    How to capture keyCode in FireFox?

    Hi,

    I need to capture Enter key (keyCode==13) in an designMode enabled iframe of my chat sending virtual textbox. it's a wysiwyg posting. However I have the following code working fine in IE7 but not working in FireFox.

    Can Anybody please tell me how can I reffer to the keyCode in firefox in this example:

    Code:
    <body onLoad= Starta()>
<script>
function Starta() {
	iF=document.getElementById('rtoIFrame0').contentWindow.document;
	iF.onkeypress = cK;
	return true;
}
function cK(event) {
	if (document.getElementById('rtoIFrame0').contentWindow.event.keyCode){ 
		k = document.getElementById('rtoIFrame0').contentWindow.event.keyCode; // Works on IE
	}
	else if (document.getElementById('rtoIFrame0').contentWindow.e.which){
		k = document.getElementById('rtoIFrame0').contentWindow.e.which; // dos not Work on FireFox

	}
	if(k==13){
		alert(k);
		return false;
	}
	return true;
}
</script>
<iframe id=rtoIFrame0></iframe>

      You may need charCode instead. The method of obtaining the event is not correct. See this post.

          Hi acoder,

          That was a nice script. However I tried to make it work in my special code but I didn't succeed. I can't reffer to the object by window.event once the object is located in an iframe.

          The following part works on IE:
          Code:
          if (document.getElementById('rtoIFrame0').contentWind ow.event.keyCode){ 
k = document.getElementById('rtoIFrame0').contentWindo  w.event.keyCode;
}
          Please just let me know what exactly should I write instead the following part to make it work on firefox too.
          Code:
          else if (document.getElementById('rtoIFrame0').contentWind ow.e.which){
k = document.getElementById('rtoIFrame0').contentWindo w.e.which;
          Thank You!

              A simple
              [CODE=javascript]k = event.keyCode;[/CODE] will be enough here.
