That documentation doesn't really help. What are the arguments that are passed to onerror? Is it an "event" object as normal? Or is onerror not a DOM-like event but just a function pointer? Can you addEventListener the error event, or is it only accessible from window.onerror as a callback? If it's a normal DOM event, what does its interface look like? I tried looking up this information on MSDN and in the Mozilla sources but came up mostly empty. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
