Thanks for the JS debugger.

I am evaluating it and i can only get it to stop in JS code embedded in the HTML file i started with or the scripts listed in the head. We use Dojo and most of the JS code gets downloaded on demand: scripts are downloaded by Dojo and eval()-ed.

Is this debugger supposed to debug this JS code too?

I am currently trying to change Dojo to emit includes <script></script> for the scripts Dojo imports/requires/downloads.

I am having some success but i am breaking the internal state of the widget manager in Dojo.

Do you guys already have a solution to this?

Thanks
Nick

I figured out how to use something from Dojo to achieve this.

1) Include browser_debug.js after dojo.js

Code:

2) Call writeIncludes after the last dojo.require from the HTML file you debug.

Code:

dojo.hostenv.writeIncludes();

This sequence effectively overrides the default code loading mechanism in Dojo (see loadUri from browser_debug.js) and emits <script/> snippets in the head of the document thus convincing the browser to download the scripts itself. Using a smart technique this new loadUri includes the scripts in the correct order based on their dependencies.

Good luck
Nick
