title: On form submit, check size of files ready to be uploaded?
body: <p>I have a form which can have multiple file inputs (one file per input, not multi select).</p>
  
  <p>When I submit the form, how do I get an array of all <code>input[type="file"]</code> contents and use FileReader to look at the file sizes before they are uploaded, and prevent it if any of the files is too large?</p>
  
  <pre><code>$('#MyForm').submit(function() {
  
  });
  </code></pre>
  
  <p>I can't figure this out at all from what limited FileReader documentation I can find. Or not get it to work, anyway...</p>
