jQuery 查找并列出特定 DIV 中 UL 内的所有 LI 元素

jQuery Find and List all LI elements within a UL within a specific DIV(jQuery 查找并列出特定 DIV 中 UL 内的所有 LI 元素)

问题描述

我有 3 列 UL，每个动态 UL 容器可以有 0-9 个 LI 容器(最终更多).我所有的 LI 元素都有一个属性rel"，我试图最终找到该属性并将其用于该父 DIV 中所有 LI 元素的其他内容.我最终确实想找到更多基于每个但不是最起码的 rel.. 任何想法我可以如何使用 jQuery 实现这一目标?示例:

I have 3 Columns of ULs each a Dynamic UL container that can have anywhere from 0-9 LI containers (eventually more). All my LI elements have an attribute "rel" which I am trying to ultimately find that attribute and use it for something else on all LI elements within that parent DIV. I do eventually want to find more based on each but for not the very least the rel.. Any Ideas how I can achieve that with jQuery? Example:

<ul id="column1">
   <li rel="1">Info</li>
   <li rel="2">Info</li>
   <li rel="3">Info</li>
</ul>
<ul id="column2">
   <li rel="4">Info</li>
   <li rel="5">Info</li>
   <li rel="6">Info</li>
</ul>
<ul id="column3">
   <li rel="7">Info</li>
   <li rel="8">Info</li>
   <li rel="9">Info</li>
</ul>

这些元素也是可排序的.因此，当我获得它们的列表时，我还想按照它们从每列的顶部到底部找到它们的顺序来保持它们.

these elements are all sortable as well. So when I get a list of them I want to also keep them in the order they were found from top to bottom of each column.

我已经尝试过 find()、parent() 和类似的方法，也许我处理错了.但它仍然值得一提，以帮助提出一个想法

I have tried find(), parent(), and similar, maybe I am approaching it wrong. But its still worth mentioning to help come up with an idea

推荐答案

你在想这样的事情吗?

$('ul li').each(function(i)
{
   $(this).attr('rel'); // This is your rel value
});
