Vue仿抽屉

创建VUE项目的步骤：

npm install vue-cli -g

vue init webpack myproject

cd myproject

npm run dev 

 

 

组件：它是可扩展的html

里面包括：

<template></template>

<script></script>

<style></style>

VUE框架的特性：能够实现热重载

import 和require的区别：

import 一定要放在文件顶部

它相当于一个指针引用了文件，并没有把文件包含进来了，需要调用时才引入

require:

可以放在文件中任何位置

它是把文件直接包含进来

设置文件路由的流程：

1）建立组件(.vue文件)

2）配置路由(index.js 文件中的配置)

3）<router-link></router-link>

4)<router-view></router-view>

5)import 包名 from ‘’组件路径''

6）components 进行注册

vue-resource:实现异步数据加载(已经弃用)

axios:实现异步数据加载

 

Vue组件的生命周期：

1）定义Vue对象并实例化

2)created函数

3）编译muban

4）把HTML元素渲染到页面当中

5）mounted函数

6）如果有元素的更新，就执行updated函数

7)销毁实例

 代码如下：(有点小bug)
