title: File upload fails in IE 11 using FileUpload.js file
body: <p>I have a page where we upload files. I'm using <a href="https://github.com/blueimp/jQuery-File-Upload" rel="nofollow noreferrer">FileUpload.js</a> file for upload feature. I also a box for drag and drop for the files, everything works great in Chrome, Firefox and Edge but in IE 11, when I try to drag and drop the file in the box, I get this error:</p>
  
  <blockquote>
    <p>Unable to get property 'Value' of undefined or null reference</p>
  </blockquote>
  
  <p>I'm calling fileupload function like this</p>
  
  <pre><code>     $('#fileupload').fileupload({
                    maxChunkSize: 10000000,
                    maxFileSize: 2147483648,
                    autoUpload: true,
                    dropZone: $('#dragAndDropHandler')
                });
  </code></pre>
  
  <p>The HTML code is below - </p>
  
  <pre><code> &lt;div id="fileupload"&gt;
        &lt;div class="fileupload-buttonbar"&gt;
          &lt;label class="fileinput-button" style="background-color:#dddddd" &gt;
            &lt;span class="addfile" style="font-size:larger;font-weight:300;" &gt;Add files...&lt;/span&gt;
            &lt;input id="file" type="file" name="files[]" multiple onchange="setButtons(this)" /&gt;
          &lt;/label&gt;
            &lt;label style="color:black"&gt;CTRL + Click to select multiple files&lt;/label&gt;
  
        &lt;/div&gt;
        &lt;div class="fileupload-content" &gt;
            &lt;div id="dragAndDropHandler"&gt;&lt;span&gt;Drag &amp;amp; Drop Files Here&lt;/span&gt;&lt;/div&gt;
          &lt;table class="files"&gt;&lt;/table&gt;
          &lt;div class="fileupload-progressbar"&gt;&lt;/div&gt;
        &lt;/div&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>I tried to pass the <code>datatype: 'application/json'</code> and <code>dataType: 'text/plain'</code> it didn't work. </p>
  
  <p>I tried to implement this <a href="https://stackoverflow.com/questions/8814068/jquery-file-upload-ie-done-callback-data-result-issue">answer</a> but that didn't work. </p>
