Hi there, this is my first post!

I'm having a problem with a javascript that works in IE but not in Firefox. I'm working with c# and asp.net. The script is to set the focus to a particular asp image button on the page when the user hit's the 'enter' key. here is the script:

Code:

function onkey()  {         
     if (window.event.keyCode==13) {                  
     document.getElementById("but_update").focus();         
     }     
}

And then in the form tag, I put

Code:

<form id="form1" method="post" runat="server" onkeydown="onkey();">

Now all this works in IE, but not in Firefox. Any idea why?

If you look at the Javascript console for Firefox it says it's not getting the window.event.. pass the event to the function:

HTML Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

	<head>
		<meta http-equiv="content-type" content="text/html;charset=iso-8859-1">
		<title>Untitled Page</title>
		<script type="text/javascript"><!--
function onkey(e)  {      
     if (e.keyCode==13) {                  
     document.getElementById("but_update").focus();         
     }     
}
//-->
</script>
	</head>

	<body bgcolor="#ffffff">
		<form id="FormName" action="" method="get" name="FormName">
			<input type="text" name="textfieldName" size="24" onkeypress="onkey(event); return false;"><input id="but_update" type="image" name="but_update" src="" alt="" height="50" width="50">
		</form>
		<p></p>
	</body>

</html>

Does that work in IE? (I'm on a Mac)

Try this instead.

Code:

var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;
	if (keyCode == 13) 
		document.getElementById("but_update").focus();
