title: Fine-Uploader: Getting the original triggered element (clicked, or dropped)
body: <p>I have one fineuploader instance, and installed a number of drop targets and buttons.</p>
  
  <p>The way I'm arranging this is similar to Google Drive's upload feature, where there is one centralized upload box that lists all the files in progress, and on completion, I would like to do some DOM manipulation on the original triggered elements (drop target, or button), and put a preview, and some details in it.</p>
  
  <p>To do the DOM manipulation, I would like to get the original triggered element.</p>
  
  <p>To make this more clear, here is how I initialized the drag and drop element:</p>
  
  <pre><code>    $('.drop-zone').fineUploaderDnd({
          classes: {
              dropActive: "cssClassToAddToDropZoneOnEnter"
          }
      })
      .on('processingDroppedFiles', function(event) {
          //TODO: display some sort of a "processing" or spinner graphic
      })
      .on('processingDroppedFilesComplete', function(event, files, dropTarget) {
          //TODO: hide spinner/processing graphic
  
          $gallery_upload.fineUploaderS3('addFiles', files); //this submits the dropped files to Fine Uploader
      });
  </code></pre>
  
  <p>Here is how I initialized the button:</p>
  
  <pre><code>$gallery_upload.fineUploaderS3({
      ...
  
      extraButtons: [{
          element: $(".pdf-button"),
          validation: {
              allowedExtensions: ["jpg"]
          }
      }],
      ...
  </code></pre>
  
  <p>I was reading the documentation on fineuploader, but don't find any variables that explain about the possibilities of this.</p>
  
  <p>I was wondering if this is possible, and if so, please kindly give me some assistance.</p>
  
  <p>Your help is greatly appreciated!</p>
  
  <p>Cheers,
  Thomas</p>
  
  <p>==============================================</p>
  
  <p>So from the start, I shouldn't have used the separate module: 
      $('.drop-zone').fineUploaderDnd({...</p>
  
  <p>Now, I have modified my code for Dnd to the following, and then, Ray's solution will work nicely with it:</p>
  
  <pre><code>$gallery_upload.fineUploaderS3({
      dragAndDrop: {
          extraDropzones: [ $('.drop-zone') ]
      },
      ...
  </code></pre>
