Q966 How can I dynamically alter the maxlength property of a text form field?

Only in Internet Explorer 4+:

<form name="myForm">
<input type="text" name="myField" maxlength="10">
</form>

<script language="JavaScript"><!--
if (document.all)
    document.myForm.myField.maxLength = 5;
//--></script>
