jQuery从列中的隐藏输入中获取价值

问题描述：

我有以下HTML表格...

I have got the following HTML table...

<table>
  <thead>
    <tr>
      <th>Nr.</th>
      <th>Name</th>
      <th>Info</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>1</td>
      <td>Laura</td>
      <td><input type="hidden" value="1"><a href="#" class="info">Info</a></td>
    </tr>
    <tr>
      <td>2</td>
      <td>Sabrina</td>
      <td><input type="hidden" value="2"><a href="#" class="info">Info</a></td>
    </tr>
  </tbody>
</table>

当单击链接时，如何使用jQuery获得隐藏输入字段的值?

How can I get with jQuery the value of the hidden input field, when the link is clicked?

$(".info").click(function() {
  // Here I need to find out the value...
});

答

操作方法如下:

$(".info").click(function(e) {
  //just in case, will be useful if your href is anything other than #
  e.preventDefault();
  alert($(this).prev('input[type="hidden"]').val());
});

prev方法将搜索上一个元素，这就是您的input[hidden]所在的位置.

prev method will search for the previous element, which is where your input[hidden] is.

及其href而不是hre，位于<a/>标记中.

And its href, not hre, in the <a/> tags.
