title: how to exclude certain input fields when injecting form object into FormData constructor?
body: <pre><code>  $('#rewardForm').submit(function(e) {
          e.preventDefault()
          var formData = new FormData($('input[name!="files[]"]', $(this)[0]))
          console.log(formData);;
    })
  </code></pre>
  
  <p>I would like to exclude the input field with name equals to "files[]". And then inject the form object into FormData(). What should I do?</p>
