了jQuery找出HREF TD類下

Question

NEW_URL：

<td class="posts column-posts"><a href="edit.php?tshowcase-categories=ops&amp;post_type=tshowcase">2</a></td> 

OLD_URL：

<span class="view"><a href="https://blog.company.com/team/tshowcase-categories/ops/">View</a></span> 

我想以取代NEW_URL舊的URL ..

var new_url = $("td.column-posts").find("a").attr('href'); 
$("span.view").find("a").attr('href',new_url) 

我不能獲取new_url的值。

PLease help。由於

下面是完整的結構NEW_URL：

<tbody id="the-list" data-wp-lists="list:tag"> 
    <tr id="tag-7" class="alternate"> 
     <td class="posts column-posts"><a href="edit.php?tshowcase-categories=ops&amp;post_type=tshowcase">1</a></td> 
    </tr> 
</tbody> 

Answer 1

你可以這樣做，只是使IDS的鏈接：

$('#2').attr('href', $('#1').attr('href')); 

這裏是小提琴。 http://jsfiddle.net/Goodluck/PasNk/1/

Answer 2

如果只有一個td帶班column-posts

var new_url = $("td.column-posts a").attr('href'); 
$("span.view a").attr('href',new_url) 

如果有多個.column-posts TD，那麼你必須在each寫這樣

$("td.column-posts a").each(function(){ 
    $("span.view a").attr('href',new_url) //you have to map each span to each a 
}) 

Answer 3

附上表內TBODY標籤

<table> 
    <tbody id="the-list" data-wp-lists="list:tag"> 
     <tr id="tag-7" class="alternate"> 
      <td class="posts column-posts"><a href="edit.php?tshowcase-categories=ops&amp;post_type=tshowcase">1</a> 
      </td> 
     </tr> 
    </tbody> 
</table>
