jQuery插件简单实现方法

(function($){  $.fn.extend({   myFunk: function() {    // 此处必须返回jQuery对象   return $();   },   myPunk: function() {    return this.addClass('punked')       .bind('click', function(){     alert('You were punked!');    });   }  }); })(jQuery);

$('.select').myFunk(); $('.select').myPunk();
