全栈课程笔记：Element UI分类列表、分类编辑

页面

1.创建分类

2.编辑分类

3.新增物品

4.编辑物品

安装必要模块

npm i axios -s

路由建立

import Vue from 'vue'
import Router from 'vue-router'
import Home from './views/Home.vue'
import Main from './views/Main.vue'
import CategoryEdit from './views/CategoryEdit.vue'
import CategoryList from './views/CategoryList.vue'

import ItemEdit from './views/ItemEdit.vue'
import ItemList from './views/ItemList.vue'

Vue.use(Router)

export default new Router({
  mode: 'history',
  base: process.env.BASE_URL,
  routes: [
    {
      path: '/',
      name: 'Main',
      component: Main,
      children: [
        { path: '/categories/create', component: CategoryEdit },
        { path: '/categories/edit/:id', component: CategoryEdit, props: true },
        { path: '/categories/list', component: CategoryList },

        { path: '/items/create', component: ItemEdit },
        { path: '/items/edit/:id', component: ItemEdit, props: true },
        { path: '/items/list', component: ItemList }
      ]
    }
  ]
})

Axios

建立http.js文件

import axios from 'axios'

const http = axios.create({
    baseURL: 'http://localhost:3000/admin/api'
})

export default http

然后在main.js中加上

import http from './http'
Vue.prototype.$http = http
