any clean ways to download files like html5 download attribute

Question

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+

• Safari 5.1.9+
• Opera 12.1

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