How can I capture/examine a keypress? Specifially want to detect user hitting F3

Thanks

Perhaps a keystroke for F + the number 3, but F3 doesn't have a keycode in JavaScript, taht I know of.

By 'F3' I mean Function Key 3.

Generally, how to I set a variable to the value of the key pressed?
thanks

You might be interested in http://www.infinitypages.com/research/keycode.htm, though as Jona said, I don't believe you can capture the F3 key...

I did this in IE, but you'll need more code for Netscape.


<script>
function daKIE() {
var str = "You pressed key #"+event.keyCode+"\n";
alert(String.fromCharCode(event.keyCode));
oDiv.innerHTML=event.keyCode +" = "+ String.fromCharCode(event.keyCode);
alert(str);
}
</script>
</head><body onKeyPress="daKIE()" onMouseDown="daKIE()"><div id="oDiv"></div></body></html>

Beat me to it. ;)

We're right, though, the F4 key returns "s." :p

F3 is code 114 but NS 7.1 triggers the Seach-this-page popup and IE opens the Search navframe on the left.

Guess I must first find a way to suppress a browsers's default handling of Function keys...if I can...will let you know if I figure it out.

Thanks to all of you.

I highly doubt you will be able to disable the browsers actions for the Function keys. And, even if you could, before doing things like that, you need to think if you should...
