Re: [Jmol-developers] Opening a new 'hidden' window seems to break JSmol applet

[Robert H. <ha...@st...>]

Just one more note on this....

JSmol uses a hidden form on a page to submit just this sort of thing (a
file download using "attachment") as well. I had forgotten that. While the
browser does temporarily display a blank page, that page does not persist
after the file is sent.

>From jsmol.php:

...
ob_start();
 if ($imagedata != "") {
    $output = $imagedata;
    header('Content-Type: '.$contentType);
    if ($filename != "") {
      header('Content-Description: File Transfer');
        header("Content-Disposition: attachment; filename=\"$filename\"");
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    }
...
 header('Last-Modified: '.date('r'));
 header('Accept-Ranges: bytes');
 header('Content-Length: '.strlen($output));
 print($output);
ob_end_flush();
