如何通过Vue和jsmind实现思维导图的节点复制和剪切功能？

// main.js
import Vue from 'vue'
import App from './App.vue'

Vue.config.productionTip = false

new Vue({
  render: h => h(App),
}).$mount('#app')

<template>
  <div>
    <div id="jsmind_container"></div>
    <button @click="copyNode">复制节点</button>
    <button @click="cutNode">剪切节点</button>
  </div>
</template>

<script>
import jsMind from 'jsmind'

export default {
  mounted() {
    this.initMind()
  },

  methods: {
    initMind() {
      const mind = {
        // 思维导图的数据
        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' }
        ]
      }

      this.mind = new jsMind({
        container: 'jsmind_container',
        editable: true
      })

      this.mind.show(mind)
    },
    
    copyNode() {
      const selectedNode = this.mind.get_selected_node()
      if (selectedNode) {
        const newNode = Object.assign({}, selectedNode.data) // 复制节点数据
        newNode.id = 'node' + (new Date().getTime()) // 生成新的节点id
        this.mind.add_node(selectedNode.parent, newNode) // 将新节点添加到选中节点的父节点下
      }
    },
    
    cutNode() {
      const selectedNode = this.mind.get_selected_node()
      if (selectedNode) {
        const parentNode = this.mind.get_node(selectedNode.parent)
        this.mind.remove_node(selectedNode) // 移除选中节点
        parentNode.expand = true // 展开父节点
        this.mind.select_node(parentNode.id) // 选中父节点
      }
    }
  }
}
</script>
