自动排序方法以附加功能 [英] auto sort method to append function

问题描述

我有一个动态列表，用户可以向ul添加li(项目).他们可以选择1,2和3级.目前，它们都附加到ul，没有排序功能.我希望级别1始终在插入时位于第一个，级别2随之出现，然后是级别3，将其视为优先级.例如，我在一个级别为2的列表中有4个项目，那么当一个级别为1的新项目进来时，它不会追加到最后一个项目上，而是追加到第一个项目上.

I've dynamical list that user can add li (items) to a ul. They can choose level 1,2 and 3.. for now they all append to ul, with no sorting function. I want the level 1 always on the 1st when been inserted, level 2 will come along and then followed by level 3, think of it like priority. for example I've 4 item in a list with level 2, then when a new item with level 1 come in, it doesn't append on the last item, but the 1st.

我想知道我是否必须自己编写排序函数，thx

I'm wondering must I write the sort function on my own, thx

推荐答案

执行此操作的方法是将属性附加到特定级别的li元素上，例如:

A method to do this will be attach attribute to li elements at specific level like:

<ul>
    <li class="level1">this is level 1</li>
    <li class="level1">this is level 1</li>
    <li class="level1">this is level 1</li>
    <li class="level2">this is level 2</li>
    <li class="level2">this is level 2</li>
    <li class="level3">this is level 3</li>
    <li class="level3">this is level 3</li>
</ul>

然后在适当的级别插入
