function getTime() {
            var time = new Date();
            var hour = time.getHours();
            var minute = time.getMinutes();
            var seconds = time.getSeconds();
            if (hour < 10) {
                hour = '0' + hour;
            }
            if (minute < 10) {
                minute = '0' + minute;
            }
            if (seconds < 10) {
                seconds = '0' + seconds;
            }
            return '现在是' + hour + ':' + minute + ':' + seconds;
