jQuery查找并列出特定DIV内UL中的所有LI元素 [英] jQuery Find and List all LI elements within a UL within a specific DIV

问题描述

我有3个UL列，每个动态UL容器可以有0-9个LI容器（最终更多）的任何地方。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元素上的其他元素。我最终希望找到更多基于每个，但不是最不rel ..任何想法我可以实现与jQuery？示例：

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

这些元素也都是可排序的。所以，当我得到他们的名单，我想也保持他们从每一列的顶部到底部的顺序。

我已经尝试过find（），父母（）和类似的，也许我正在接近错误。但它仍然值得一提的帮助提出一个想法

解决方案

你在想这样的事情吗？ b
$ b $ $ $ $ $ $ $ $'$'$'$' rel'）; //这是你的rel值
}）;

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>

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.

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

解决方案

Are you thinking about something like this?

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