使用Javascript函数启动下载 [英] Initiate downloads with a Javascript function

问题描述

我有多个网址供用户下载。下载应在他们点击赞或发布推文后触发。我已经成功设置了两者的回调函数。

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.

我想知道如何使用Javascript以便同时触发多次下载。一种解决方案是使用 window.location ，但这只会触发单次下载。我甚至可以做多个 window.open 但是弹出窗口阻止程序会阻止这个。

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.

还有什么其他选择呢？我有这种情况吗？

What other alternatives do I have for this situation?

推荐答案

你可以做的是为每次下载创建一个隐藏的iframe文件的src，如：

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); 
}
