AFAIK, only javascript-aware browser would interpret:

<script type='text/javascript'><!--
...
//--></script>

markup, and others would skip that code gracefully. So, I usually try
to generate javascript neutral pages which I improve with code
responsible to hide superfluous elements:

<form name='myform' ...>
...
<input id='myform_submit' class='inputbutton' type='submit' value='Go' />
<script type='text/javascript'><!--
document.getElementById('myform_submit').style.display = 'none';
//--></script>
</form>

I was in fact suggesting to re-use the same kind of trick I already
plugged into Cookbook.OptionMenu ;)
