Jquery-根据表行类更改表单元格值

我有一张表显示了不同地点的营业时间,看起来有点像下面的结构;

<table class="tblServices">
 <tbody>
   <tr class="name loc1">
    <td class="name">loc1</td>
    <td class=""tcDayTimes">9-5</td>
    <td class="tcDayTimes">9-5</td>
   </tr>
   <tr class="name loc2">
    <td class="name">loc1</td>
    <td class="tcDayTimes">9-5</td>
    <td class="tcDayTimes">9-5</td>
   </tr>
 </tbody>
</table>

           <script type="text/javascript">
                    $('.tblServices > tbody > tr.loc2').each(
        $('td.tcDayTimes').html("24 hours")

有人能就我哪里出错提供一些建议吗?

提前谢谢
