Question

I have multiple URLs for users to download. The download should be triggered after they hit “Like” or post a “Tweet”. I have successfully setup the callback functions for both.

I wish to know how do I employ Javascript so that the multiple downloads are triggered simultaneously. One solution would be to use window.location, but that would trigger just single download. I can even do multiple window.open but the pop-up blocker would block this.

What other alternatives do I have for this situation?

What you can do is create a hidden iframe with the src of the file for each download, something like:

function download(url){ 
  var iframe = document.createElement("iframe"); 
  iframe.src = url;
  iframe.style.display = "none"; 
  document.body.appendChild(iframe); 
}
