Find out which Key was pressed using jQuery

A user had a requirement to take actions on a page based on the KeyPressed. Here’s a simple script that you can do that and works cross-browser.

<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>Find KeyPressed</title>

    <script src="http://code.jquery.com/jquery-latest.js"
    type="text/javascript"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            $(this).bind('keypress', function(e) {
                var key = (e.keyCode ? e.keyCode : e.charCode);
                alert(key);                   
            });
        });
    </script>
</head>
<body>
<div>
</div>
</body>
</html>

You can also use ‘e.which’ instead of ‘e.charCode’. I have tested the code on IE7, Chrome and Firefox 3.
