Copy input from text box to hidden field

[betheball]

I have a form that includes a input type="file" field for upload. Would it be possible in javascript to have the path from the that field be automatically copied to a hidden field? Of course, if the answer is "yes", the next question would be, how?

<form name="frm" action="">
<input type="file" name="fileUp1" onchange="this.form.copy1.value=this.value; alert(this.form.copy1.value);">
<input type="hidden" name="copy1">
</form>

Use the onchange event handler to copy the value to the hidden field

Absolutely perfect. Thanks!
