任何干净的方式来下载像html5下载属性的文件 [英] any clean ways to download files like html5 download attribute

问题描述

我完全清楚在javascript / jQuery中下载文件方面有很多争论（和解决方案），例如 iFrame ， jQueryPlugin 。但是，我对HTML5中的下载属性< a> 等内置设施更感兴趣。问题是它支持，它支持所有现代浏览器。

  var blob = new Blob（[Hello，world！]，{type：text / plain; charset = utf-8}）; 
 saveAs（blob，hello world.txt）; 
  

I am fully aware that there are many debates(and solutions) out there in terms of downloading files in javascript/jQuery, such as iFrame, jQueryPlugin. However, I am more interested in a kind of built-in facilities like download attribute of <a> in HTML5. The problem is that it supports a couple of browsers:

That is how I want to download files, without creating frames or using any plugins. The questions is are there any other cross browser built-in(say, easier or cleaner) ways to do it?

• Internet Explorer 8+
• Firefox 19+
• Chrome 17+
• Safari 5.1.9+
• Opera 12.1

解决方案

You might want to try FileSaver.js which has support for all modern browsers.

var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
saveAs(blob, "hello world.txt");
