Submit form using javascript on a link

[jc_gmk]

I've got a form that is submitted by a link rather than a submit button.

The following code works great with internet explorer but not firefox, any ideas?

<a href="#" onclick="return submititems(this.form);"><img src="content/images/submit.jpg" /></a>
	
<script type="text/javascript" language="javascript">		
function submititems(thisform) 
		{ 
		for (var q=0, e=this.orderqty.elements, i = e.length-1; i > -1; --i)
			{
			if (e[i].name && e[i].name=='qty[]' && !isNaN(+e[i].value))
				{
				q+= +e[i].value;
				}
			}
		if (q==0)
			{
			alert("you have not selected any products");
			}
		else
			{
			if (q==1)
				{
				if (confirm("add " +q+ " product to the shopping cart?")) 
					{ 
					document.orderqty.submit();
					}
				else
					{ 
					return false; 
					}
				}
			else
				{
				if (confirm("add " +q+ " products to the shopping cart?")) 
					{ 
					document.orderqty.submit();
					}
				else
					{ 
					return false; 
					}
				}
			}			 
		} 
	</script>

onclick="return submititems(this.form);">

is not valid. It should be something like document.forms[0] or document.getElementByIt('formID') or something to that effect.

Hope this helps.

how exactly do I change my code?
Do i literally change this.form for what you've suggested?

Sorry i'm fairly new to javascript.

Sorry, I should have been more specific in my last post. Yes, you change the part that I highlighted (this.form) to point to the actual form such as what I posted above.

Hope this helps.

I've now changed it to:

<a href="#" onclick="return submititems(document.getElementById('product_add'));">

and changed the id of the form to 'product_add'

Which again works fine with Internet Explorer but not firefox.

Also I presume you meant - document.getElementById?

Any other ideas?
