title: Save content dynamically with Javascript
body: <p>I want to allow my clients to be able to have a save-dialogue come up to save data that I've stored in Javascript.  I can't direct them to an existing file because you can't modify the file system directly with Javascript.<br>
  Is it possible to send data directly to be saved (of course through a save-dialogue. Otherwise, it would be a crazy exploit).  I'm trying to make it so my users can create content on my site and be able to download it.</p>
