jquery操作checkbox

[不通]

<div class="con-left">
  <div class="inputList" id = "app_list">
                <ul>
                    <li><input name='module' type="checkbox" value='app1'><span>APP名称</span> </li>
                    <li><input name='module' type="checkbox" value='app1'><span>APP名称</span> </li>
                    <li><input name='module' type="checkbox" value='app1'><span>APP名称</span> </li>
                    <li><input name='module' type="checkbox" value='app1'><span>APP名称</span> </li>
                </ul>
   </div>
 </div>      
 <div class="con-right">
            <h3>已选APP</h3>
            <div class="app-sel">
                <ul>
                    <li><input type="checkbox"><span>APP名称</span> </li>
                    <li><input type="checkbox"><span>APP名称</span> </li>
                    <li><input type="checkbox"><span>APP名称</span> </li>
                    <li><input type="checkbox"><span>APP名称</span> </li>
                </ul>
            </div>
    </div>

将前面APP列表中勾选的app动态显示到后面这个列表中，用jquery实现。

$(':checkbox').change(function(){$(this).parent().appendTo(this.checked?'.con-right ul':'#app_list ul')})
