如何使用jquery用html包装每3个子div？

Question

可能重复:
在div中包含每3个div

首先,我知道我应该使用服务器端语言来实现这一点,而不是像jquery这样的客户端,但这不是重点,我只是想学习如何使用它来操纵html.继承人html:

<div class="items">
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="1.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 1</span></div></div>
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="2.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 2</span></div></div>
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="3.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 3</span></div></div>
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="4.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 4</span></div></div>
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="5.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 5</span></div></div>
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="6.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 6</span></div></div>
</div>

我希望能够每3包<divs>内的<div class="items">又一格:<div class="row"></div>.所以它最终是这样的:

<div class="items">
 <div class="row">  
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="1.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 1</span></div></div>
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="2.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 2</span></div></div>
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="3.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 3</span></div></div>
 </div>
 <div class="row">
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="4.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 4</span></div></div>
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="5.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 5</span></div></div>
  <div class="boxgrid"><span class="cushycms"><a href="#"><img src="6.jpg" alt=""/></a></span><div class="cover"><span class="film_title">Title 6</span></div></div>
 </div>
</div>  

我如何用jquery的选择器完成这个？我以为我可以使用类似的东西:

$("div.items:nth-child(3n)").wrap('<div class="row"></div>');

但这不起作用.有什么想法吗？

Answer 1

我认为你真正想要的是1到3之间的div范围,而不只是包裹第三个div,是吗？

要获得范围,您需要使用jquery切片.
