vue-cli3和element做一個簡單的登陸頁面-有解無憂

1.先用vue-cli3創建一個專案

2.安裝element模塊

全域安裝

 npm i element-ui -S

3在main.js引入模塊

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

Vue.use(ElementUI);

4.這里先擴展一個小知識點

在package.json檔案中找scripts下serve,在后面加上--open 可以實作運行專案后自動打開瀏覽器

5.然后我們在views檔案夾下新建一個登陸頁面login.vue

6.搭建login頁面(這里我們簡單的用element修飾一下)

<template>
  <div class="firstdemo">
    <el-form ref="form" :model="form" label-width="80px">
      <el-row type="flex" justify="center">
        <el-col :span="5">
          <el-form-item label="用戶名">
            <el-input v-model="form.name"></el-input>
          </el-form-item>
        </el-col>
      </el-row>
      <el-row type="flex" justify="center">
        <el-col :span="5">
          <el-form-item label="密碼">
            <el-input v-model="form.password"></el-input>
          </el-form-item>
        </el-col>
      </el-row>

      <el-row type="flex" justify="center">
        <el-col :span="5">
          <el-form-item>
            <el-button type="primary" @click="onSubmit">登陸</el-button>
            <el-button>注冊</el-button>
          </el-form-item>
        </el-col>
      </el-row>
    </el-form>
  </div>
</template>
<script>
export default {
  name: "fisrtdemo",
  data() {
    return {
      form: {
        name: "",
        password: ""
      }
    };
  },
  methods: {
    onSubmit() {
      if (this.form.name == "admin" && this.form.password == "123456") {
       this.$message({
          message: '登陸成功',
          type: 'success'
        }); 
       this.$router.push({ path: "/Home" });
      }else{
         this.$message.error('登陸失敗');
      }
    }
  }
};
</script>
<style lang="stylus" scoped></style>

由于只是簡單的展示以下這里我們用一個死資料

這里簡單強調一下在邏輯層實作路由切換

　　　　　<!-- 宣告式導航 應用于視圖層 -->
        <router-link to='/foo'>to foo</router-link>
        <router-view></router-view>
        <!-- 編程式導航 應用于邏輯層-->
        <!-- router.push({path:'/foo'}) -->

到這里login頁面基本搭建完成

7.在router下的index.js中引入我們剛剛創建的login.vue

并對路徑作相應改動

index.js

import Vue from "vue";
import VueRouter from "vue-router";
import Home from "../views/Home.vue";
import login from "../views/login.vue";
Vue.use(VueRouter);

const routes = [
  {
    path: "/",
    name: "login",
    component: login
  },
  {
    path: "/Home",
    name: "home",
    component: Home
  },
  {
    path: "/about",
    name: "about",
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    component: () =>
      import(/* webpackChunkName: "about" */ "../views/About.vue")
  }
];

const router = new VueRouter({
  mode: "history",
  base: process.env.BASE_URL,
  routes
});

export default router;

8.最后我們對home作一下簡單修飾，

博主這里在components中新建了一個組件helloworld并引入了element中的一個簡單的布局容器，

然后在home頁面引入helloworld對頁面進行渲染(當然也可以像上面一樣直接在home中引入element布局容器)

9.運行 npm run serve

10.下面展示以下效果
