What are the methods to implement interactive mind mapping using Vue and jsmind?

Mind mapping is a tool that presents thinking and relationships in a graphical way. It is widely used in knowledge organization, problem solving and project management. Vue is a popular JavaScript framework, and jsmind is a mind mapping library based on HTML5. Combining Vue and jsmind, we can implement an interactive mind map to facilitate users to create, edit and browse mind maps.

Before using Vue and jsmind to implement interactive mind maps, we need to prepare the relevant environment and resources. First, we need to introduce the Vue and jsmind library files into the project. It can be installed through npm or introduced using CDN. Next, we need to create a Vue instance and set up the jsmind container in it.

<template>
  <div>
    <div id="jsmind_container"></div>
  </div>
</template>

<script>
import jsMind from 'jsmind'
import 'jsmind/style/jsmind.css'

export default {
  mounted() {
    const mind = {
      meta: {
        name: '思维导图',
        author: '作者'
      },
      format: 'node_array',
      data: [
        { id: 'root', isroot: true, topic: '主题', direction: 'right', expanded: true }
      ]
    }
    const jm = new jsMind({
      container: 'jsmind_container',
      editable: true,
      theme: 'primary'
    })
    jm.show(mind)
  }
}
</script>

<style>
#jsmind_container {
  width: 100%;
  height: 500px;
}
</style>

In the above code, we first introduced the library files of Vue and jsmind, and set the style of the jsmind container. Then, in Vue's mounted hook, we created an instance of jsMind and specified related configurations such as the container, whether it is editable, and the theme. Next, we create an initial mind map data object as needed, which contains the basic information and root node of the map. Finally, call the jm.show(mind) method to display the map in the specified container.

In addition to displaying the mind map, we can also add some interactive functions to the Vue component, such as adding nodes, deleting nodes, modifying nodes, etc. The following is an example of implementing an interactive mind map in a Vue component:

<template>
  <div>
    <div id="jsmind_container"></div>
    <button @click="addNode">添加节点</button>
    <button @click="deleteNode">删除节点</button>
    <button @click="editNode">修改节点</button>
  </div>
</template>

<script>
import jsMind from 'jsmind'
import 'jsmind/style/jsmind.css'

export default {
  mounted() {
    // 初始化思维导图
  },
  methods: {
    addNode() {
      const node = {
        id: 'node_id',
        parentid: 'root',
        topic: '子节点'
      }
      jm.add_node(node.id, node.parentid, node.topic)
    },
    deleteNode() {
      const nodeid = 'node_id'
      jm.remove_node(nodeid)
    },
    editNode() {
      const nodeid = 'node_id'
      const topic = '修改后的节点'
      jm.update_node(nodeid, topic)
    }
  }
}
</script>

<style>
#jsmind_container {
  width: 100%;
  height: 500px;
}
</style>

In the above code, we implement the functions of adding nodes, deleting nodes, and modifying nodes through Vue's binding events. . By calling the relevant methods provided by jsmind, we can dynamically operate the nodes of the mind map.

To sum up, using Vue and jsmind to implement interactive mind maps can create an instance of jsmind and use related methods to add, delete, modify and check nodes. Through Vue's event binding, we can dynamically modify the content and structure of the mind map. In this way, we can implement a flexible and interactive mind mapping application.
