35岁，对中国程序员来说是一个很沉重的年龄！

Js代码 

var accordion = {  

     init: function(){  

           var $container = $('#accordion');  

           $container.find('li:not(:first) .details').hide();  

           $container.find('li:first').addClass('active');  

           $container.on('click','li a',function(e){  

                  e.preventDefault();  

                  var $this = $(this).parents('li');  

                  if($this.hasClass('active')){  

                         if($('.details').is(':visible')) {  

                                $this.find('.details').slideUp();  

                         } else {  

                                $this.find('.details').slideDown();  

                         }  

                  } else {  

                         $container.find('li.active .details').slideUp();  

                         $container.find('li').removeClass('active');  

                         $this.addClass('active');  

                         $this.find('.details').slideDown();  

                  }  

           });  

     }  

};
