Yes, you can define a function to handle any errors:<br />
<br />
window.onerror=handleError<wbr />;<br />
<br />
and then, if you want to do nothing just leave it blank<br />
<br />
function handleError() {}<br />

You have to put a 'return true' on your function.<br />
<br />
function handleError {return true;} <br />

I noticed that Microsoft didn't support the standard Javascript command: window.onerror=null.<br />
<br />
By using the command, the Javascript enabled browser will *NOT* display any form of Javascript error if any shoulf occur. &nbsp;So, if a variable or function is not defined yet, the annoying default Javascript error window will not pop up and report it thanks to that onerror command.<br />
<br />
The command works beautifully in Netscape, of course, but not in Internet Explorer 4 and most likely not in Internet Explorer 3. &nbsp;Is there anything i can do to prevent the JS error window from popping up in MS Internet explorer?<br />
<br />
Thanks a million.<br />

Window.Onerror=NULL for Internet Explorer

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
