在div中包装子元素的范围 [英] Wrapping range of children elements in a div

问题描述

我正在尝试将div中的一系列子元素包装起来，以便在组中操作它们;试图将每个小组定位在不同的地方。场景是我有一个随机生成 li 标签的列表，无论出现多少，我需要分别操作每一组十个。

I'm trying to wrap a range of children elements in div in order to manipulate them in groups; trying to position each group in a different place. The scenario is that I have a list randomly generating li tags and no matter how many appear I need every set of ten to be manipulated separately.

为了解决这个问题，我使用了一个书面清单：

To figure this out I'm using a written out list:

$("ul li ul li:nth-child(n+11)").wrapAll("<span class='shift' />");

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="access">
  <div class="menu">
    <ul>
      <li>
        <p>Hello</p>
        <ul>
          <li>Stuff</li>
          <li>Stuff</li>
          <li>Stuff</li>
          <li>Stuff</li>
          <li>Stuff</li>
          <li>Stuff</li>
          <li>Stuff</li>
          <li>Stuff</li>
          <li>Stuff</li>
          <li>Stuff</li>
          <li>Stuff2</li>
          <li>Stuff2</li>
          <li>Stuff2</li>
          <li>Stuff2</li>
          <li>Stuff2</li>
          <li>Stuff2</li>
          <li>Stuff2</li>
          <li>Stuff2</li>
          <li>Stuff2</li>
          <li>Stuff2</li>
          <li>Stuff3</li>
          <li>Stuff3</li>
          <li>Stuff3</li>
          <li>Stuff3</li>
          <li>Stuff3</li>
          <li>Stuff3</li>
          <li>Stuff3</li>
          <li>Stuff3</li>
          <li>Stuff3</li>
          <li>Stuff3</li>

        </ul>
      </li>
    </ul>
  </div>
</div>

但这不是我当然需要。

这是我现在正在处理的代码。

Here's the code I'm working on now.

var count = $("ul li ul li").length;
for(var c = 11; c<=count;c+=10){
$("ul li ul li:nth-child(n+"+c+")").wrapAll("<span class='shift' />");
}

这种方法有效但它会创建移位类的嵌套实例。

This kind of works but it creates nested instances of the shift class.

我需要单独的包装器div。如果我要编写代码，那就是：

I need separate wrapper divs. If I was to make up code it would be:

 $("ul li ul li:nth-child("+c+"<n<"+(c+10)+")").wrapAll("<span class='shift' />");

但显然这不起作用。其他人之前做过类似的事。一直没有成功搜索。

But obviously that won't work. Anyone else do something like this before. Been searching a bit with no success.

推荐答案

你可以试试。切片方法：

// note: different from nth-child, slice is 0-based position
$("ul li ul li").slice(c, c+10).wrapAll("<span class='shift' />");
