Answer 1

Aptana Studio is a great Eclipse extension and can also debug Javascript

Answer 2

From the question, it sounds like you are trying to make an AJAX app that perhaps loads from local javascript + HTML.

That said, if it is OK to use Firefox as the web client, you might try Firebug. It is an excellent javascript debugger. It lets you do usual step / breakpoint things, inspect variables, and display the current page as a DOM model to help see what your jQuery (or Prototype, in my case) queries will find.

Answer 3

I've heard Firebug Lite could do this? That's probably not what you're looking for still.

Answer 4

I'm assuming you are creating WSH scripts based on your description. In order to debug WSH JavaScripts, start your script with wscript.exe /d path to WSH file after that, whenever an exception is going to occur, you are going to be presented with a choice to debug the script with Visual Studio or Microsoft Script Debugger (free). If you just want to step through the code start your script with wscript.exe /d /x path to WSH file this will cause an exception right at the begging of your script execution. More information here
