Code for handling keyboard event in Internet Explorer <html> <head> <script type="text/javascript"> function keyDownListener() { var key; key = window.event.keyCode; alert('Key Code ' + key); document.keyForm.textBox.value = ""; return false; } </script> </head> <body> <form name="keyForm" id="keyform"> <input type="text" name="textBox" id="textBox" size="20" oncontextmenu="return false" onkeydown="return keyDownListener()" /> </form> </body> </html> #2.

A reference serves as an alternative name or alias to an object. We cannot define reference to a reference type, but can make a reference to any other data type.
