How clone value input file

Question

How I can clone value attribute of file input field. Something like this:

<input type="file" id="field1"/>
<input type="file" id="field2"/>
<script>
$('#field2').val($('#field1').val());
</script>

Answer 1

I found solution of this problem:

<input type="file" id="field1"/>
<span id="field2_area"><input type="file" id="field2"/></span>
<script>
$('#field1').change(function(){
    var clone = $(this).clone();
    clone.attr('id', 'field2');
    $('#field2_area').html(clone);
});
</script>

Answer 2

If you are wanting them to stay the same when user interacts with them:

$(function(){
    $('#field1').on('keyup blur', function(){

            $('#field2').val($(this).val());

     }).blur();
});

Triggering the blur() on page load will do the same as code you already have

EDIT Just realized these are file fields... browser security limits what you can do with them
