I’ve been wrestling with a bug in one of my modules for AIM Pages for_ever_, and just found a fix today. I created this well-intentioned module called code snippet that allows you to paste in markup and it’ll get inserted into the DOM. This is really just a stopgap to allow people to add stuff that a module doesn’t exist for yet. I never should have written it. Do you know how bad DOM support is in IE? It’s awful!\
The big problem is that people wanted/needed to insert script elements with inline script using the code snippet module, and I couldn’t figure out a good way to do it (ok, any way, good or otherwise). Just adding them to the DOM using innerHTML doesn’t work. IE won’t allow you to create a new script element and set the text content to the code.\
Today, I stumbled on a message board post that hints at the answer. What’s the answer?\
Create a new script element, and set the text property to the script content and then append it to the body. Voila, actual evaluated javascript! Here’s an example:

<code>var b=document.getElementsByTagName("body")[0];
var txt="function doIt(msg) {alert(msg)}";
var scr=document.createElement("script");
scr.setAttribute("type","text/javascript");
scr.text=txt;
b.appendChild(scr);</code>

Enjoy! Oh, and the fixed version of the module isn’t live yet. I’m letting the QA guys look at it first before I unleash it on an unsuspecting world.
