前后端分离之建立vue项目(二)

昨天基于vue搭建了一个简单的项目骨架,但是问题来了,难道我们要自己写页面写样式吗?就没有向Bootstrap或者layui那样的框架吗?别急,有的,element-ui

安装element-ui

接着昨天的项目进行开发,终端或者cmd进入项目根目录

npm i element-ui -d

i就是install的简写

引入element-ui

在main.js引入

import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';

import routes from './js/router/routes.js'

Vue.use(VueRouter);
Vue.use(ElementUI);
const router = new VueRouter({
	//去掉链接中#号
	mode:'history',
	routes:routes
})

new Vue({
	router,
	el: '#app',
	render: h => h(App)
})
开启字体文件访问,打开webpack.config.js

修改
 {
	 test: /\.(png|jpg|gif|svg)$/,
	 loader: 'file-loader',
	 options: {
	 name: '[name].[ext]?[hash]'
	 }
 }
 为
 {
	 test: /\.(ttf|woff|png|jpg|gif|svg)$/,
	 loader: 'file-loader',
	 options: {
	 name: '[name].[ext]?[hash]'
	 }
 }

搞定

测试

修改我们的foo.vue

<template>
	<div id="foo">
		<el-row>
			<el-button>默认按钮</el-button>
			<el-button type="primary">主要按钮</el-button>
			<el-button type="success">成功按钮</el-button>
			<el-button type="info">信息按钮</el-button>
			<el-button type="warning">警告按钮</el-button>
			<el-button type="danger">危险按钮</el-button>
		</el-row>
	</div>
</template>

<script>
	export default {
		name:"foo",
		data() {
			return {
				
			};
		}
	}
</script>

<style>

</style>

删掉app.vue多余文字

<template>
  <div id="app">
		<router-view></router-view>
  </div>
</template>

<script>
export default {
  name: 'app',
  data () {
    return {
      
    }
  }
}
</script>

<style>

</style>

运行项目

npm run dev

重启项目并访问http://localhost:8080/ 可以看到如下界面

ok.感觉方便了很多…
另外如果要修改端口号,可以在webpack.config.js作如下修改:

找到:
devServer: {
    historyApiFallback: true,
    noInfo: true,
    overlay: true
}
增加端口信息
devServer: {
	port:8081,
    historyApiFallback: true,
    noInfo: true,
    overlay: true
}

这样,再启动项目就是8081端口了,接下来我们写一个简单的登录页面

创建Login.vue

在components文件夹下新建Login.vue,作为演示页面,也不用写的太好,能看就行~

<template>
	<div id="login">
		<el-form ref="user" :model="user" label-width="80px" class="login-form" :label-position="labelPosition" :rules="rules">
			<el-form-item label="用户名" prop="name">
				<el-input v-model="user.name"></el-input>
			</el-form-item>
			<el-form-item label="密码" prop="pass">
				<el-input v-model="user.pass"></el-input>
			</el-form-item>
			<el-button type="primary" @click="onSubmit('user')" class="submit-btn">登录</el-button>
		</el-form>
	</div>
</template>

<script>
	export default {
		name:"login",
		data() {
			return {
				labelPosition: 'top',
				user:{
					name:"",
					pass:""
				},
				rules: {
					name: [
						{ required: true, message: '请输入用户名', trigger: 'blur' },
						{ min: 3, max: 10, message: '长度在 3 到 10 个字符', trigger: 'blur' }
					],
					pass: [
						{ required: true, message: '请输入密码', trigger: 'blur' }
					]
				}
			};
		},
		methods:{
			onSubmit(formName) {
				this.$refs[formName].validate((valid) => {
					if (valid) {
						alert('submit!');
					}
				});
			}
		}
	}
</script>

<style>
.login-form{
	width: 400px;
}
.submit-btn{
	width: 100%;
}
</style>

添加路由

修改routes.js:

import Foo from '../../components/Foo.vue'
import Bar from '../../components/Bar.vue'
import Login from '../../components/Login.vue'

export default[
	{path: '/', component:Login},
	{path: '/foo', component:Foo},
	{path: '/bar', component:Bar}
]

将login配置路径为/,这会使默认访问的页面就是login界面
