How can I log Javascript errors and report them without using Javascript?

My webapp currently employs a JS based error logging system for reporting JS error on the client side. The problem with logging your error using javascript is just that - we are using a technology to monitor problems in that same technology. Easily an error in the JS could prevent the logging from occuring.

I was wondering if anyone has an idea how we could log and report client side errors without relying on out own Javascript code.

thanks

Don't we always do that. Have you ever done error and exception handling in a language other than the one you're working with?

Use window.onerror callback. Will also catch syntax errors. Or try catching the error as @Squeegy suggests.

Unfortunately, I don't believe that is possible. You will have to use javascript in some form to catch and report the errors, whether it be sending an ajax request, or having users submit a form with the errors in a textbox.

Nope. But you can use a try / catch block to get out of javascript error that would otherwise stop execution.

try {
  stuff.that('raises').error();
} catch(e) {
  // send e via ajax
}
