jQuery的：如何找到它是当前元素正在添加前2个元素的元素 [英] jquery: how to find an element which is comming 2 elements before current element

问题描述

我有一个标记，看起来是这样的：

i have a markup which look like this:

<h3>Paragraf3-dummytext</h3>
<p>
<a name="paragraf3">
Quisque id odio. Praesent venenatis metus at tortor pulvinar varius. Lorem ipsum dolor sit 
</a>
</p>

我想要做的是找到所有'A'与'名称'属性标签，并找到对于锚H3标签;即时通讯试图做这样的：

what i want to do is to find all 'a' tags with 'name' attribute and find the 'h3' tag for that anchor; im trying to do it like this:

var paragraf = [];
var paragrafheading = [];
$('a[name]').each(function() {
paragraf.push($(this).attr('name'));
paragrafheading.push($(this).prev().text());

但它不工作becouse有围绕着文本的p标签任何建议，将不胜感激谢谢

but it does not work becouse there is a 'p' tag around the text. Any suggestions would be appreciated. Thanks

推荐答案

您可以做的：

paragrafheading.push($(this).parent().prev().text());

如果总有不在身边的一个段落，或者你不知道锚多少家长可以H3的面前，你可以做一些事情是这样的：

If there's not always paragraph around the a, or you don't know how many parents the anchor can have before the h3, you can do something like this:

paragrafheading.push($(this).closest('> h3').find('> h3').text());
