requestFileSystem ok on Chrome, but undefined on Safari7 and mobile Chrome/Safari

Question

I'm trying to test the HTML5 FileReader API FileReader.readAsDataURL(file) on mobile but I'm running into problems. It works fine in desktop Chrome, but fails in Safari and mobile Chrome/Safari

I'm using this line: window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem // window.requestFileSystem is undefined on Safari and mobile

Is there a trick or a setting that I am not using?

Answer 1

This API is deprecated. Look at this article by Eric Bidelman:

Also look at compatibility at:
