Hi,

You need to check for keycode 13 which stands for Enter key.

HTML

<html>
	<head>
 	<script>
	function process(e)
		{
			var code = (e.keyCode ? e.keyCode : e.which);
			if(code == 13) { //Enter keycode
				alert("Sending your Message : " + document.getElementById('txt').value);
			}
		}
     </script>
 </head>
	<body>
	<textarea id="txt" cols="40" rows="5" onkeypress="process(event, this)">
	</textarea>
	</body>
</html>

Thx
