besides not working (onchange will not fire until focus leaves the field)
its pretty non w3c compliant code, try:
<html>
<head>
<script language="javascript">
function displayLength(e) {
document.getElementById('inputLength').innerHTML =
e.value.length;
}
</script>
</head>
<body>
<form id="myForm" runat="server">
<asp:textbox id="input" runat="server"
onkeyup="displayLength(this)" /><br>
<asp:label id="inputLength" runat="server" />
</form>
</body>
</html>
