两种cookie操作方式代码：
1、js原生

        var G = G || {};        G.Cookie = {            Get: function (name) {                var cv = document.cookie.split("; ");                var cva = [], temp;                for (i = 0; i < cv.length; i++) {                    temp = cv[i].split("=");                    cva[temp[0]] = unescape(temp[1]);                }                if (name) return cva[name];                else return cva;            },            Set: function (name, value, expires, path, domain, secure) {                if (!name || !value) return false;                if (name == "" || value == "") return false;                if (expires) {                    if (/^[0-9]+$/.test(expires)) {                        var today = new Date();                        expires = new Date(today.getTime() + expires * 1000).toGMTString();                    } else if (!/^wed, d...{2} w...{3} d...{4} d...{2}:d...{2}:d...{2} GMT$/.test(expires)) {                        expires = undefined;                    }                }                var cv = name + "=" + escape(value) + ";"                       + ((expires) ? " expires=" + expires + ";" : "")                       + ((path) ? "path=" + path + ";" : "")                       + ((domain) ? "domain=" + domain + ";" : "")                       + ((secure && secure != 0) ? "secure" : "");                if (cv.length < 4096) {                    document.cookie = cv;                    return true;                } else {                    return false;                }            },            Del: function (name, path, domain) {                if (!name) return false;                if (name == "") return false;                if (!this.Get(name)) return false;                document.cookie = name + "=;"                                  + ((path) ? "path=" + path + ";" : "")                                  + ((domain) ? "domain=" + domain + ";" : "")                                  + "expires=Thu, 01-Jan-1970 00:00:01 GMT;";                return true;            }        }

2、基于jQuery的$.cookie

    jQuery.cookie = function (name, value, options) {            if (typeof value != 'undefined') { // name and value given, set cookie                options = options || {};                if (value === null) {                    value = '';                    options.expires = -1;                }                var expires = '';                if (options.expires && (typeof options.expires == 'number' || options.expires.toUTCString)) {                    var date;                    if (typeof options.expires == 'number') {                        date = new Date();                        date.setTime(date.getTime() + (options.expires * 24 * 60 * 60 * 1000));                    } else {                        date = options.expires;                    }                    expires = '; expires=' + date.toUTCString(); // use expires attribute, max-age is not supported by IE                }                var path = options.path ? '; path=' + options.path : '';                var domain = options.domain ? '; domain=' + options.domain : '';                var secure = options.secure ? '; secure' : '';                document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');            } else { // only name given, get cookie                var cookieValue = null;                if (document.cookie && document.cookie != '') {                    var cookies = document.cookie.split(';');                    for (var i = 0; i < cookies.length; i++) {                        var cookie = jQuery.trim(cookies[i]);                        // Does this cookie string begin with the name we want?                        if (cookie.substring(0, name.length + 1) == (name + '=')) {                            cookieValue = decodeURIComponent(cookie.substring(name.length + 1));                            break;                        }                    }                }                return cookieValue;            }        };
