Vue实战快速上手

前言

ElementUI组件+vue

创建工程

1.创建一个名为 hello-vue 的工程

vue init webpack hello-vue

2.安装依赖.需要安装四个插件 vue-router,element-ui,sass-loader和node-sass

进入工程目录
  cd hello-vue
  安装vue-router
  npm install vue-router --save-dev
  安装element-ui
  npm i element-ui -s
  安装SASS加载器
  cnpm install sass-loader node-sass --save-dev
  启动测试
  npm run dev

创建登录页面

把没有用的初始化东西删掉
  结构如下

• assets: 用于存放资源文件
• components: 用于存放Vue功能组件
• views: 用于存放Vue视图组件
• router: 用于存放 vue-roter 配置

创建首页视图,在views目录下创建一个Main.vue的视图

<template>
      <h1>首页</h1>
  </template>

  <script>
      export default {
          name: "Main"
      }
  </script>

  <style scoped>

  </style>

创建登录页视图在views目录下创建一个名为Login.vue的视图

<template>
<div>
  <el-form :model="form"  :rules="rules" ref="loginForm" label-width="80px" class="login-box">
    <h3 class="login-title">欢迎登陆</h3>
    <el-form-item label="账号" prop="username">
      <el-input type="text" v-model="form.username" autocomplete="off" placeholder="请输入账号"></el-input>
    </el-form-item>
    <el-form-item label="密码" prop="password">
      <el-input type="password" v-model="form.password" autocomplete="off" placeholder="请输入密码"></el-input>
    </el-form-item>
    <el-form-item>
      <el-button type="primary" v-on:@click="onSubmit(‘loginForm‘)">登陆</el-button>
    </el-form-item>
  </el-form>

  <el-dialog
    title="温馨提示"
    :visible.sync="dialogVisible"
    width="30%"
    :before-close="handleClose">
    <span>请输入账号和密码</span>
    <span slot="footer" class="dialog-footer">
      <el-button type="primary" @click="dialogVisible=false">确定</el-button>
    </span>
  </el-dialog>
</div>

创建路由,在router目录下创建一个名为 index.js的vue-router的路由配置文件

import  Vue from ‘vue‘
import  Router from  ‘vue-router‘

import Main from ‘../view/Main‘
import Login from ‘../view/Login‘


import UserList from ‘../view/user/List‘
import UserProfile from ‘../view/user/Profile‘


Vue.use(Router);

export default  new Router({
  routes: [
    {
      path: ‘/login‘,
      component: Login,//嵌套路由
    },
    {
      path: ‘/main‘,
      component: Main,
      children:[
        {path: ‘/user/profile‘,component:UserProfile},
        {path: ‘/user/list‘,component:UserList},
      ]
    }
  ]
})

App.vue

<template>
  <div id="app">
    <router-link to="/login">login</router-link>
    <router-link to="/main">首页</router-link>
    <router-view></router-view>
  </div>
</template>

<script>
import HelloWorld from ‘./components/HelloWorld‘

export default {
  name: ‘App‘,
  components: {
    HelloWorld
  }
}
</script>

<style>
#app {
  font-family: ‘Avenir‘, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

mian.js

import Vue from ‘vue‘
  import App from ‘./App‘

  import router from ‘./router‘

  import ElementUI from ‘element-ui‘;
  import ‘element-ui/lib/theme-chalk/index.css‘;

  Vue.use(router);
  Vue.use(ElementUI);
  

  new Vue({
    el: ‘#app‘,
    router,
    render: h => h(App)//ElmentUI

  })
