2）、使用组件

引入

import TreeChart from '@/components/TreeChart'

注册

components: { TreeChart },

使用

<TreeChart :json="data" :class="{landscape: 1}" />

数组

data: {
        name: '一级 1',
        image_url: "http://localhost:8888/20220407/a3214bd4-77c5-4c76-8ffc-06e7363e1419.jpg",
        class: ["rootNode"],
        children: [
          {
            name: '一级 1-1',
            image_url: "http://localhost:8888/20220407/a3214bd4-77c5-4c76-8ffc-06e7363e1419.jpg"
          },
          {
            name: '一级 1-2',
            image_url: "http://localhost:8888/20220407/a3214bd4-77c5-4c76-8ffc-06e7363e1419.jpg",
            children: [
              {
                name: '一级 1-1-2',
                image_url: "http://localhost:8888/20220407/a3214bd4-77c5-4c76-8ffc-06e7363e1419.jpg"
              },
              {
                name: '一级 1-1-2',
                image_url: "http://localhost:8888/20220407/a3214bd4-77c5-4c76-8ffc-06e7363e1419.jpg"
              },
              {

              }
            ]
          }
        ]
      }

样式

#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
#app .avat {
  border-radius: 2em;
  border-width: 2px;
}

#app .name {
  font-weight: 700;
}
