    <script type="text/javascript" src="../js/jquery-3.3.1.min.js"></script>
    <script type="text/javascript">
        $(function(){
            // $("div").find("p").css("border","1px solid red");
            //div下查找p,addBack()回溯找到div,.css()对两者同时添加样式
            // $("div").find("p").addBack().css("border","1px solid red");
            // 注意:对于筛选或查找后的元素,要加入先前所选元素时,使用addBack()方法会很有效,符合链式设计原则

            //返回jQuery对象,为p元素添加边框,同时为div添加背景
            $("div").find("p").css("border","1px solid red").end().css("background","#ff0");


        });    </script></head><body>
