any clean ways to download files like html5 download attribute

Question

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.

Answer 1

There is Downloadify, which generates and force downloads files with Flash. There's also a demo available.

Or you could download the file using XHttpRequest ($.get in jQuery) and use data URIs.

Answer 2

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");
