                                            <div class="clear">
                                            </div>
                                            <div class="plbottom">
                                                <a onclick="">展开</a>&nbsp;&nbsp;<a href="#">收起</a></div>
                                        </div>
      <div class="navplcenter">
                                          
                                            <div class="clear">
                                            </div>
                                            <div class="plbottom">
                                                <a onclick="">展开</a>&nbsp;&nbsp;<a href="#">收起</a></div>
                                        </div>在点击每一行的“展开”的时候，让 <div class="navplcenter"> 改变CLASS为     <div class="navplcenter2">
这个怎么做呢？

  1.   

    也可以写在<head>里面，用jquery或者js都可以，不过不要跟楼上这么回答。
      

  2.   

    onclick="this.parentNode.parentNode.className='navplcenter2';"
      

  3.   

    onclick="this.GrandFatherNode.className='navplcenter2';"

  4.   

    jsonclick="this.parentNode.parentNode.className='navplcenter2';"
    jqueryonclick="$(this).parent().parent().attr("class","navplcenter2");
