vue 生命周期
1，beforeCreate 组件刚刚被创建
2，created 组件创建完成
3，beforeMount 挂载之前
4，mounted 挂载之后
5，beforeDestory 组件销毁前调用
6，destoryed 组件销毁后调用
<template>
<h3>我爱你</h3>
</template>
<script>
export default{
data(){
return{
}
},
beforeCreate(){
console.log("beforeCreate");
},
created(){
console.log('created');
},
beforeMount(){
console.log('beforeMount');
},
mounted(){
console.log('mounted');
},
beforeDestory(){
console.log('beforeDestory');
},
destoryed(){
console.log('destoryed');
}
}
</script>
在Vue.js的生命周期中，可以分为6个阶段，也就是6个函数代表6个阶段，不管顺序如何变，还是会按照以下顺序去执行代码：
beforeCreate（创建前）——>created（创建后）——>beforeMount(载入前)——>mounted（载入后）——>beforeDestroy（销毁前）——>destroyed（销毁后）
卸载命令：
卸载vue-cli : npm uninstall vue-cli -g
安装vue-cli : npm install --global vue-cli
卸载cnpm : npm uninstall cnpm -g
安装cnpm : npm install
---------以下是安装vue项目完整步骤，一：-----------
安装npm步骤：（其实直接可以使用Git软件里面的命令控制面板安装查看，和安装 vue 各种执行文件）
1，Win+R 打开命令面板---输入cmd，回车---在命令面板输入以下命令来查看相关软件的版本号:
a, node -v + 回车 直接百度安装node.js软件后再到命令控制面板查看版本号
v10.16.2
b, npm -v + 回车 安装完成node.js(npm是集成在node.js中的，如果nodejs安装成功，则npm也安装成功)，
如果有，则会出现版本号，否则就没有安装。
6.9.0
c, vue + 回车(这里是直接输入vue,没有-V) 安装成功后显示如下：（通过：npm install --global vue-cli 来安装的）
$ vue
Usage: vue <command> [options]
Options:
-V, --version output the version number <!-- 这里的V 一定是大写，才会出现版本号 -->
-h, --help output usage information
Commands:
init generate a new project from a template
list list available official templates
build prototype a new project
create (for v3 warning only)
help [cmd] display help for [cmd]
2，先安装node.js 下载安装指定盘符即可。
3，win+R 进入命令控制面板 输入：path + 回车，安装成功会在下方显示node.js，可以仔细查找以下。
path 为可执行文件显示或设置搜索路径(在命令控制面中输入：help，会出现一系列命令)
4，也可以直接输入 node -v 查看是否有安装成功，成功就会显示版本号。
5，安装:Git工具。
进入某个盘符，直接输入 D: + 回车即可。
但是如果要进入：D:\前端开发\HTML\组件化网页开发 步骤二 2-3 创建XMLHttpRequest对象\Ajax\register\img
这样的路径，使用手写方式就很麻烦了，所以需要一个工具来帮忙，
这个工具就是：官网：https://git-scm.com/ 点击 DownLoads --- 选择相应系统的版本下载安装即可。
安装完成，直接打开指定的文件夹，右击---选择---git bash here 进入到此处的子程序
马上就跳出一个在该路径下面的 node.js命令面板----就可以直接进行代码编写。
5，安装好node.js后，npm具体代码安装
---------步骤二：(Win + R)在控制面板中输入以下命令行-----------
#全局安装 vue-cli 分为两种情况：
一，使用npm，访问国外网站。
输入：npm install --global vue-cli
(这里的npm是访问国外的网站，下载速度很慢。所以，可以使用淘宝镜像的cnpm)
回车等待下载完成，显示如下：
韦德君@LAPTOP-AKTJNVLT MINGW64 /d/泉州时代/学习/vue.js
$ npm install --global vue-cli

added 241 packages from 206 contributors in 150.212s
韦德君@LAPTOP-AKTJNVLT MINGW64 /d/泉州时代/学习/vue.js
二，使用国内网站，淘宝的镜像。
不使用上面国外的npm，改为使用使用淘宝npm镜像的步骤：
1，输入：npm install -g cnpm --registry=https://registry.npm.taobao.org/ + 按回车
显示如下；
韦德君@LAPTOP-AKTJNVLT MINGW64 /d/泉州时代/学习/vue.js
$ npm install -g cnpm --registry=https://registry.npm.taobao.org/
C:\Users\30467\AppData\Roaming\npm\cnpm -> C:\Users\30467\AppData\Roaming\npm\node_modules\cnpm\bin\cnpm
+ cnpm@6.1.0
added 680 packages from 928 contributors in 121.079s
<!-- 如果是重复安装，那么就是进行更新操作，最后一局可能会变成：
updated 2 packages in 74.538s -->
2，输入： cnpm install --global vue-cli + 回车。
显示如下：才算成功安装

<!-- 安装成功，上面是最后一句代码 -->
----------步骤三：使用git打开指定目录，创建webpack模板的新项目----------
如果这里不适用Git工具，那么就必须在命令控制面板中找到指定目录下再执行以下命令
如果node.js 和 npm/cnpm 已经安装完毕，
需要创建新的项目，则直接执行后面的几个步骤即可。有时候会运行失败，不知道是什么情况。
此外，不能在已经创建好的项目中创建另外一个项目，否则直接报错。
-------------------------------------------------
<!-- 下面的：这里必须注意， ? Install vue-router? (Y/n) Y 一定要输入Y，即YES -->
#创建一个基于webpack模板的新项目
输入：vue init webpack my-project
显示如下：
韦德君@LAPTOP-AKTJNVLT MINGW64 /d/泉州时代/学习/vue.js
$ vue init webpack my-project
? Project name (my-project) <!-- 是否把项目命名为(my-project) 直接回车即可(默认肯定) -->
? Project name my-project
? Project description (A Vue.js project) <!-- 是否进行项目描述 直接回车即可(默认肯定) -->
? Project description A Vue.js project
? Author <!-- 是否填写作者 直接回车即可(默认肯定) -->
? Author
? Vue build standalone <!-- 是否独立创建Vue 直接回车即可(默认肯定) -->
? Install vue-router? (Y/n) Y <!-- 这里必须注意，一定要输入Y，即YES -->

npm WARN deprecated browserslist@1.7.7: Browserslist 2 could fail on reading Browserslist >3.0 config used in other tools.
这样项目模板就算创建完毕了 ，ctrl + C 退出命令控制面板。
按完 Ctrl + C 就会跳转到如下：

注意点： vue init webpack my-projectSecond 项目名称不能有大写字母，否则直接报错，如下：
? Project name (my-projectSecond) my-projectSecond
>> Sorry, name can no longer contain capital letters.
----------步骤四：输入下面的几句代码----------
#安装依赖包
1，输入：cd my-project + 回车 没有其他显示，只是换行继续输入下面一句代码。
2，输入：cnpm install + 回车 (淘宝镜像使用) / npm install (下载国外的npm才使用)
显示如下：
