Error-logging for javascript on client side

Question

My project which contains a lot of pages with forms. This is a backend of banking CRM system, so any error during working process is to be captured and investigated. On the server side we have enhanced java exceptions system, but if error occurs on client side - javascript the only info we now get is an js-error window in IE or sometimes a screenshot of page made by advanced user.

Javascript code contains both Jquery-powered UI extensions and hard-coded inline event handlers and functions.

So I am asking whether any approach for capturing js-errors of any kind could be used? some additional library or something that could give me a stacktrace like firebug in Mozilla or web-console in Chrome?

Answer 1

http://exceptionhub.com Should to the trick. http://errorception.com/ Does not provide as much information for debugging, but also seems nice.

proxino don't seem to know what they are doing, they where incuding a complete jQuery in their logger code to log onerror events last time i checked. I wouldn't trust a service that has so little grasp of client side JavaScript to log my JavaScript errors.
