title: How to remove inputmask when an ajax form is submitted as FromData?
body: <p>It happens that my ajax form has a file upload input, and therefore I have to submit it with an <code>FormData</code> instead of a simple <code>.serialize()</code>. Then I found the <code>autoUnmask</code> on my jquery.inputmask no long effective.</p>
  
  <p>Here is the example:
  <a href="http://jsfiddle.net/btqtnumL/1/" rel="nofollow">http://jsfiddle.net/btqtnumL/1/</a></p>
  
  <p>When the form is submitted, the result from <code>.serialize()</code> has a value with input mask removed. But the result from <code>FormData()</code> still shows the mask.</p>
  
  <blockquote>
    <p>Content-Disposition: form-data; name="cost"</p>
    
    <p>1,000</p>
  </blockquote>
  
  <p>How can we remove the mask in this case?</p>
