Vue+Element-ui建立一個登陸頁面

Vue+Element-ui建立一個登陸頁面

效果圖

1.建立一個Vue專案
2.安裝element-ui元件
3.安裝sass-loader元件
4.編寫程式碼
5.執行專案

在當前目錄下安裝elemrnt-ui

PS D:\HBuilder\filer\MeetingManage> npm install element-ui -S

隨後安裝sass-loader

PS D:\HBuilder\filer\MeetingManage> npm install sass-loader node-sass --save-dev

開始編寫程式碼
在components資料夾下建立一個content.vue檔案

<template>
<div>
  <el-form ref="loginForm" :model="form" :rules="rules" label-width="80px" class="login-box">
    <h3 class="login-title">歡迎登入</h3>
    <el-form-item label="賬號" prop="username">
      <el-input type="text" placeholder="請輸入賬號" v-model="form.username"/>
    </el-form-item>
    <el-form-item label="密碼" prop="password">
      <el-input type="password" placeholder="請輸入密碼" v-model="form.password"/>
    </el-form-item>
    <el-form-item>
      <el-button type="primary" v-on:click="onSubmit('loginForm')">登入</el-button>
    </el-form-item>
  </el-form>

  <el-dialog
    title="溫馨提示"
    :visible.sync="dialogVisible"
    width="30%"
    >
    <span>請輸入賬號和密碼</span>
    <span slot="footer" class="dialog-footer">
        <el-button type="primary" @click="dialogVisible = false">確 定</el-button>
      </span>
  </el-dialog>
</div>
</template>

<script>
  export default {
    name: "Content",
    data() {
      return {
        form: {
          username: '',
          password: ''
        },

        // 表單驗證，需要在 el-form-item 元素中增加 prop 屬性
        rules: {
          username: [
            {required: true, message: '賬號不可為空', trigger: 'blur'}
          ],
          password: [
            {required: true, message: '密碼不可為空', trigger: 'blur'}
          ]
        },

        // 對話方塊顯示和隱藏
        dialogVisible: false
      }
    },
    methods: {
      onSubmit(formName) {
        // 為表單繫結驗證功能
        this.$refs[formName].validate((valid) => {
          if (valid) {
            // 使用 vue-router 路由到指定頁面，該方式稱之為程式設計式導航
            this.$router.push("/main/"+this.form.username);
          } else {
            this.dialogVisible = true;
            return false;
          }
        });
      }
    }
  }
</script>

<style lang="scss" scoped>
  .login-box {
    border: 1px solid #DCDFE6;
    width: 350px;
    margin: 180px auto;
    padding: 35px 35px 15px 35px;
    border-radius: 5px;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    box-shadow: 0 0 25px #909399;
  }

  .login-title {
    text-align: center;
    margin: 0 auto 40px auto;
    color: #303133;
  }
</style>

在src下建立一個router檔案，檔案下建立index.js

import Vue from "vue";
import VueRouter from "vue-router";
import Content from "../components/Content.vue"

Vue.use(VueRouter);
export default new VueRouter({

  routes:[
    {
      path:'/Content',
      name:'Content',
      component:Content
    }
  ]
});

修改App.vue檔案

<template>
  <div id="app">
    <h1></h1>
    <router-link to="/Content">登入</router-link>

    <router-view ></router-view>
  </div>
</template>

<script>
import Content from './components/Content'
export default {
  name: 'App'
}
</script>

最後編輯main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from "./router"//自動是掃描裡面的配置
import ElementUI from "element-ui";

import 'element-ui/lib/theme-chalk/index.css'
Vue.config.productionTip = false

Vue.use(router);
Vue.use(ElementUI);
/* eslint-disable no-new */

new Vue({
  el: '#app',
  router,
  render: h=>h(App)
})

最後執行介面就可以了，效果圖
