Jquery 之siblings()方法

     siblings()---------  Jquery遍历同级对象

    html 代码：

                   <div>

                       <ul>

                             <li>a</li>

                             <li>b</li>

                             <li>c</li>

                       </ul>

                   </div>

     js代码：

             $("ul li").bind("mouseover",function(){

                        $(this).addClass("current").siblings().removeClass('current');      //此li加上current类，而其它的同级的li除去current类
   
              });

           <div id="aaa">
               <p>1</p>
               <p>2</p>

               <h1>2</h1>
               <h2>22</h2>
              <div>abcdefg</div>
          </div>
          var curr = $("#aaa h1");
          curr.siblings(); //包括与p同级的所以元素：p, h1, h2, div
          如果带参数curr.siblings("p")那就只能取得到两个p
