title: File dialog from JavaScript *without* <input>
body: <p>I am adding file import functionality to an existing page.</p>
  
  <p>I want to do this using javascript and without modifying the page, ie. without adding the "input type="file" " tag, everyone seems to be talking about.</p>
  
  <p>I have added the button, now I want the event to show the file dialog, user to browse for file and javascript to submit file to server for validation.</p>
  
  <p>How do I do that? 
  Btw, main priority is opening file dialog, so no need for user or submitting part, if you don't know it.</p>
  
  <p>Thx</p>
