Is there a way of terminating JavaScript code in it's tracks?

[littlejim84]

I've been doing lots of Googling and looking in my books, but can't seem to find a function that does this? I'm basically wanting to try some things out in other peoples code and I'm trying to find a way to terminate code dead in it's tracks where I want... Bit like the die() statement in PHP?

Many thanks.

You could always throw an Error if something goes wrong. The JavaScript will stop executing after this. Is that what you want?

Example

// something went terrible wrong
throw new Error("Fatal error!");

Install Firebug, select the "script" tab and click in the left margin to set a breakpoint.

That's perfect... Thank you!

I'm on IE so I can't use the FireFox extention.

You can install Firefox. Seriously -- Developing Javascript on IE, is an uphill battle.

If you insist, you can use the IE script debugger.

Yes, I have FireFox... Its my favourite browser. It's just the projects I work on (in my team) have developed the whole thing to work just in IE so I kinda have to use that to debug... IE Script debugger? I'll check that out. Cheers!
