vue-jstree在这里https://github.com/zdy1988/vue-jstree

我是vue-cli建的项目

npm install vue-jstree --save

组件里这样写

import VJstree from 'vue-jstree';

import axios from "axios";

export default {

  name: 'Mytree',

  components: {

    VJstree

  },

  data() {

    return {

      data: []

            

    }

  },

  created() {

    axios.get('http://192.168.x.x/a2hs/treedata.php')

    .then(response => {

      this.data=response.data;      

    })

    .catch(e => {

      console.log(e)

    });

  },

动态返回的JSON数据格式如下

[{"id":1,"pid":0,"text":"node1","opened":0,"children":[{"id":43,"pid":1,"text":"node2","opened":0}...]}...]

如果有跨域问题，treedata.php输出前加

header('Access-Control-Allow-Origin: *');
