Auto-closing a popup with a file to download

Question

I have a file, named download.php, which contains a file to be downloaded, so it has the following headers (declared with PHP):

header(\"Content-Typ         


        

Answer 1

I have a somewhat different proposal, which worked fine in my case and does not have an arbitrary timeout:

var newwindow = window.open("http://example.com/download.php");
newwindow.focus();
newwindow.onblur = function() {newwindow.close(); };

When finishing the download the new window will eventually unfocus and close.
