How do I count dynamic elements by their ID 1

[LyndonOHRC]

Hi, I'm writing a form to scan an unknown number of barcode labels. The technique I’m trying is to use is to store the data in hidden input elements. To give them unique id’s I need to count how many have an id beginning with the string “CurrentValue“ so I can concatenate the count to the string I’m using for my id .

What I have so far:

[COLOR=red]//NextElement=count how many have an id beginning with the string “CurrentValue“[/color]

var NewHiddeninput=document.createElement("input");
NewHiddeninput.id='CurrentValue'+NextElement;
NewHiddeninput.type='Hidden';
NewHiddeninput.value=document.Scan.label1.value;
document.Scan.appendChild(NewHiddeninput);

Thanks

Lyndon

If you're building up the form youself, why not initialise a global variable to "1" and then increment it after each input you create, and use that to build the unique IDs?

Hope this helps,
