this is actually a bug in IE (tested in IE8 with compatibility mode on) that should be covered by jQuery.

document.getElementById("someTextInput").value = null

incorrectly assigns a string "null" as opposed to what happens in non-substandard browsers (ie an empty string is assigned). This behavior should be standardized when calling

Yep I've come across the same issue. It'd be nice if jQuery could cover this quirk ;) Thx!

Test script:

<script src="jquery.js"></script>
$(document).ready(function() {
    alert($('#test').val() === "null");
<input type="hidden" id="test" value="" />
