我有一个页面，其中包含一个包含5列和多行的基本表。每列代表一个工作日，每一行代表菜单上的不同菜肴。我想创建一个只显示今天菜单的页面。
我对此表没有写访问权限。 （如果必要的话我可以要求网站管理员做一些修改）
对我来说，显示具有ID =“星期一”的所有东西似乎是合乎逻辑的，但我无法从中获得任何东西。
这是现有的表格：
<table cellpadding="4" class="weeklymenu" width="100%">

我修改了你的表以获得类并将表修剪为只有两行并使用jquery进行操作。
这是html
<table>
<tbody>
<tr ID="day">
<th class="monday" scope="col" width="20%">Monday</th>
<th class="tuesday" scope="col" width="20%">Tuesday</th>
<th class="wednesday" scope="col" width="20%">Wednesday</th>
<th class="thursday" scope="col" width="20%">Thursday</th>
<th class="friday" scope="col" width="20%">Friday</th>
</tr>
<tr ID="date">
<td class="monday" class="date" width="151">08/04/2013</td>
<td class="tuesday" class="date" width="179">09/04/2013</td>
<td class="wednesday" class="date" width="144">10/04/2013</td>
<td class="thursday" class="date" width="141">11/04/2013</td>
<td class="friday" class="date" width="152">12/04/2013</td>
</tr>
</tbody>
</table>
这是我用来获取数据的JavaScript。你可以使用多种条件随心所欲地做任何事情
var data = '';
$('.monday').each( function() {
data += $(this).html();
});
alert(data);
