如何使用

安装

NPM

npm i mind-elixir -S

import MindElixir, { E } from 'mind-elixir'

Script 标签

<script src="https://cdn.jsdelivr.net/npm/mind-elixir/dist/mind-elixir.js"></script>

HTML 结构

<div id="map"></div>
<style>
  #map {
    height: 500px;
    width: 100%;
  }
</style>

初始化

import MindElixir, { E } from 'mind-elixir'
import { exportSvg, exportPng } from '../dist/painter'
import example from '../dist/example1'

let options = {
  el: '#map',
  direction: MindElixir.LEFT,
  // create new map data
  data: MindElixir.new('new topic') or example,
  // the data return from `.getAllData()`
  draggable: true, // default true
  contextMenu: true, // default true
  toolBar: true, // default true
  nodeMenu: true, // default true
  keypress: true, // default true
  locale: 'en', // [zh_CN,zh_TW,en,ja,pt] waiting for PRs
  overflowHidden: false, // default false
  primaryLinkStyle: 2, // [1,2] default 1
  primaryNodeVerticalGap: 15, // default 25
  primaryNodeHorizontalGap: 15, // default 65
  contextMenuOption: {
    focus: true,
    link: true,
    extend: [
      {
        name: 'Node edit',
        onclick: () => {
          alert('extend menu')
        },
      },
    ],
  },
  allowUndo: false,
  before: {
    insertSibling(el, obj) {
      return true
    },
    async addChild(el, obj) {
      await sleep()
      return true
    },
  },
}

let mind = new MindElixir(options)
mind.init()

// get a node
E('node-id')

数据结构

// whole node data structure up to now
{
  topic: 'node topic',
  id: 'bd1c24420cd2c2f5',
  style: { fontSize: '32', color: '#3298db', background: '#ecf0f1' },
  parent: null,
  tags: ['Tag'],
  icons: ['😀'],
  hyperLink: 'https://github.com/ssshooter/mind-elixir-core',
}

事件处理

mind.bus.addListener('operation', operation => {
  console.log(operation)
  // return {
  //   name: action name,
  //   obj: target object
  // }

  // name: [insertSibling|addChild|removeNode|beginEdit|finishEdit]
  // obj: target

  // name: moveNode
  // obj: {from:target1,to:target2}
})

mind.bus.addListener('selectNode', node => {
  console.log(node)
})

mind.bus.addListener('expandNode', node => {
  console.log('expandNode: ', node)
})

数据导出

mind.getAllData() // javascript object, see src/example.js
mind.getAllDataString() // stringify object
mind.getAllDataMd() // markdown

输出图片

WIP

import painter from 'mind-elixir/dist/painter'
painter.exportSvg()
painter.exportPng()

操作拦截

let mind = new MindElixir({
  ...
  before: {
    insertSibling(el, obj) {
      console.log(el, obj)
      if (this.currentNode.nodeObj.parent.root) {
        return false
      }
      return true
    },
    async addChild(el, obj) {
      await sleep()
      if (this.currentNode.nodeObj.parent.root) {
        return false
      }
      return true
    },
  },
})
