for example I have button element, the click event is attached to id in XXX.js file (I don't know the file name) , and I have many .js files. I want to debug the button click but how can I figure out where to set breakpoint if i don't know where button click function is ? is there any way to set breakpoint on element ( I'm using firebug, if it's impossible on firebug and possible for any other add-on please tell)
I'm using EXT sencha to add eventhandlers
I would check out this plugin. That will help you find what file/where the bound event lives. Then you can debug from there. http://www.sprymedia.co.uk/article/Visual+Event+2
