本篇内容主要讲解“Vue实现菜单功能的代码怎么写”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“Vue实现菜单功能的代码怎么写”吧!
菜单管理是一个对菜单树结构的增删改查操作。
提供一个菜单查询接口，查询整颗菜单树形结构。
http/modules/menu.js 添加findMenuTree 接口。
import axios from '../axios'
/*
* 菜单管理模块
*/
// 保存
export const save = (data) => {
return axios({
url: '/menu/save',
method: 'post',
data
})
}
// 删除
export const batchDelete = (data) => {
url: '/menu/delete',
// 查找导航菜单树
export const findNavTree = (params) => {
url: '/menu/findNavTree',
method: 'get',
params
export const findMenuTree = () => {
url: '/menu/findMenuTree',
method: 'get'菜单管理界面是使用封装的表格树组件显示菜单结构，并提供增删改查的功能。
