There could last other ways to usage cookies but a server could practise this amongst JavaScript. Below nosotros convey a elementary script that tin ship away last used every bit many times nosotros desire , fifty-fifty for dissimilar purposes. Basically , what the next script does is to practise 3 functions: the kickoff 1 is to laid a cookie , the 2nd 1 is to read it , in addition to the concluding 1 is to erase it. We tin ship away apply it inward Blogger past times accessing the template HTML in addition to add together it only earlier the tag:
Once done , inward companionship to laid a cookie , nosotros entirely require to set the mention in addition to the value inward quotes when nosotros telephone telephone the function. Additionally , nosotros volition laid the croak appointment past times getting the electrical current Time (in milliseconds) in addition to add together the required give away of minutes (in milliseconds):
var expiration = novel Date();
expiration.setTime(expiration.getTime() + 10000); //Expire later 10 seconds
setCookie(“cookiename” ,”hello” ,expiration);
}
The inward a higher identify code sets a cookie called cookiename , amongst the hello value in addition to laid its croak appointment to 10 seconds later it has been laid (10000 milliseconds = 10 seconds). If nosotros desire to restore the value of this cookie , so nosotros should usage the 2nd role amongst the cookie name:
var checkCookie = getCookie(“cookiename“);
By adding this code below the taag , nosotros created a cookie amongst the value ‘hello‘ which tin ship away last shown on the covert if nosotros desire to. The cookie volition disappear later 10 seconds:
The erase role is used inward the same agency every bit the 1 for reading only past times clicking on the mention of the cookie.

Use ‘domain’ on the JavaScript cookie if yous are using it on a subdomain , where the cookie is onslaught the widgets subdomain , but yous require it to last accessible over the whole yoursite.com domain.
The combination of these 3 functions volition allow us to grip cookies for specific purposes , every bit nosotros volition meet inward the close future.
