Re: Implementation of DOMContentLoaded failing when no assets

by Diego Perini :: Rate this Message:

Here is a small test that should output this sequence:

* readystatechange
* iecontentloaded
* load

both in the body and in the window status bar (if enabled).

The results with current jQuery and no assets is instead:

* readystatechange
* load
* iecontentloaded

thus the "onload" function fires before the ".ready()" method.

Substitute square brackets with angle brackets in this code:

[script type="text/javascript" src="jquery-1.2.3.js.orig"][/script]
[script type="text/javascript"]
/* IEContentLoaded test (jQuery implementation) */
$(document).ready(function () {
document.body.innerHTML += ' * iecontentloaded[br /]';
status += ' * iecontentloaded';
});
/* Event "onready..." still available to applications */
document.onreadystatechange = function () {
if (this.readyState == 'complete') {
document.body.innerHTML += ' * ' + event.type + '[br /]';
status += ' * ' + event.type;
}
};
/* Event "onload" still available to applications */
window.onload = function () {
document.body.innerHTML += ' * ' + event.type + '[br /]';
status += ' * ' + event.type;
};
[/script]

I already know where the problem lies, I only have to setup
a patch for current code, hopefully including also the other
expected behavior of ".ready()" being called by default
at startup. This is for the "Lazy Loading" approach to
work consistently (want to use "isReady()" later on).
