElementById('ici').title != origtitle) { gmenu('', document.getElementById('ici').title); } else { //document.getElementById('blastcol').click(); document.getElementById('myform').submit(); } } } else { document.getElementById('moix').value='' + x; document.getElementById('moiy').value='' + y; p = context.getImageData(x, y, 1, 1).data; hex = ('#' + ('000000' + rgbToHex(p[0], p[1], p[2])).slice(-6)).toUpperCase(); document.getElementById('moimode').value='mouseover'; myid=''; if (document.getElementById('myp').innerHTML.indexOf(hex) != -1) { myid=document.getElementById('myp').innerHTML.split(hex)[0].split(' id=\"')[eval(-1 + document.getElementById('myp').innerHTML.split(hex)[0].split(' id=\"').length)].split('\"')[0]; document.getElementById('ici').title=document.getElementById(myid).title; } else if (document.getElementById('myp').innerHTML.indexOf(hex.toLowerCase()) != -1) { myid=document.getElementById('myp').innerHTML.split(hex.toLowerCase())[0].split(' id=\"')[eval(-1 + document.getElementById('myp').innerHTML.split(hex.toLowerCase())[0].split(' id=\"').length)].split('\"')[0]; //document.title='x=' + x + ' and y=' + y + ' ' + hex; document.getElementById('ici').title=document.getElementById(myid).title; } else if (document.getElementById('ici').title == origtitle) { //document.getElementById('moblastcol').click(); document.getElementById('myformmo').submit(); } } } }

… 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 …

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 thechanged image_chartphp 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>'); } }
