Javascript KeyCode Reference table for Event Handling

The post explains Keyboard event handling using javascript.Javascript events are used to capture user keystrokes. Below is a table of key codes for the keys on a multimedia keyboard. If this table is inconsistent with your own findings, please let me know.

Java Script Code to Find Key code

<script language="JavaScript">
document.onkeydown = checkKeycode
function checkKeycode(e) {
var keycode;
if (window.event) keycode = window.event.keyCode;
else if (e) keycode = e.which;
alert("keycode: " + keycode);
