Question

So I have two forms, both have a file type input field and I tried

$('.inputfield1').change(function(){
   var file = $(this).val();
   $('.inputfield2').val(file);
});

but then it doesn’t get copied properly and firebug complains about “Security Error” in the error console

what did I do wrong and how can I properly copy the value of a file input field

by the way, the destination form has a target that is set to an iframe (not a different domain)

You can’t move the value of one file input to another. Instead, clone the input, place the clone where the original is, and move the original into the hidden form.

$(".inputfield1").change(function(){
  var $this = $(this), $clone = $this.clone();
  $this.after($clone).appendTo(hiddenform);
});
