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.

When using trying to debug with Visual Studio and programming using .NET, you get a Visual Studio dialog that says “There is no source code available for the current location.”

1.The “Show Disassembly” button will be available. Click on it. You can step through the disassembly which does eventually take you into the code.
2. If you click “Show Disassembly” and then “Step Into” code (F11) just like you would have if the code window had loaded, you will see code mixed with other stuff.
3. When you see the code to debug, just right-click the window and choose “Go to Source Code” which opens up the code
