:nth-child
概述
匹配其父元素下的第N个子或奇偶元素
:eq(index) 匹配选择器指定序列的元素，而这个将为每一个父元素匹配子元素。
:nth-child从1开始的，而:eq()是从0算起的！可以使用:<br>nth-child(even)<br>:nth-child(odd)<br>:nth-child(3n)<br>:nth-child(2)<br>:nth-child(3n+1)<br>:nth-child(3n+2)
参数
indexNumberV1.1.4
要匹配元素的序号，从1开始
示例
描述:
在每个 ul 查找第 2 个li
HTML 代码:
<ul> <li>John</li> <li>Karl</li> <li>Brandon</li> </ul> <ul> <li>Glen</li> <li>Tane</li> <li>Ralph</li> </ul>
jQuery 代码:
$("ul li:nth-child(2)")结果:
[ <li>Karl</li>, <li>Tane</li> ]
