如何讓這個js在按鈕標籤上而不是在錨上工作？

這是我發現的一個插件，名爲dropit.js如何讓這個js在按鈕標籤上而不是在錨上工作？

我試圖在按鈕標籤上使用它，但它不起作用，只有一個標籤。

    var methods = { 

     init : function(options) { 
      this.dropit.settings = $.extend({}, this.dropit.defaults, options); 
      return this.each(function() { 
       var $el = $(this), 
        el = this, 
        settings = $.fn.dropit.settings;

將觸發元件更改爲按鈕。
