js-cookie插件是一個(gè)JS操作cookie的插件，源文件只有3.34 KB，非常輕量級(jí)，js-cookie也支持npm和Bower安裝和管理，下面看看js-cookie的具體用法

1、引入js-cookie.js

1.直接飲用cdn：
<script src="https://cdn.jsdelivr.net/npm/js-cookie@2/src/js.cookie.min.js"></script>
2.本地下載下來后：
<script src="/path/to/js.cookie.js"></script>
3.模塊化開發(fā)時(shí):
$ npm install js-cookie --save
import Cookies from 'js-cookie'

2、js-cookie.js常用的API和方法

a、設(shè)置cookie

Cookies.set('name', 'value', { expires: 7, path: '' });//7天過期
Cookies.set('name', { foo: 'bar' });//設(shè)置一個(gè)json

b、讀取cookie

Cookies.get('name');//獲取cookie
Cookies.get(); #讀取所有的cookie

c、刪除cookie

Cookies.remove('name'); #刪除cookie時(shí)必須是同一個(gè)路徑。
