js-cookie的用法

cookie的做用無需多言，本身封裝一個cookie，不停地複製黏貼頁頗爲麻煩，在這裏，有npm爲咱們封裝好的插件js-cookie: https://www.npmjs.com/package/js-cookie。

引用方法:

1.直接飲用cdn：<script src="https://cdn.jsdelivr.net/npm/js-cookie@2/src/js.cookie.min.js"></script>

2.本地下載下來後：<script src="/path/to/js.cookie.js"></script>

3.模塊化開發時: import Cookies from 'js-cookie'

使用方法：

 

Basic Usage

Create a cookie, valid across the entire site:

Cookies.set('name', 'value');
Create a cookie that expires 7 days from now, valid across the entire site:

Cookies.set('name', 'value', { expires: 7 });
Create an expiring cookie, valid to the path of the current page:

Cookies.set('name', 'value', { expires: 7, path: '' });
Read cookie:

Cookies.get('name'); // => 'value'
Cookies.get('nothing'); // => undefined
Read all visible cookies:

Cookies.get(); // => { name: 'value' }
Delete cookie:

Cookies.remove('name');
Delete a cookie valid to the path of the current page:

Cookies.set('name', 'value', { path: '' });
Cookies.remove('name'); // fail!
Cookies.remove('name', { path: '' }); // removed!
IMPORTANT! when deleting a cookie, you must pass the exact same path and domain attributes that was used to set the cookie, unless you're relying on the default attributes.

Note: Removing unexisting cookie does not raise any exception nor return any value
