如何使用jQuery获取表格单元格值 [英] How to get a table cell value using jQuery

问题描述

我正在尝试使用jQuery为我无法控制的表获取td值。在这个网站上发布了一个很好的例子，但它引用了每个tr中的一列而不是多列。

我也没有表或行的id ...对于td只有 class = columndata 。

  $ （'#mytable tr'）。each（function（）{
 var customerId = $（this）.find（td）。eq（2）.html（）; 
} 
  

将获得固定tr的单个td？

这是我的表数据：

 < tr valign =top> 
< td class = columnactionvalign =center> 
< img src =../ images / spacer.gifwidth =1height =1/> 
< a href =javascript：void（0）;class =columnactionlinkonclick =return doAccept（'599577'，'1'，''，''）;alt =Accept> Accept< / a> 
< / td> 
< td class =columndata>消息< / td> 
< td class =columndata>测试< / td> 
 < td class =columndata >< / td> 
< td class =columndata>< / td> 
< td class =columndata> 04/09/2011 23:59< / td> 
< td class =columndata> 04/09/2011< / td> 
< td class =columndata> 05/12/2011 07:00< / td> 
< td class =columndata> 05/13/2011 07:00< / td> 
< td class =columndata>< / td> 
< td class =columndata> Doe，Jeffrey A.（xx）< / td> 
< td class =columndata> 913014405580< / td> 
< td class =columndata> Skip< / td> 
< td class =columndata> 04/09/2011 16:37< / td> 
< td class =columndata> C< / td> 
< td class =columndata> Doe，J< / td> 
< td class =columndata> 04/09/2011 16:37< / td> 
< td class =columndata> 04/09/2011 23:59< / td> 
< td class =columndata> 04/09/2011 16:34< / td> 
< / tr>

这是你需要的选择器：

  $（ '#mytable tbody tr td：nth-​​child（2）'）
  

I am trying to get the td values using jQuery for a table I have no control over. There is an excellent example posted on this site, but it references one column not multiple ones within each tr.

I also don't have an id for the table or rows... only a class=columndata for the td.

$('#mytable tr').each(function() {
    var customerId = $(this).find("td").eq(2).html();    
}

will get the single td of a fixed tr?

Here is my table data:

<tr valign="top">
    <td class="columnaction" valign="center">
        <img src="../images/spacer.gif" width="1" height="1" />
        <a href="javascript:void(0);" class="columnactionlink" onclick="return doAccept('599577', '1', '','');" alt="Accept">Accept</a>
    </td>
    <td class="columndata">Message</td>
    <td class="columndata">Test</td>
    <td class="columndata"></td>
    <td class="columndata"></td>
    <td class="columndata">04/09/2011 23:59</td>
    <td class="columndata">04/09/2011</td>
    <td class="columndata">05/12/2011 07:00</td>
    <td class="columndata">05/13/2011 07:00</td>
    <td class="columndata"></td>
    <td class="columndata">Doe, Jeffrey A. (xx)</td>
    <td class="columndata">913014405580</td>
    <td class="columndata">Skip</td>
    <td class="columndata">04/09/2011 16:37</td>
    <td class="columndata">C</td>
    <td class="columndata">Doe,J</td>
    <td class="columndata">04/09/2011 16:37</td>
    <td class="columndata">04/09/2011 23:59</td>
    <td class="columndata">04/09/2011 16:34</td>
</tr>
