title: Get JSON from another (php) file using pure javascript?
body: <p>I'm new to javascript. I have a php file that lists all the files in a directory. I want to call that file and get the json array that it echos using only javascript. I know jquery can do it... but this is the only thing I need to do. Its not worth learning jquery for it nor do I want to bloat my page with a library I'm only going to use for this one thing. </p>
