Dan, Meropi Petraki,
Just filter out ESC in key down event.
The ASCII code for ESC is 27, so in key down event
check if keyCode has this value. If yes, make
event.returnValue = false.
Example:
<html>
<head>
<script language="javascript">
function onKeyDown() {
if (event.keyCode == 27) {
event.returnValue = false;
}
} // onKeyDown
</script>
</head>
<body>
<form name="aForm">
<input type="text" name="aText" onkeydown = "onKeyDown()">
</form>
</body
</html>
