Removing form elements (submit inputs)

[Cain2000]

I'm using the following code to remove submit inputs after they have been clicked to stop double form processing.

gg=false;
function di(r)
{
 for (i=0;i < r.elements.length;i++)
 { if (r.elements[i].type=='submit')
    r.elements[i].style.visibility='hidden';
 }
 if(gg==false)
 {
  gg=true;
  return true;
 }
 else
  return false;
}

function grabit()
{
 for(i=0;i < document.forms.length;i++)
  document.forms[i].onsubmit = function() {return di(this);};
}

I don't really know very much about js, but i think that i am supposed to name the forms which i wish it to work on, as "r".

The problem is, what if i want every submit input on a page to dissappear, but they are in different forms? I have tried naming them all as "r" but only the submit inputs inside the form that i click an inout from, will dissappear.

Thanks in advance for any help, and please correct me if i have gone totally wrong with my understanding of the above code.

rough e.g.

function prvntDblSbmt(obj) {
	
	var frmInputs = obj.getElementsByTagName('input');
	for (var i = 0, tInput; tInput = frmInputs[i]; i++) {
		if (tInput.type == 'submit') { tInput.disabled = true; }
	}
	
}

<form action="./" method="post" onsubmit="prvntDblSbmt(this)">
	…
	<input type="submit" value="Submit" />
	…
</form>
