没有特别多的数据

<template><el-tree:props="props":load="loadNode"lazyshow-checkbox></el-tree></template><script>export default {data() {return {props: {label: 'name',children: 'zones',isLeaf:"leaf",//关键},isLeaf:"",};},methods: {loadNode(node, resolve) {this.isLeaf = node.isLeaf;console.log(node,"nodeeeee");if (node.level === 0) {return resolve([{ name: 'region' }]);}if (node.level > 1) return resolve([]);setTimeout(() => {const data = [{name: 'leaf',leaf: true,//这个是控制箭头是否显示和不显示的，只要leaf为true那就证明没有子节点 //了，所以就不展示了icon箭头了}, {name: 'zone'}];resolve(data);}, 500);}}};</script>

希望对你有帮助
