Chrome webkitRequestFileSystem and the file:// protocol

Question

It seems impossible to use the webkitRequestFileSystem method from a local file without some sort of debug switch being passed to Chrome when it's run. Is there a way to ask a user for permission to save a text file (one that they have requested anyway) that is generated by javascript in a locally run html app/file?

Kind of, as long as it is not too much data and you don't need to support older versions of IE. You can do it with a Data URI.

10000173 shows the technique, and 283956 has some answers on how you can't easily specify the filename that the browser chooses.

Unfortunately the data that needs to be exported will be quite significant in size most of the time. – Resist Design Apr 06 '12 at 02:23
