jQuery KeyDown Event

There will be scenarios which require to capture KeyDown event and execute some business logic. Here is one generic function I uses to accomplish this task.

    function CheckKey(e) {
        var keynum;
        if (window.event) // IE
        {
            keynum = e.keyCode;
        }
        else if (e.which) // Netscape/Firefox/Opera
        {
            keynum = e.which;
        }
        if (keynum == 8) {
           //Example: If backspace clear id
           $('#employeeid').val('');
        }
    }

Usage

   <input id="txtEmployee" onkeydown="CheckKey(event);" />
