Cookie Getter/Setter using javascript?

/** * Gets or sets cookies * @param name * @param value (null to delete or undefined to get) * @param options (domain, expire (in days)) * @return value or true */ _.cookie = function(name, value, options) { if (typeof value === “undefined”) { var n, v, cookies = document.cookie.split(“;”); for (var i = 0; i < cookies.length; i++) { n = $.trim(cookies[i].substr(0,cookies[i].indexOf(“=”))); v = cookies[i].substr(cookies[i].indexOf(“=”)+1); if (n === name){ return unescape(v); } } } else { options = options || {}; if (!value) { value = “”; options.expires = -365; } else { value = escape(value); } if (options.expires) { var d = new Date(); d.setDate(d.getDate() + options.expires); value += “; expires=” + d.toUTCString(); } if (options.domain) { value += “; domain=” + options.domain; } if (options.path) { value += “; path=” + options.path; } document.cookie = name + “=” + value; } };
