I googled and got the following codes on the Net.However, when I press a keyboard key,it is not displaying me an alert box. I want to get which character I have pressed in the alert box. How do I fix this?

<script type=text/javascript>



var charfield=document.getElementById(char)

charfield.onkeydown=function(e){

var e=window.event || e;

alert(e.keyCode);

}



</script>

</head>



<body id=char>



</body>

</html>

If you want to get the character typed, you must use the keypress event rather than the keydown event. Something like the following:

var charfield = document.getElementById(char);

charfield.onkeypress = function(e) {

    e = e || window.event;

    var charCode = (typeof e.which == number) ? e.which : e.keyCode;

    if (charCode > 0) {

        alert(Typed character:  + String.fromCharCode(charCode));

    }

};
