创建vue工程
在vue工程目录下npm install vue
下载离线vue

安装服务端vue2语法提示
安装浏览器vue工具
谷歌商店下载
在打开html时候可以看到有个vue选项看到vue中的对象
Vue模块化开发
全局安装npm install webpack -g
全局安装npm install webpack -g @vue/cli-init
安装 sudo npm install -g @vue/cli
创建文件夹,使用vue init webpack vue-demo
选择默认的
进入demo工程启动,npm run dev
自己编写自己的vue的模块化页面
1.新增组件
<template>
<div>
<h1>你好,hello,{{ name }}</h1>
</div>
</template>
<script>
export default {
name: 'Hello',
data () {
return {
name: "张三"
}
}
}
</script>
<style scoped></style>
2.在index.js中引入新的组件并且添加新的路由配置
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Hello from '@/components/Hello'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'HelloWorld',
component: HelloWorld
},
{
path: '/hello',
name: 'Hello',
component: Hello
}
]
})
3.测试/hello
4.添加项目route本地跳转
在App.vue中添加 <router-link跳转
<template>
<div id="app">
<img src="./assets/logo.png">
<router-link to="/hello">去hello</router-link>
<router-link to="/">去首页</router-link>
<!-- 路由视图 -->
<router-view/>
</div>
</template>
<script>
export default {
name: 'App'
}
</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>
5.测试
安装element ui
npm i element-ui
在工程中也可以看到
1.在main.js中引入elementUI模块
// 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'
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,
components: { App },
template: '<App/>'
})
2.在Hello.vue组件中添加element 元素
<template>
<div>
<h1>你好,hello,{{ name }}</h1>
<el-radio v-model="radio" label="1" border>备选项1</el-radio>
<el-radio v-model="radio" label="2" border>备选项2</el-radio>
</div>
</template>
<script>
export default {
name: 'Hello',
data () {
return {
name: '张三',
radio: '2'
}
}
}
</script>
<style scoped>
3.测试结果,radio显示正常
4.添加Vue的快捷模版
粘贴保存
{
"Print to console": {
"prefix": "vue",
"body": [
"<!-- $1 -->",
"<template>",
"<div class='$2'>$5</div>",
"</template>",
"",

},
"http-get请求": {
"prefix": "httpget",
"body": [
"this.\\$http({",
"url: this.\\$http.adornUrl(''),",
"method: 'get',",
"params: this.\\$http.adornParams({})",

"})"
],

"method: 'post',",
"data: this.\\$http.adornData(data, false)",
"}).then(({ data }) => { });"
],
"description": "httpPOST请求"
}
}
5.创建组件
<!-- -->
<template>
<el-table :data="tableData">
<el-table-column prop="date" label="日期" width="140">
</el-table-column>
<el-table-column prop="name" label="姓名" width="120">
</el-table-column>
<el-table-column prop="address" label="地址">
</el-table-column>
</el-table>
</template>
<script>
//这里可以导入其他文件(比如:组件,工具js,第三方插件js,json文件,图片文件等等)
//例如:import 《组件名称》 from '《组件路径》';
export default {
//import引入的组件需要注入到对象中才能使用
components: {},
data() {
const item = {
date: '2016-05-02',
name: '王小虎',
address: '上海市普陀区金沙江路 1518 弄'
};
return {
tableData: Array(20).fill(item)
}
},
//监听属性 类似于data概念
computed: {},
//监控data中的数据变化
watch: {},
//方法集合
methods: {
},
//生命周期 - 创建完成(可以访问当前this实例)
created() {
},
//生命周期 - 挂载完成(可以访问DOM元素)
mounted() {
},
beforeCreate() { }, //生命周期 - 创建之前
beforeMount() { }, //生命周期 - 挂载之前
beforeUpdate() { }, //生命周期 - 更新之前
updated() { }, //生命周期 - 更新之后
beforeDestroy() { }, //生命周期 - 销毁之前
destroyed() { }, //生命周期 - 销毁完成
activated() { } //如果页面有keep-alive缓存功能,这个函数会触发
}
</script>
<style scoped></style>
6.添加路由/table
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Hello from '@/components/Hello'
import MyTable from '@/components/MyTable'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'HelloWorld',
component: HelloWorld
},
{
path: '/hello',
name: 'Hello',
component: Hello
},
{
path: '/table',
name: 'MyTable',
component: MyTable
}
]
})
7.修改App.vue
将el-main抽离到组件里文章来源:https://www.toymoban.com/news/detail-559459.html
<template>
<el-container style="height: 500px; border: 1px solid #eee">
