An event handler assigned with DOM methods or otherwise via a script has
different behaviour than an event handler assigned in a tag.
Specifically, the event handler in the textarea tag for onkeypress receives the
event before the character is inserted and can be cancelled in time, whereas the
script-wise assigned handlers cannot prevent the character to be inserted.
example:
<html>
<head>
<title> New Document </title>
<script>
function initEventListeners() {
document.testForm.textArea2.onkeypress = limitC;
document.testForm.textArea3.addEventListener("keypress", limitC, false);
}
function limitC() {
return false;
}
</script>
</head>
<body onload="initEventListeners()">
<form name="testForm" action="testForm.html" method="GET">
<textarea id="textArea1" cols="40" rows="5" wrap="soft" onkeypress="return
limitC();"></textarea><br>
<textarea id="textArea2" cols="40" rows="5" wrap="soft"></textarea><br>
<textarea id="textArea3" cols="40" rows="5" wrap="soft"></textarea><br>
</form>
</body>
</html>

In the second text area if you press tab the focus is not changed, but in the
third text area it is working...
