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 …


function dcdomc() {
// <img data-onload="canvit(this);" onclick="if (atstart) { normalcall=false; ask(null); normalcall=true; atstart=false; } else { ask(event); }" title="Google Chart Image Chart " +="" cname="" '="" image="" ...="" to="" modify,="" please="" click'="" id="myvenn" width="455" height="350" data-style="display:block;width:455px;height:743px;background:url(//www.rjmprogramming.com.au/ITblog/455/350/?cht=map&chld=AU-NT%7CAU-NSW%7CAU-SA%7CNZ%7CIN&ufr=_4179574);background-size:cover;" src="//www.rjmprogramming.com.au/ITblog/455/350/?cht=map&chld=AU-NT%7CAU-NSW%7CAU-SA%7CNZ%7CIN&chco=B3BCC0|5781AE|FF0000|FFC726|885E80|518274|A3BCC0|4781AE|EF0000|EFC726|785E80|418274&ufr=_4179574" usemap="#mymap">

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

… 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 …
