OS and Software > Webmasters and Developers > Opening a file download dialog from a JavaScript function.

in the HEAD section:

<script type="text/javascipt">
function startDownload()
{
var url='http://server/folder/file.ext';  
window.open(url,'Download');
}
</script>
 

in BODY

<script type="text/javascipt">
setTimeout("startDownload()",5000); //starts download after 5 seconds
</script>
 

or if you have just 1 download location you can combine the 2 in the body:

<script type="text/javascipt">
setTimeout("window.open('http://server/folder/file.ext','Download')",5000); 
</script>
 

Edit: I wouldn't worry so much about the 0.01% that are paranoid and turn off javascript... But *do* provide a link in case a popup blocker kills the download.
