Clone a file input element in Javascript

Question

I have a file input element that needs to be cloned after the user has browsed and selected a file to upload. I started by using obj.cloneNode() and everything worked fine,

Answer 1

Editing the file form field is a security risk and thus is disabled on most browsers and should be disabled on firefox. It is not a good idea to rely on this feature. Imagine if somebody was able, using javascript, to change a hidden file upload field to, lets say,

c:\Users\Person\Documents\Finances

Or

C:\Users\Person\AppData\Microsoft\Outlook.pst
