In the question Why will Visual Studio 2005 not debug my javascript? I learned that debugging is possible in Visual Studio 2005 but you have to start debugging your application and then press CTRL-ALT-N to open the Script Explorer to set break points, etc.
However, even with the following simple code, when I press CTRL-ALT-N, the Script Explorer window is totally blank. According to all the articles I have found on the subject, it should have e.g. in my case "main.js" (I imagine it is like debugging in Firebug) but it is blank.
What else do I have to do to Visual Studio 2005 so that the Script Explorer shows my running javascript files?

javascript/main.js:
function test() {
document.write("this is from javascript code2");
}
function doIt(element) {
alert("This is the javascript function2.");
}

Try attaching your Visual Studio to MSIE via Debug > Attach to process (not sure if it is there in VS2005, look around).
When attaching to process make sure that you check script option.
-
The easiest way to get started is:
- Open IE7
- Goto the menu Internet Options > Advanced
- Uncheck "Disable script debugging"
To add a break point in a javascript add "debugger;" in your code. Open a page that references that script in IE7, and a popup will come up asking you if you want to debug your script in Visual Studio
<script type="text/javascript"> debugger; // put your code here </script>
