jQuery File Download is a cross server platform compatible jQuery plugin that allows for an Ajax-like file download experience that isn't normally possible using the web.

###Demo (of this exact source): http://jqueryfiledownload.apphb.com/

###Source here: https://github.com/johnculviner/jquery.fileDownload/blob/master/src/Scripts/jquery.fileDownload.js

###Targeting pretty modern browser(s)? This might be a better solution to your problem https://github.com/eligrey/FileSaver.js/

Requirements

• jQuery 1.6+

Common questions and answers

• Q: I need to send in custom headers. How do I do that?
  • Unfortunately since this plugin uses an iframe and not AJAX you cannot send in custom headers. If you really need to do this and are willing to accept a more narrow range of browser support this might be a better solution to your problem https://github.com/eligrey/FileSaver.js/
• Q: It doesn't work!?
  • Try out the demo and make sure you are doing exactly what it is doing: http://jqueryfiledownload.apphb.com/ If the demo doesn't work in your browser you have defintely found a bug and us know!
  • Due to iframe security restrictions you must serve up the file from the same domain you see in the address bar

Supported and tested browsers

• Internet Explorer 6+ - Works fine for standard use cases except in < IE9 JavaScript access to the failed response HTML doesn't (and can't) work reliably due to browser iframe constraints.
• Firefox 11+ - reasonably sure it will work on earlier versions
• Chrome 17+ - reasonably sure it will work on earlier versions
• iOS 5.0+ - reasonably sure it will work on earlier versions
• Android 4.0+ - non-GET requests do not work due to a long-standing bug in the Android browser. This is handled 'gracefully' with a message to the user.
