结合使用jQuery中的选择器功能

Question

I need to select the parent element of the current element, then going to the next one and selecting the anchor tag inside that element. So for example, my DOM looks like this:

-td
  - span  (my element)
- td
- a

So what am doing is:

$(this).parent().next().("a") //doesn't work

How can I combine the next() function with a selector like a or select something by its class or id?

I couldn't find anything on jQuery documentation for that.

Answer 1

你可以用这个

$(this).parent().next().find("a") //it work

Answer 2

With your current set-up, using this works:

$(this).parent().next("a");

By the way, your markup is wrong . You cannot have a <a> as a sibling of <td> , which means, either the <td> is not inside <tr> or <a> is inside <tr> , which is wrong . So I assume your markup is similar to this:

<td>
  <span></span>
</td>
<td>
  <!-- -->
</td>
<a></a>

So, if you are putting it like this ( valid markup ):

<td>
  <span></span>
</td>
<td>
  <!-- -->
</td>
<td>
  <a></a>
</td>

You need to use:

$(this).parent().next().children("a");
