Just making jQuery Plugins--no big deal.

;(function($){
   $(document).ready(function(){
    var dropItLikesItsHot =  $("div.dropzone").dropZone();
    Dropzone.autoDiscover = false;
  });

  var markupButton = "<button class=\"dropzone-del\"><i class=\"fa fa-remove\"></i> Remove File</button>";
  $.fn.extend({
    dropZone: function() {
      return new Dropzone($(this)[0],
        {
          init: function (){
            var $that = $(this); // this jQuery Plugin Obj
            var _that = this; // this Dropzone Obj

            //dropZone addFile Event
            _that.on("addedfile", function(file) {
              var removeButton = Dropzone.createElement(markupButton);
              removeButton.addEventListener("click", function(e){
                e.preventDefault();
                _that.removeFile(file);
                //del from server sessions/filesystem
                $that.delFromServer(file.name);
              });
              //on this file obj append a button
              file.previewElement.appendChild(removeButton);

            })
          },

          url: "/embroidery-quote/ajax",
          paramName: "file"
      });
    },

    delFromServer: function(key) {
      $.get("/embroidery-quote/ajax", {'do': 'remove_artwork', 'key': key});
    }
  });
})(jQuery);
