How to save the JavaScript errors in file

Question

Need a solution for saving log of JavaScript errors. For automated testing any site with support popular web browsers (IE, FF, Chrome).

Answer 1

The simple/best way to do :)

In simple steps:

1. Write a JavaScript error trapping code.
2. Add Ajax request/response module to send the trapped error to your server.
3. at the server store your Javascript errors to a log/database.
4. If needed, provide a functionality to access the log remotely.

Logging to a file on client-side has limitations:

1. Supported only by IE (using ActiveX Objects)
2. Obviously, files are stores on client side. Not at the server.
