一. 调研
1.常见树状图 | 思维导图
-
echarts
https://echarts.apache.org/examples/zh/editor.html?c=tree-polyline -
gojs
https://gojs.net/latest/samples/decisionTree.html
https://balkan.app/OrgChartJS/Demos/RoyalFamilyTree
https://codepen.io/tutsplus/pen/MWedpoj -
有复选框的treeNode
https://devexpress.github.io/dotnet-eud/interface-elements-for-web/articles/tree-view/tree-view-nodes-checking.html
2.对比结果
拟采用的方法：
改造 jsmind 实现自定义的思维导图
Jsmind 的功能及使用见官方文档：
https://github.com/hizzgdev/jsmind/blob/master/docs/zh/index.md
二. 文件目录
1. public\jsmind.css
jsmind 插件自带的 css 文件，思维导图的样式文件。
2. public\jsmind.js
jsmind 插件自带的 js 文件，思维导图的逻辑实现。
3. public\mind.js
思维导图的数据和触发方法，数据挂载在 window 对象下，用于和 vue 框架中的内容交互。
4. src\components\minder\DataMind.vue
思维导图的业务调用组件，包括思维导图、标题栏和左上 tip 文字内容。
5. src\components\minder\Minder.vue
思维导图的核心组件，分为 5 种类型：defalut，check，label，label2，input，通过 type 传值配置对应样式。
！！！当然这只是我根据项目需求改造的几种样式，大家也可以自行阅读下面minder.vue、jsmind.css以及jsmind.js进行个性化改造。
三. 功能点实现
1.介绍
Jsmind的功能及使用见官方文档：
https://github.com/hizzgdev/jsmind/blob/master/docs/zh/index.md
本demo采用 vue3+typescript+vite 实现，核心功能在 src\components\minder\Minder.vue 文件中实现。
2.在 index.html 中引入 jsmind
如下图所示：
<link rel="stylesheet" href="/jsmind.css" />
<script type="text/javascript" src="/jsmind.js"></script>
3.页面中引入 Minder 组件
如下所示：
4.传入的数据结构，如下所示：
(window as any).mindData = {
id: "root",
topic: "根节点名字",
number: [88],
children: [
{
id: "easy",
topic: "规章制度",
children: [
{
id: "easy1", topic: "请休假制度" },
{
id: "easy2", topic: "考勤制度" },
],
},
{
id: "open",
topic: "岗位职责",
children: [
{
id: "open1",
topic: "人事部职责",
children: [
{
id: "open1-1", topic: "行政管理" },
{
id: "open1-2", topic: "人事管理" },
],
},
{
id: "open2",
topic: "信息部职责",
children: [
{
id: "open2-1", topic: "信息安全" },
{
id: "open2-2", topic: "信息排查" },
{
id: "open2-3", topic: "信息汇总" },
{
id: "open2-4", topic: "ERP" },
],
},
{
id: "open3",
topic: "生产车间",
children: [
{
id: "open3-1", topic: "安全制度" },
{
id: "open3-2", topic: "车间操作手册" },
],
},
],
},
{
id: "powerful",
topic: "员工福利",
number,
children: [
{
id: "powerful1", topic: "雪天", tip: "3366" },
{
id: "powerful2", topic: "年假", tip: "98999" },
{
id: "powerful3",
topic: "法定节假日",
number,
},
{
id: "powerful4", topic: "生日祝福" },
{
id: "powerful5",
topic: "成长与进步",
children: [{
id: "powerful5-1", topic: "员工培训" }],
},
],
},
],
};
其中，id，topic，children 的用法见官方文档，number 为定制化展示的数据部分，如下图所示：
当 type 为 label2 时，number 为数组，对应关系如下图所示：
- type 分为 5 种类型：default，check，label，label2，input，当 type 为 default 类型时，传值 type=“”即可，页面效果如下：
当 type 为 check 类型时，页面效果如下：
当 type 为 label 类型时，页面效果如下：
当 type 为 label2 类型时，页面效果如下：
当 type 为 input 类型时，页面效果如下：
- 参数配置见下图，可根据实际需求进行调整：
