9.JS计算俩个日期之间相差的天数，过滤节假日和周末

本来想着找下有没有节假日的插件，可是找不到。所以，我就手写节假日了。

如果对路过的你有帮助，请随手点个赞。

// 法定节假日festival=["2018-12-30","2018-12-31","2019-01-01","2019-02-03","2019-02-04","2019-02-05","2019-02-06","2019-02-07","2019-02-08","2019-02-09","2019-02-10","2019-02-11","2019-04-05","2019-04-06","2019-04-07","2019-05-01","2019-05-02","2019-05-03","2019-05-04","2019-06-07","2019-06-08","2019-06-09","2019-09-13","2019-09-14","2019-09-15","2019-10-01","2019-10-02","2019-10-03","2019-10-04","2019-10-05","2019-10-06","2019-10-07","2020-01-01","2020-01-24","2020-01-25","2020-01-26","2020-01-27","2020-01-28","2020-01-29","2020-01-30","2020-01-31","2020-02-01","2020-02-02","2020-04-04","2020-04-05","2020-04-06","2020-05-01","2020-05-02","2020-05-03","2020-05-04","2020-05-05","2020-06-25","2020-06-26","2020-06-27","2020-10-01","2020-10-02","2020-10-03","2020-10-04","2020-10-05","2020-10-06","2020-10-07","2020-10-08","2021-01-01","2021-02-11","2021-02-12","2021-02-13","2021-02-14","2021-02-15","2021-02-16","2021-02-17","2021-02-26","2021-04-02","2021-04-03","2021-04-04","2021-04-30","2021-05-01","2021-05-02","2021-06-12","2021-06-13","2021-06-14","2021-06-12","2021-09-19","2021-09-20","2021-09-21","2021-10-01","2021-10-02","2021-10-03","2021-10-04","2021-10-05","2021-10-06","2021-10-07","2022-01-01","2022-01-31","2022-02-01","2022-02-02","2022-02-03","2022-02-04","2022-02-05","2022-02-06","2022-04-03","2022-04-04","2022-04-05","2022-04-30","2022-05-01","2022-05-02","2022-06-03","2022-06-04","2022-06-05","2022-09-09","2022-09-10","2022-09-11","2022-10-01","2022-10-02","2022-10-03","2022-10-04","2022-10-05","2022-10-06","2022-10-07"];//需要上班的周末varweekendWorkDay=["2018-12-29","2019-02-02","2019-09-29","2019-10-12","2019-04-28","2019-05-05","2020-01-19","2020-04-26","2020-05-09","2020-06-28","2020-09-27","2020-10-10","2021-02-07","2021-02-20","2021-09-18","2021-10-09","2021-10-10"];
