   * 日期对象转为日期字符串
   * @param date 需要格式化的日期对象
   * @param sFormat 输出格式,默认为yyyy-MM-dd                        年:y,月:M,日:d,时:h,分:m,秒:s
   * @example  dateFormat(new Date())                               "2017-02-28"
   * @example  dateFormat(new Date(),'yyyy-MM-dd')                  "2017-02-28"
   * @example  dateFormat(new Date(),'yyyy-MM-dd HH:mm:ss')         "2017-02-28 13:24:00"   ps:HH:24小时制
   * @example  dateFormat(new Date(),'yyyy-MM-dd hh:mm:ss')         "2017-02-28 01:24:00"   ps:hh:12小时制
   * @example  dateFormat(new Date(),'hh:mm')                       "09:24"
   * @example  dateFormat(new Date(),'yyyy-MM-ddTHH:mm:ss+08:00')   "2017-02-28T13:24:00+08:00"
   * @example  dateFormat(new Date('2017-02-28 13:24:00'),'yyyy-MM-ddTHH:mm:ss+08:00')   "2017-02-28T13:24:00+08:00"
