<div class="lidiv">
<img src="../../images/head.jpg " class="liimg" />
<input name="checkbox" type="checkbox">
<div class="lidiv2">张三</div>
</div>
</li>
<li class="mui-table-view-cell mui-checkbox mui-left" style="height: 55px;">

<input name="checkbox" type="checkbox" >
<div class="lidiv2">张三</div>
</div>
</li>
