本文实例为大家分享了vue递归组件实现elementUI多级菜单的具体代码，供大家参考，具体内容如下
先看效果：
一、子组件
{{item.title}}
{{item.title}}
二、菜单数据准备
菜单中包含索引，图片，名称，跳转路径，这里我给出一部分数据，路由直接用数字了，你们最好定义为组件的英文名称，这样方便维护。
export function menuJson() {
var data = [{
title: "元数据管理",
img: "../../../static/img/manager.png",
index: '1',
child: [
{
"title": "元数据信息描述管理", "path": "main/02/005", "img": "../../../static/img/manager.png", "index": "1-2", "child": []
},
{
"title": "元数据分组定义管理", "path": "main/02/007", "img": "../../../static/img/manager.png", "index": "1-3", "child": []
},
{
"title": "元数据信息管理", "path": "main/02", "img": "../../../static/img/manager.png", "index": "1-1", "child": [
{ "title": "采集元数据", "path": "main/02/001", "index": "1-1-1", "img": "../../../static/img/blood.png", "child": [] },
{ "title": "元模型", "path": "main/02/004", "index": "1-2-1", "img": "../../../static/img/blood.png", "child": [] },
]
},
{
"title": "元数据统计分析管理", "path": "main/01", "index": "1-4", "img": "../../../static/img/manager.png", "child": [
{ "title": "元数据变更管理", "path": "main/01/001", "index": "1-4-1", "img": "../../../static/img/blood.png", "child": [] },
{ "title": "数据地图", "path": "main/01/002", "index": "1-4-2", "img": "../../../static/img/blood.png", "child": [] },
{
"title": "元数据分析", "path": "main/01/003", "index": "1-4-3", "img": "../../../static/img/yuanfenxi.png", "child": [
{ "title": "血缘分析", "path": "main/01/003/0001", "index": "1-4-3-1", "img": "../../../static/img/blood.png", "child": [] },
{ "title": "属性差异分析", "path": "main/01/003/0003", "index": "1-4-3-2", "img": "../../../static/img/chayi.png", "child": [] },
{ "title": "影响分析", "path": "main/01/003/0004", "index": "1-4-3-3", "img": "../../../static/img/impact.png", "child": [] },
]
},
]
},
]
},
{
title: "规则管理",
img: "../../../static/img/manager.png",
index: '2',
child: [
{ "title": "数据接口定义管理", "index": "2-1", "path": "main/03/001", "img": "../../../static/img/source.png", "child": [] },
{ "title": "数据转换规则管理", "index": "2-2", "path": "main/03/004", "img": "../../../static/img/modify.png", "child": [] },
]
}
]
return data
}
三、父组件调用
补充（面包屑的展示）：
有菜单，肯定需要面包屑的展示，例如
这里我用的方法是，根据当前页面名称，从树形菜单数据中查找它的所有父级来实现面包屑导航栏的展示。
html：
{{item}}
methods:
methods: {
//获取树形数据的某个元素的所有父节点
getTreePath(tree, func, path) {
if (!tree) return []
for (const data of tree) {
// 这里按照你的需求来存放最后返回的内容吧
//这里的title是我的菜单数据里面的名称字段，你可以改成你的
path.push(data.title)
if (func(data)) return path
if (data.child) {
//获取到子数据，递归调用
const findChildren = this.getTreePath(data.child, func, path)
if (findChildren.length) return findChildren
}
path.pop()
}
return []
},
// 获取面包屑
getNavList() {
var name = this.$route.query.r_n //先获取当前路由名称
var tree = menuJson() //获取菜单数据，menuJson这个函数上面用了，返回的事菜单数据
this.path = [] //path用于存放所有父级，调用前需要清空
//data => data.title === name查找数据中的title是否和当前路由名称相等
this.getTreePath(tree, data => data.title === name, this.path)
this.listMenu = this.path //找到之后赋值给面包屑路由数组
console.log(this.listMenu)
}
}
