What are the steps to use Vue and jsmind to implement multiple mind map theme styles?

Mind map is a tool commonly used to organize thinking and clarify ideas. Vue.js is a popular JavaScript framework for building user interfaces. jsmind is a mind mapping library based on HTML5 technology, which provides a rich theme style to meet the needs of different users. This article will introduce how to use Vue and jsmind to implement multiple mind map theme styles.

The steps are as follows:

Step 1: Build a basic environment
First, you need to build a Vue.js development environment. You can use the Vue CLI to quickly create a Vue project. Enter the following command in the terminal:

vue create jsmind-demo
cd jsmind-demo

Then, install jsmind. Enter the following command in the terminal:

npm install jsmind

Step 2: Create a mind map component
Create a components directory in the src directory, and then create a MindMap.vue file in the directory. In this file, introduce the jsmind library and css files, and create a MindMap component.

<template>
  <div ref="mindmap"></div>
</template>

<script>
import 'jsmind';
import 'jsmind/style/jsmind.css';

export default {
  name: 'MindMap',
  props: ['mindData'],
  mounted() {
    const mind = {
      meta: {},
      format: 'node_array',
      data: this.mindData
    };
    const options = {
      container: this.$refs.mindmap,
      theme: 'orange'
    };
    const jm = new jsMind(options);
    jm.show(mind);
  }
};
</script>

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

In the above code, we define a MindMap component. Use refs to obtain DOM elements, then initialize jsmind in the mounted hook function, and render the incoming mind map data through props.

Step 3: Use multiple theme styles
jsmind provides a variety of built-in theme styles, which can be switched by setting the theme attribute in options. Here are examples of several theme styles:

• Theme Style 1 (blue):

const options = {
  container: this.$refs.mindmap,
  theme: 'blue'
};

• Theme Style 2 (black):

const options = {
  container: this.$refs.mindmap,
  theme: 'dark'
};

• Theme style 3 (green):

const options = {
  container: this.$refs.mindmap,
  theme: 'green'
};

• Theme style 4 (orange):

const options = {
  container: this.$refs.mindmap,
  theme: 'orange'
};

Replace the above code You can use different theme styles by changing the options configuration in the MindMap.vue file.

Step 4: Use the component
Use the MindMap component in the App.vue file and pass in the mind map data and the selected theme style.

<template>
  <div id="app">
    <MindMap :mindData="mindData" />
    <div>
      <button @click="changeTheme('blue')">蓝色</button>
      <button @click="changeTheme('dark')">黑色</button>
      <button @click="changeTheme('green')">绿色</button>
      <button @click="changeTheme('orange')">橙色</button>
    </div>
  </div>
</template>

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

export default {
  name: 'App',
  components: {
    MindMap
  },
  data() {
    return {
      mindData: [
        {
          id: 'root',
          topic: '思维导图',
          children: [
            {
              id: 'child1',
              topic: '主题样式1'
            },
            {
              id: 'child2',
              topic: '主题样式2'
            }
          ]
        }
      ],
      theme: 'orange'
    };
  },
  methods: {
    changeTheme(theme) {
      this.theme = theme;
    }
  },
  watch: {
    theme(newTheme) {
      const options = {
        container: this.$refs.mindmap,
        theme: newTheme
      };
      const jm = new jsMind(options);
      jm.show({ data: this.mindData });
    }
  }
};
</script>

In the above code, we use four buttons to switch theme styles, and use watch to listen for changes in the theme attributes to dynamically update the theme style of the mind map.

So far, we have completed the steps of using Vue and jsmind to implement multiple mind map theme styles. You can choose a suitable theme style to beautify your mind map according to your needs. Hope this article is helpful to you!
