一、js cookie   使用時把此段代碼引入頁面

設定cookie

Cookies(name, value); || Cookies.set(name, value);  //name：所存cookie的名稱；value：名稱對應的值

Cookies(name1, value1); || Cookies.set(name1, value1);

Cookies(name,value, { expires: 7 }); || Cookies.set(name,value, { expires: 7 });  // 設定cookie失效時間，單位：天

Cookies(name,value, { expires: 7,path:"/路徑",domain: "網域名稱"}); || Cookies.set(name,value, { expires: 7,path:"/路徑",domain: "網域名稱"});// 設定cookie,包括有效期間 路徑 網域名稱等

讀取cookie

Cookies(); || Cookies.get();  //讀取所有cookie,輸出的是對象==>{name:value, name1:value1}

Cookies(name); || Cookies.get(name);  //讀取對應名稱的cookie==>value

刪除cookie

Cookies(name:""); //將cookie清空

Cookie.remove(name:""); //刪除cookie 對應的cookie名稱也刪除
