How to use Vue and jsmind to create a dynamic editable mind map?

Introduction: Mind mapping is an effective tool for organizing and presenting thinking processes. In web applications, we can use Vue and jsmind to create dynamic editable mind maps. This article will show you how to use Vue and the jsmind library to achieve this functionality.

1. Introduction to jsmind
jsmind is a lightweight, elegant, customizable mind mapping library. It is developed based on JavaScript and can be easily integrated into Vue applications. It supports creating and editing mind maps, as well as exporting and importing map data.

2. Start the project
First, create a Vue project. You can use the Vue CLI to initialize a new project. Execute the following command:

vue create mindmap-app

Follow the prompts to select your own project configuration, then enter the project directory and start the development server:

cd mindmap-app
npm run serve

3. Install jsmind
In the project directory, use the following command To install the jsmind library:

npm install jsMind

4. Write the Vue component
Create a component named MindMap.vue and introduce the jsmind library into it. Next, we will write Vue templates, styles and scripts to implement dynamic editable mind maps.

<template>
  <div>
    <div ref="jsmindContainer" class="jsmind-container"></div>
    <button @click="exportData">导出导图数据</button>
    <button @click="importData">导入导图数据</button>
  </div>
</template>

<script>
import $ from 'jquery';
import jsMind from 'jsmind';

export default {
  mounted() {
    this.initMindMap();
  },
  methods: {
    initMindMap() {
      const mindMapContainer = this.$refs.jsmindContainer;
      const mind = {
        /* 定义导图数据 */
        nodes: [
          { id: 'root', isroot: true, topic: '思维导图' },
          { id: 'node1', parentid: 'root', topic: '节点1' },
          { id: 'node2', parentid: 'root', topic: '节点2' },
          { id: 'node3', parentid: 'root', topic: '节点3' },
        ],
      };

      const options = {
        container: mindMapContainer,
        editable: true,
        theme: 'primary',
      };

      const jm = new jsMind(options);
      jm.show(mind);

      this.jm = jm;
    },
    exportData() {
      const mindData = this.jm.mind.export_data();
      console.log('导出导图数据：', mindData);
    },
    importData() {
      /* 导入导图数据的逻辑 */
    },
  },
};
</script>

<style scoped>
.jsmind-container {
  width: 100%;
  height: 500px;
}
</style>

In the above code, we first introduced the jQuery library, because jsmind depends on jQuery. Then, we call the initMindMap method in the mounted hook function to initialize the mind map. By creating a jsMind instance and displaying it in a specified container, we can create and display mind maps. Next, we define two buttons for exporting and importing map data. Through the export_data method, we can obtain the mind map data and then print it out in the console. You can implement the processing logic for imported data according to your needs.

5. Complete the mind map application
Now, you can run your Vue application and access it in the browser. You'll see a dynamically editable mind map, and can export and import map data.

npm run serve

6. Summary
By using Vue and jsmind libraries, we can easily create dynamic and editable mind maps. In this article, we learned how to initialize a mind map, and how to export and import map data. I hope this article was helpful and enabled you to implement similar functionality in your own projects.
