This example is a little helper class to make and erase cookies in javascript. I will first post the Cookies.js script that will create, read, and erase cookies from your browser.
Cookies.js

function COOKIE () {
this.createCookie = function (name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}
,
this.readCookie = function (name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
,
this.eraseCookie = function(name) {
this.createCookie(name,"",-1);
}
}
Then you just include this javascript in a webpage and create the object and then you can call the different functions as you will. Here is an example HTML file using it. This file just pretty much tests out the Cookies.js file.
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>profile</title>
</head>
<body>
<script src="Cookies.js"></script>
<h1>this is a test of Cookies</h1>
<h2 id = "cook"></h2>
<input id = "cookiename" type="text" placeholder="cookie name..."></input>
<input id = "cookievalue" type="text" placeholder="cookie value..."></input>
<input id = "days" type = "number" placeholder="number of days"></input>
<button onclick="buttonClick()">Create Cookie</button>
<br>
<input id = "getcookie" placeholder="cookie name"></input>
<button onclick="getCookie()">Read Cookie</button>
<br>
<input id = "erase" placeholder="cookie name"></input>
<button onclick="deleteCookie()">Erase Cookie</button>
<p id= "paragraph"></p>
<script>
var Cookie = new COOKIE();
function buttonClick(){
var name = document.getElementById("cookiename").value;
var value = document.getElementById("cookievalue").value;
var days = document.getElementById("days").value;
Cookie.createCookie(name,value,days);
document.getElementById("paragraph").innerText = "Cookie Created: " + name + "=" + value + ";" + days;
}
function getCookie(){
var name = document.getElementById("getcookie").value;
var cookie = Cookie.readCookie(name);
document.getElementById("paragraph").innerText = "Cookie Read: " + name + "=" + cookie;
}
function deleteCookie(){
var name = document.getElementById("erase").value;
Cookie.eraseCookie(name);
document.getElementById("paragraph").innerText = "Cookie Erased: " + name;
}
</script>
</body>
</html>
and that’s pretty much it for this article. Maybe you can get some use out of this. I hope you enjoyed this article.
