Preserved Topic: what is window.onerror=null? (Page 1 of 1)

Anybody know what "window.onerror=null" line is for. I have seen this line in sone of Ozones pages.

Is this for IE4, so it doesn't pop up with the error popup?

Yes, you've got it right. It defines what to do when the "onerror" event occurs. So for any errors that happen in "window", do "null" or absolutely nothing. This line should only be used once you are absolutely sure you are done debugging your code!

This comes in handy when you are caching a bunch of mouseover images. This will kill the error messages if someone tries to mouseover before the images are done caching.

FYI.
