One of the most common things that most web developers would do is cookie management.

Was pawing at some JavaScript and made a simple cookie management class in JavaScript that does basic cookie management like:

• setCookie
• getCookie
• removeCookie
• getAll
• removeAll

Okies, so now enough of talking, here is the silly code:

/*
 * @author      Hemanth.HM 
 * @version     0.1
 * @desc        JavaScript cookie management.
 * @license     GNU GPLv3 
 */

manageCookie = {
    /**
     * Set a cookie's value
     * @param  name  string  Cookie's name.
     * @param  value string  Cookie's value.
     * @param  days  int     Number of days for expiry.
     */
    setCookie: 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=/";
    },

    /**
     * Get a cookie's value
     * @param  name  string  Cookie's name.
     * @return value of the Cookie.
     */
    getCookie: function(name) {
        var coname = name + "=";
        var co = document.cookie.split(';');
        for (var i = 0; i < co.length; i++) {
            var c = co[i];
            c = c.replace(/^\s+/, '');
            if (c.indexOf(coname) == 0) {
                return c.substring(coname.length, c.length);
            }
        }
        return null;
    },

    /**
     * Removes a cookie
     * @param  name  string  Cookie's name.
     */
    removeCookie: function(name) {
        manageCookie.setCookie(name, "", -1);
    },

    /**
     * Returns an object with all the cookies.
     */
    getAll: function() {
        var splits = document.cookie.split(";");
        var cookies = {};
        for (var i = 0; i < splits.length; i++) {
            var split = splits[i].split("=");
            cookies[split[0]] = unescape(split[1]);
        }
        return cookies;
    },

    /**
     * Removes all the cookies
     */
    removeAll: function() {
        var cookies = manageCookie.getAll();
        for (var key in cookies) {
            if (cookies.hasOwnProperty(key)) {
                manageCookie.removeCookie(key);
            }
        }
    }
};
