4 years later and still no window.onerror. I'll add yet another note that this feature is hugely valuable to web application developers who rely on it to be notified of client errors. Like others we have implemented a logging system to collect information on errors that our users encounter, and have found it invaluable. No, window.onerror as it is implemented in FF and IE is not the best, or "right" solution. But it's infinitely better than no solution. Until window.onerror is implemented in Webkit, we can't recommend Chrome and Safari to our users, even though we support them and would otherwise prefer them. 

It makes little sense to me to plow ahead with a raft of new HTML5 features while this basic piece of infrastructure is missing. There's no way I'm going to implement new functionality that is only supported in Webkit if I can't get error reporting short of littering my code with try/catch blocks.

It's been a year since Eric's comment that it wasn't valuable, and that has been refuted by many developers who absolutely do get a lot of value from it. And it's been 4 years since this deficiency was reported. Please, somebody tackle this!
