js中Cookie运用

<---------------------------设置Cookie--------------------> 

function SetCookie(name, value, expires, path, domain, secure) {
            var expDays = expires * 24 * 60 * 60 * 1000;
            var expDate = new Date();
            expDate.setTime(expDate.getTime() + expDays);
            var expString = ((expires == null) ? "" : (";expires=" + expDate.toGMTString()))
            var pathString = ((path == null) ? "" : (";path=" + path))
            var domainString = ((domain == null) ? "" : (";domain=" + domain))
            var secureString = ((secure == true) ? ";secure" : "")
            document.cookie = name + "=" + escape(value) + expString + pathString + domainString + secureString;
        }

 

<-------------------------读取Cookie------------------------------------>

        function GetCookie(name) {
            var result = "";
            var myCookie = document.cookie + ";";
            var searchName = name + "=";
            var startOfCookie = myCookie.indexOf(searchName);
            var endOfCookie;
            if (startOfCookie != -1) {
                startOfCookie += searchName.length;
                endOfCookie = myCookie.indexOf(";", startOfCookie);
                result = unescape(myCookie.substring(startOfCookie, endOfCookie));
            }
            return result;
        }
