是要取到li对象吗？$("#ctl00_cphContentBody_rptCard_ctl04_liPopup")
var elemstr = $("#ctl00_cphContentBody_rptCard_ctl04_liPopup").parent().html();
问题详细如下:<div id="abcd">
   <li id='1'>
      <div class="11"></div>
    </li>
    <li id='2'>
      <div class="22"></div>
    </li>
    <li id='3'>
      <div class="33"></div>
    </li>
</div>已知22,要得到
    <li id='2'>
      <div class="22"></div>
    </li>
var elemstr = $(".22").parent().parent().html();

<div id="abcd">
<ul>
<li id='1'>
<div class="11"></div>
</li>
<li id='2'>
<div class="22"></div>
</li>
<li id='3'>
<div class="33"></div>
</li>
</ul>
</div><script>
jQuery.fn.outerHTML = function(s) {
return (s)
? this.before(s).remove()
: jQuery("<p>").append(this.eq(0).clone()).html();
}
alert($('.22').parent().outerHTML());
</script>
</body>
</html>
问题还是提得不详细,不好意思,应该如下:<ul id="Thetag">
   <li tag="1" >
      <div>1</div>
   </li>
   <li tag="2" >
      <div>2</div>
   </li>
   <li tag="3" >
      <div>3</div>
   </li>
</ul>想对调下 2 和 3 的位置, 让结果如下<ul id="Thetag">
   <li tag="1" >
      <div>1</div>
   </li>
   <li tag="3" >
      <div>3</div>
   </li>
   <li tag="2" >
      <div>2</div>
   </li>
</ul>
不好意思,一开始没表达清楚, 就是想将指定id的li前移或后移

文本框里输入 li tag 的取值
<body>
<ul id="Thetag">
<li tag="1" >
<div>1</div>
</li>
<li tag="2" >
<div>2</div>
</li>
<li tag="3" >
<div>3</div>
</li>
</ul>
<script>
$(document).ready(function(){
$('#Thetag li[tag="2"]').appendTo($('#Thetag')); //进行移动操作
});
<script>
