我有一个页面，其中有一个包含 5 列和几行的基本表格。每一列代表一个工作日，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。

我对此表没有写入权限。（如果有必要我可以要求网站管理员进行一些修改）

对我来说，显示所有具有 ID="monday" 的东西似乎是合乎逻辑的，但我无法从中得到任何东西。

这是现有的表：

<table cellpadding="4" class="weeklymenu" width="100%">
  <tbody>
    <tr ID="day">
      <th ID="monday" scope="col" width="20%">Monday</th>
      <th ID="tuesday" scope="col" width="20%">Tuesday</th>
      <th ID="wednesday" scope="col" width="20%">Wednesday</th>
      <th ID="thursday" scope="col" width="20%">Thursday</th>
      <th ID="friday" scope="col" width="20%">Friday</th>
    </tr>
    <tr ID="date">

我修改了您的表以包含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。你可以使用多个条件做任何你想做的事情

var data = '';
$('.monday').each( function() {
    data += $(this).html();
});
alert(data);
