Strange Symphonies The best way to predict the future is to invent it

Browser window event Loader

Web 2.0 is high like a dog on rabies, and one of its supporting pillars is a dormant technology that is now being put to some good use. You basically need JavaScript kung-fu else, chances are you might lose out in the game!

I myself despise JavaScript for its awkward behavior on multiple browsers, but with the increasing usage of JavaScript, it appears that these browsers are finally working together which is great! One of the weapons in my arsenal which makes JavaScript development more fun is the prototype libraries! Its almost like Ruby, but for JavaScript! Yes, crude as it may sound, but if you don't mind my cussing, its damn diddly awesome.

While hacking, I had a jumble of JavaScript libraries that had dependencies on one another, but functions which initialize stuff on the browser loading, had dependencies on one another. Yes, it was some weird hack. But the webs straight forward manner made this more difficult. Sometimes I needed code that was later down in the page to be loaded first, etc. Hopefully you get the point now. Well nonetheless, I construed together this beast! You need the Prototype libraries for this.

function addLoadEvent(func, weight) {
if (typeof weight != 'number')
weight = 0;

if (typeof addLoadEvent.funcs[weight] == 'undefined')
addLoadEvent.funcs[weight] = $A(new Array);

addLoadEvent.funcs[weight].push(func);
}

addLoadEvent.funcs = $A(new Array);

window.onload = function() {
addLoadEvent.funcs.compact().each( function(array) {
array.each( function(func) {
if (typeof func == 'function')
func();
});
});
}

So what can you do with this? Say your source code was as such...

// File 1
function load_markers() {...}
addLoadEvent(load_markers, 1);
...

// File 2
function load_google_maps() {...}
addLoadEvent(load_google_maps, 0);
...

This could possibly happen because of the design of the CMS/Framework and it loads a certain library first (which it shouldnt), but you have no absolute control of it.

If some of you may have noticed, it was inspired after looking at the Drupal source code, well I was having troubles using the Drupal framework and resorted to this to get things done .
