Can’t debug into a Javascript file. Error “No Disassembly Available” or “This breakpoint will not currently be hit. No symbols have been loaded for this document”

Ever put a break point in visual Studio 2010 on a .js file to get this?

This breakpoint will not currently be hit. No symbols have been loaded for this document.”

Then you decide to user the ‘debugger;’ statement. But then Visual Studio gives this error: “no disassembly available“.

You are probably loading your .js file dynamically. If you are, remove (or comment out) where you are loading and load it with an explicit script tag.

example: I was loading the script file like this:

<script src="<%=Url.StaticContent("/MyApplication/Scripts/views/script.js")%>" type="text/javascript" ></script>

I just commented out that line and hard coded the script file like this:

<script src="http://localhost/MyApplication/Scripts/views/script.js" type="text/javascript"></script>

Now I am able to user the debugger; statement AND able to put a break point in Visual Studio.
