You can use some simple functions like setCookie() and getCookie().
You can set a cookie using the call:
setCookie('myName','value', 3);
function setCookie(name, value, days) { var expires = ""; if (days) { var date = new Date(); date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000)); expires = "; expires=" + date.toUTCString(); } document.cookie = name + "=" + (value || "") + expires + "; path=/"; } function getCookie(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; }
