Javascript: how would I perform actions on the cookie object in the following function?
if (typeof String.prototype.trimLeft !== "function") {
    String.prototype.trimLeft = function() {
        return this.replace(/^s+/, "");
    };
}
if (typeof String.prototype.trimRight !== "function") {
    String.prototype.trimRight = function() {
        return this.replace(/s+$/, "");
    };
}
function getCookies() {
    var c = document.cookie, v = 0, cookies = {};
    if (document.cookie.match(/^s*$Version=(?:"1"|1);s*(.*)/)) {
        c = RegExp.$1;
        v = 1;
    }
    if (v === 0) {
        c.split(/[,;]/).map(function(cookie) {
            var parts = cookie.split(/=/, 2),
                name = decodeURIComponent(parts[0].trimLeft()),
                value = parts.length > 1 ? decodeURIComponent(parts[1].trimRight()) : null;
            cookies[name] = value;
        });
    } else {
        c.match(/(?:^|s+)([!#$%&'*+-.0-9A-Z^`a-z|~]+)=([!#$%&'*+-.0-9A-Z^`a-z|~]*|"(?:[x20-x7Ex80xFF]|\[x00-x7F])*")(?=s*[,;]|$)/g).map(function($0, $1) {
            var name = $0,
                value = $1.charAt(0) === '"'
                          ? $1.substr(1, -1).replace(/\(.)/g, "$1")
                          : $1;
            cookies[name] = value;
        });
    }
    return cookies;
}
function getCookie(name) {
    return getCookies()[name];
}
