Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

1、下载安装指令

npm install mj-tree-structure --save  

2、功能介绍

本插件主要有两个功能。
功能一:扁平结构的数据转化成树形结构的数据,关键点在于扁平结构的数据必须有一个字段存储其父级id
更能二:树形结构的数据转化成扁平结构的数据。

3、函数方法介绍

扁平结构数据转为树形结构数据的方法

函数的参数:treelization(list = [], parentId = 'parentId', key = 'children')
|参数名|描述|是否必须|
|--:|:--|:--:|
|list|数据源,必须是数组对象||
|parentId|父级id父级id必须与源数据的某个id值相等||
|key|存放子级数据的字段名称,也就是子级名称||


树形结构数据转为扁平结构数据的方法

函数的参数:delayering(arr = [], configure = [], key)
|参数名|描述|是否必须|
|--:|:--|:--:|
|arr|数据源,必须是数组对象||
|configure|存放数据字段,就是把需要获取的字段放到此数组中,必须保证这些字段在源数据中都存在,否则抛出异常||
|key|子级属性名,如果不传或传入的值在源数据中匹配不上,则返回源数据,并且源数据的第一级添加此属性,值为undefined||

4、调用方式

CDN引入

<script src="./node_modules/mj-tree-structure/index.js"></script>

<script>
    let { treelization, delayering } = treeStructure;
    
    // 扁平结构数据转为树形结构数据的方法
    console.log(treelization(arr, 'parentId', 'children'));

    // 树形结构数据转为扁平结构数据的方法
    console.log(delayering(arr, configure, 'children'));
</script>

vue引入

import { treelization, delayering } from "mj-tree-structure";
// let { treelization, delayering } = require("mj-tree-structure");

export default {
    name: "treeStructure",
    data() {
        return {};
    },
    mounted() {
        // 扁平结构数据转为树形结构数据的方法
        console.log(treelization(arr, 'parentId', 'children'));

        // 树形结构数据转为扁平结构数据的方法
        console.log(delayering(arr, configure, 'children'));
    },

    methods: {},
};
