Is doesn't need to have an id you can also use a class name or something.

document.forms works only on IE and not on firefox, always use

document.getElementById( )

One thing that can cause this error too is that your javascript is placed below the form.

Check this out, javascript is interpreted before the end of the page loading, so if your form is placed after it, it will try to access your form before the browser have displayed id, thus the "no action" effect...

Either place your javascript after the form, or use a function that will be called upon the document.onLoad trigger.

In Firefax you can use:

var = document.<formname>.<elementname>.value to get the contents of an elements

<form name="myform">
<input name="input1" type="text" size="25" value="123"
<submit..... etc etc

var=document.myform.input1.value

var becomes 123 unless you type something else in....

Hi,
Thought I would post a follow up to the problem with firefox and javascript form submits.
I have found a way around it: You must return false; after the statement.

i.e: <button type="submit" onclick="{document.forms[0].submit(); this.disabled=true; return false;}">

This now works in Firefox aswell as IE! Hope this helps

Hi, i'm new and I just want to add a small scenario that you didn't mentioned here.

I was having the same problem that Firefox didn't submit the form.

Just for the record: Make sure none of our buttons, or fields is called "submit" because it will cause cause the function to "disapear"
