attachEvent

[hunt00]

My attachEvent calls a character count function on key up and key down. It slows down IE dramatically, with using up 100% of my cpu.

Does anyone know how could i get over this?

Thanks!

Post your code - it could have some glaring errors in.

document.getElementById("test").contentWindow.document.attachEvent("onkeyup",charCounter);
document.getElementById ("test").contentWindow.document.attachEvent("keydown",charCounter);

I havn't seen your full code but im pretty sure you can just
document.attachEvent(someevent).

Seems like you using the document to go the an element to get the content window then the document. Are you using frames?

Also I don't see why this would slow down a broswer, would need to look at your site.

Also attachEvent is an IE only event model. So your script won't work cross browser...

Oh yah seems like your attaching the event every time they press a key, that will slow things down:<

Thanks very much, Dan, for your help and reminding! It is that i put it on a keypress, above on that calling this attachEvent makes everything slow down. yah, for the firefox, i am using addEventListener.

Have a great weekend!
