Multiple ids with getElementById();

Hi Developers!

I'm trying to get javascript to write html on a page when a link is clicked.

function updatetext(){

    var file = document.getElementById("file").value;

document.getElementById('updated').innerHTML = file;


<input id="file" value="text I want to write to the page" type="hidden">

<span id="updated">&nbsp;</span>

This works for an ID labeled "file" but I have multiple ID's like, file1, file2, file3...

I'm wondering if my onclick="updatetext()"; should have some argument like onclick="updatetext(1)"; but that doesn't seem to work. I'm not sure how to get the right input id from clicking on the link.

thanks in advance

try this,it may  may be resolve your problem
function updatetext(id){
    var file =document.getElementById("file" + id).value;
    document.getElementById('updated').innerHTML = file;

That should do it, if you want to do what I interpreted
