Ticu, daudziem būs noderīgi.

 

Lūk kods kā apstrādāt (pievienot , lasīt , dzēst) cepumiņus ar Js palīdzību.

 

function createCookie(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=/";
}

function readCookie(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;
}
function eraseCookie(name) {
createCookie(name,"",-1);
}

Pats sev uzrakstīju šādu risinājumu. OOP FTW.

var cookie: {
/**
 * Atgriež cepumu ar norādīto nosaukumu.
 *
 * @param	string	name	cookie name
 * @param	mixed	def		optional default value, false by default
 */
get: function(name, def){
	var r = new RegExp(name+"=([^;]+)", "i");
	var m = document.cookie.match(r);
	return m ? m[1] : (typeof def == "undefined" ? false : def);
},
/**
 * Uzseto cepumu.
 *
 * @param	string	name	cookie name
 * @param	string	value	cookie value
 * @param	int		expire	optional expiration time (seconds from now), 0 by default (end of session)
 * @param	string	path	optional cookie path, current by default
 */
set: function(name, value, expire, path){
	var c = name+"="+value;
	if(typeof expire != "undefined"){
		var exd = new Date();
		exd.setDate(exd.getDate()+expire);
		c+= ";expires="+exd.toUTCString();
	}
	if(typeof path != "undefined") c+= ";path="+path;
	document.cookie = c;
}
};

cookie.set('aaa', '123');
cookie.get('aaa'); // string 123
cookie.get('bbb'); // bool false
cookie.get('ccc', '321'); // string 321
cookie.set('aaa', '', -1);
cookie.get('aaa'); // bool false
