How to use Vue and jsmind to implement the annotation and batch editing functions of mind maps?

Mind map is a graphic tool used to organize and express thinking. It can help us organize and sort out our ideas and improve the integrity and logic of our thinking. In daily work and study, we often need to annotate and batch edit mind maps to further improve and expand our thinking.

As a popular JavaScript framework, Vue provides a convenient and efficient component-based development method. Combined with jsmind, an excellent mind map library, it can well realize the annotation and batch editing functions of mind maps. .

Below I will use a specific example to introduce in detail how to use Vue and jsmind to implement the annotation and batch editing functions of mind maps.

First, we need to install and introduce the relevant libraries and components of Vue and jsmind. It can be introduced through npm or directly through scripting.

<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script src="https://unpkg.com/jsmind/dist/jsmind.js"></script>
<link rel="stylesheet" href="https://unpkg.com/jsmind/dist/jsmind.snow.css">

Next, we create a Vue component to host the mind map and implement annotation and batch editing functions.

<template>
  <div>
    <div ref="jsmind_container"></div>
    <button @click="addNote">添加批注</button>
    <button @click="batchEdit">批量编辑</button>
  </div>
</template>

<script>
export default {
  mounted() {
    this.initMindMap();
  },
  methods: {
    initMindMap() {
      const mind = {
        meta: {},
        format: 'node_array',
        data: [
          { 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: this.$refs.jsmind_container,
        editable: true
      };

      this.jsmind_instance = jsMind.show(options, mind);
    },
    addNote() {
      const selectedNode = this.jsmind_instance.get_selected_node();
      if (selectedNode) {
        const note = prompt('请输入批注：');
        selectedNode.note = note;
        this.jsmind_instance.update_node(selectedNode.id, selectedNode);
      }
    },
    batchEdit() {
      this.jsmind_instance.edit_with_editor({ multiple: true });
    }
  }
};
</script>

In the above code, we first call the initMindMap method in the mounted hook function to initialize the mind map. In the initMindMap method, we create a mind object to store the mind map data, including the node id, parent node id, and topic. Then, the mind map is displayed by calling the show method of the jsMind library.

In the addNote method, we obtain the currently selected node and let the user enter the comment content through the prompt method. Then, assign the annotation content to the note attribute of the selected node, and call the update_node method of the jsMind library to update the node.

In the batchEdit method, we call the edit_with_editor method of the jsMind library and pass in the multiple parameter as true to enable batch editing mode.

Finally, in the template, we trigger the addNote and batchEdit methods by clicking the button, thereby realizing the annotation and batch editing functions of the mind map.

Using Vue and jsmind to implement mind map annotation and batch editing functions can make us think and organize more conveniently. I hope the above examples can help you and improve your work and learning efficiency.
