JavaScript Debugging in IE and FF

Posted by Kiran Mova on March 19, 2007

One of the Web 2.0 development challenges is debugging JavaScript. An IDE similar to eclipse/netbeans for JavaScript editing would be very helpful. I have heard “Venkman” is one such tool.

Most of the times, it is the simple JavaScript syntax errors that kill my development time. A missing semicolon or a api that the browser doesn’t support or an invalid object name. So, in my quest to find simple debugging tools that I can use within the browser, I found the following useful:

(a) For Firefox – Firebug

(b) For Internet Explorer – Script Debugger

Note: Firebug has several good features like inspecting the DOM, checking the CSS and profiling the javascript functions. I just love it. Script Debugger is certainly better than the native error messages that the IE displays. But before installing it reading this article might help.
