How to implement data-driven display of jsmind-based mind maps in Vue?

Introduction:
Vue is a popular JavaScript framework focused on building user interfaces. jsMind is a lightweight JavaScript mind mapping library, used to visually display complex thinking structures. This article will introduce how to use jsMind in Vue to implement the function of data-driven display of mind maps.

Step 1: Install dependencies
First install jsMind in the Vue project. You can use npm or yarn to install.

npm install jsmind

or

yarn add jsmind

Step 2: Create jsMind component
Create a new component in the Vue project to display the mind map. Suppose we name the component MindMap.

<template>
  <div ref="mindMapContainer" class="mind-map-container"></div>
</template>

<script>
import jsMind from 'jsmind'

export default {
  name: 'MindMap',
  props: ['data'],
  mounted() {
    const mind = new jsMind(this.$refs.mindMapContainer)
    mind.show(this.data)
  }
}
</script>

<style scoped>
.mind-map-container {
  width: 600px;
  height: 400px;
}
</style>

In the above code, we first imported the jsMind library, instantiated a jsMind object in the mounted hook function and passed in the reference to the container, and then called the show method of the object to display the mind guidance picture.

Step 3: Use the MindMap component in the parent component
Use the MindMap component in the parent component and pass in the mind map data that needs to be displayed.

<template>
  <div>
    <MindMap :data="mindMapData" />
  </div>
</template>

<script>
import MindMap from './MindMap.vue'

export default {
  components: {
    MindMap
  },
  data() {
    return {
      mindMapData: {
        meta: {
          name: '思维导图',
          author: 'You',
          version: '1.0'
        },
        format: 'node_array',
        data: [
          { id: 'root', isroot: true, topic: '根节点' },
          { id: 'node1', parentid: 'root', topic: '节点1' },
          { id: 'node2', parentid: 'root', topic: '节点2' },
          { id: 'node3', parentid: 'root', topic: '节点3' },
          { id: 'node4', parentid: 'node1', topic: '节点1.1' },
          { id: 'node5', parentid: 'node1', topic: '节点1.2' }
        ]
      }
    }
  }
}
</script>

In the above code, we first imported the MindMap component and defined the mind map data in the data attribute. The data structure can be modified according to the actual situation. Then pass the data to the MindMap component through props.

Through the above steps, we have successfully implemented the data-driven display function of mind maps in Vue using jsMind.

Conclusion:
In this article, we introduced how to use jsMind in Vue to implement a data-driven mind map display function. By creating a jsMind component and passing data to the component through props, we can easily display complex mind structures in Vue projects. At the same time, we can customize styles, interactions and other functions according to actual needs to achieve a richer mind map display effect.
