[转载]jquery :nth-child()选择器的简单应用 – 我是一个不入流的Coder. – 博客园.

今天项目中遇到过一个这样的问题,就是希望读出来的文章列表能够每隔五个加一个分割条,而不是每个都加。

通过网上咨询使用这个选择器便很容易的解决。特此记录一下。

下面是主要的代码

js脚本:

<script type=”text/JavaScript”>
$(document).ready(
function () {
//每隔五行给li加一个样式
$(‘.article_li li:nth-child(5n)’).addClass(‘liborder’);
$(‘.article_li li:last’).addClass(‘liborder’);
}
);
</script>

html代码:

<ul class=”article_li”>
<li>
<label class=”datename”>
<span>2010-06-12 08:37:59 </span>
</label>
<a href=”/a/xinwenzixun/caishuidongtai/20100612/2323.html”>物业税:长沙暂不试点物业 税:长沙暂不试点</a>
</li>
<li>
