        #tab-02, #tab-03 { display:none;} 
     
     
        $(document).ready(function () { 
            $('.tabs span').mouseover(function () {

              $('.tabs div').hide();
              //查找.tabs span同辈元素span 后面紧邻的同辈元素div显示
              $(this).siblings('span').removeClass('active').end().addClass('active').next('div').show(); 
            }); 
        });
