Set cookies

Cookies (name, value); | | Cookies.set (name, value);  Name: The names of the stored cookies; value: The values that correspond to the names

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

Cookies (Name,value, {expires:7}); | | Cookies.set (Name,value, {expires:7});  Set the cookie expiration time, unit: Days

Cookies (Name,value, {expires:7,path: "/path", Domain: "domain name"}); | | Cookies.set (Name,value, {expires:7,path: "/path", Domain: "domain name"});//set cookies, including expiration path domain name, etc.

Read cookies

Cookies (); | | Cookies.get ();  Read all cookies, output object ==>{name:value, name1:value1}

Cookies (name); | | Cookies.get (name);  Read the cookie==>value of the corresponding name

Delete Cookies

Cookies (Name: ""); Empty the cookie

Cookie.remove (Name: ""); Delete cookie corresponding to cookie name also deleted
