Vue配置路由

Vue配置路由

1. 工程目录

-sec
	-assets	
	-components	#功能组件
	-router
		index.js
	-views #试图组件
		Login.vue
		Main.vue
	App.vue
	main.js

2.编写Views中的试图组件

• Main.vue

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

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

<style scoped>

</style>

• Login.vue 【element ui】

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

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

        // 表单验证，需要在 el-form-item 元素中增加 prop 属性
        rules: {
          username: [
            {required: true, message: '账号不可为空', trigger: 'blur'}
          ],
          password: [
            {required: true, message: '密码不可为空', trigger: 'blur'}
          ]
        },

        // 对话框显示和隐藏
        dialogVisible: false
      }
    },
    methods: {
      onSubmit(formName) {
        // 为表单绑定验证功能
        this.$refs[formName].validate((valid) => {
          if (valid) {
            // 使用 vue-router 路由到指定页面，该方式称之为编程式导航
            this.$router.push("/main");
          } 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>

3. router目录下创建index.js配置路由

// 引入vue和vue-router
import Vue from 'vue';
import Router from 'vue-router';

// 申明使用Router
Vue.use(Router);

// 引入刚刚写的两个试图组件
import Main from "../views/Main";
import Login from "../views/Login";

// 暴露 这里的`Router`要与上面import中的`Router`对应
export default new Router({
  routes: [
    {
      path: '/main',	// 地址
      name: 'main', 	// 名称
      component: Main	// 组件
    },
    {
      path: '/login',
      name: 'login',
      component: Login
    }
  ]
})

4. 在main.js中配置路由器

// 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'

// 引入路由
import router from './router'  

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

Vue.use(ElementUI);

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  el: '#app',
  router,	// 添加router属性。
  components: { App },
  template: '<App/>',
  render: h => h(App) // Element UI
})
