JavaScript根据Cookie名称获取Cookie值

一、函数封装

        //获取指定名称的cookie的值
        function getcookie(objname) {
            var arrstr = document.cookie.split("; ");
            for (var i = 0; i < arrstr.length; i++) {
                var temp = arrstr[i].split("=");
                if (temp[0] == objname) return unescape(temp[1]);
            }
        }
