form input type=file per javascript

[flo]

hallo,

also soetwas in der art meine ich
<script type="text/javascript"><!--
function x() { return; }
var n=-1;
function fn() {
n++;
document.getElementById("mehr").firstChild.nodeValue =  document.getElementById("mehr").firstChild.nodeValue + ' <input type="file" name="file'+ n +'" />'+ n;
}
--></script>

<a href="javascript:x();fn();">link</a>
<div id="mehr">file</div>
