How do I get the value for an input in firefox?

[tibberous]

I have an input, <input name="x">. I need to refer to the value on x. In Internet Explorer, it is x.value. How do I do it in Firefox?

The best practice in [b]both[/b] browsers is to specifically refer to that form element from the document level, then use [i]value[/i]. So, let's say your [b]form name[/b] is "myForm" and your element is named "x" as you show. You would need to reference it like so:
[code]
myValue = document.myForm.x.value;
[/code]

Hope this helps.

give your input an id the same as it's name:
[code]<input name="x" id="x"> [/code]
then you can refer to it like this:
[code]myValue = document.getElementById('x').value;[/code]
--the getElementById() is old and highly cross browser compatable

Actually, the "best best" way it to go through the elements collection of the form.

fenway, is that defining what I suggested above, or is it another approach entirely? If the latter, could you give a sample?

Thx.

Sorry, I mean:

[code]myValue = document.forms['myForm'].elements['x'].value;
[/code]

Ah, yes, you're probably right on that one.
