如何获取链接内容（innerHTML）并将其添加到其他链接中作为标题

Question

I have div content for posts. The posts exist within a <li> . What I would like to do is take the post title from the link on the item-title class and add it as a title in the link on item-thumbnail class.

This is the html base.

<div class='section' id='popular_posts'>
<div class='widget PopularPosts' id='PopularPosts1'>
<h2>Popular Posts</h2>
<div class='widget-content popular-posts'>
<ul>
<li>
<div class='item-content'>
<div class='item-thumbnail'>

<div class='item-title'><a href='http://test-abdelghafour.blogspot.com/2013/04/blog-post.html'>the first post title</a></div>

this is the jQuery code that i use.

$('#popular_posts .item-title a').each(function(){
var pptitle = $('#popular_posts .item-title a').text();
$('.item-thumbnail a').each(function(){
$(this).attr('title', pptitle);
});
});

the result that i want to get for each link.

Answer 1

The var pptitle = $('#popular_posts .item-title a').text(); call inside the each loop will select the same text node each loop iteration. And the second each loop will set that text to every .item-thumbnail .

This should do what you want:

$("#popular_posts li").each(function(){
  var pptitle = $(this).find(".item-title a").text();
  $(this).find(".item-thumbnail a").attr("title", pptitle);
});
