One thing unfortunate about working with JavaScript is the need to debug on major browsers. So, I had to spend some time looking into compatibility issue on IE 7. Fortunately, I found this blog and it was very helpful. So, I installed Visual Web Developer 2008 Express Edition beta 2 and was able to quickly identify the root cause, which was in the difference of data structure representation.
I was disappointed that FireFox and IE would construct different data structure representations. For example, in the array that I am worked with, the data were in index 0 for IE and 1 for Firefox. I also had to use target sub-element within an array element for Firefox to find the data I was looking for, while I don’t needed to use it for IE. As a result, I had to find an IE detection code to add special conditional processing code.

When using Firefox browser, try the FF extension, Firebug. It does some excellent Javascript debugging, such as step in and step out.
Hi Richard,
Thanks for pointing out Firebug. I actually use it all the time on FF. The reason I had to use Visual Web Developer 2008 is because of IE 7.
The error messages that IE7 provides sometime give little insight as to what the problem really is. I really like the Error Console provided with FireFox.
I use Splinetech Javascript Debugger, and I’m quite happy with it. It supports IE only though.
