For automated testing reasons I want to detect if the browser has encountered JavaScript errors for a page. The type of things that would cause the red numbers in the bottom right in Firebug or yellow warning icon in the Internet Explorer status bar. These JS errors could come from any one of a large numbers of scripts.

How in JavaScript can I detect these browser errors? Cross browser solutions prefered, but hey, I'll take anything!

As a bonus it would also be great to know the script that caused the error.
