When Firefox encounters the JavaScript API call: document.getElementById() it
returns a null for valid elements.

Reproducible: Always
Steps to Reproduce:
1. Save the HTML code below to a file on the file system.
2. Click on the menu options File -->Open File and select the above file
3. The reference to the hidden field should be valid yet it returns a null
Please note that the html below works fine under IE.

<html>
<body>
<form action="bla" />
<input type="hidden" name="control" value="false">
<script Language="JavaScript">
var element = document.getElementById('control');
alert('found the element: ' + element);
</script>

</form>
</body>
</html>


Actual Results:  
found the element: null

Expected Results:  
Under Internet Explorer the results are: found the elment: [object]
It doesnt work because the element has no id. That is what
document.getElementById is for. The fact that name is enough for IE shows that
its an IE bug.

Hi.
You are right on the technical side yet wrong from a business perspective.
I ran the same code with id instead of name and it works fine.
Yet there are countless sites using the getElementById() passing in the name 
as a parameter. Furterhmore, jakarta Struts does not generate an id tag for 
html controls. I think the correct approach is allowing the getElementById to 
take name.

This is actually a duplicate, so whatever you do, dont reopen it. Comment in the
other bug, but I doubt this will be considered, since its invalid.
