Joel,
just a further note…don’t leave out the “onreadystatechange” part of the IE specific code or the solution will fail in some edge cases and in iframes.

By using “timeouts” alone it is not reliable enough and flickering may be annoying.

This trick is currently used by most libraries out there, some of them failed the full implementation and they have had partial success.

Google Ajax JS API is the only library having that trick fully implemented in current release. jQuery, ExtJS and Prototype will follow shortly, there are already patches written for all of them.

I am interested in your results.

Hi Joel,

Firstly, your site was of really great help to me.

It seems that your implementation for IE is the same as with prototype. We were encountering some problems with this way specifically when we load the scripts dynamically. I have searched the internet regarding this prototype’s error and found this http://dev.rubyonrails.org/ticket/10942

So for the update i think you should wrap the code like this

if(document.readyState != “complete”) {
document.write(”
“);
var deferScript = document.getElementById(“__ie_onload”);
if (deferScript) {
deferScript.onreadystatechange = function() {
if (this.readyState == “complete”) {
initializeDelegate();
}
};
}
}

Hey Diego,

Great! Thanks for providing the cross-browser link. I’ll definitely check it out and maybe update my fix with the new code.

Hi Joel,
you only found my IE specific function, my take to a cross-browser solution is located here:

http://javascript.nwbox.com/ContentLoaded/

The answer to “why linking other people’s code” is because they all did their part of the job, I only found the trick for IE which is only one component of the complete solution.

Currently all browsers have a “DOMContentLoaded” event, except IE.

The “IEContentLoaded” trick should fit perfectly with your needs, also I am not a .NET expert, but really this is the only thing that works on IE. In my current code there is a fallback for IFRAMES too.

Hope it helps, cheers
