Question

If I have a

<input id='uploadFile' type='file' /> 

tag, and a submit button, how do I determine, in IE6 (and above) if a file has been selected by the user.

In FF, I just do:

var selected = document.getElementById('uploadBox').files.length > 0; 

But that doesn’t work in IE.

Answer 1

This works in IE (and FF, I believe):

if(document.getElementById('uploadBox').value != '') {    // you have a file }
