控制器:
model.Register.Country = new SelectList(manager.GetCountries(), "Id", "Name");
model.Register.Region = new SelectList(manager.GetRegions(model.Register.SelectCountryId), "Id", "Name");
model.Register.WebTypeOfLicense = new SelectList(CommonDbService.GetAllLicense(), "Id", "Name");
model.Register.City = new SelectList(manager.GetCities(model.Register.SelectRegionId), "Id", "Name");
功能:
IEnumerable<ICountry> GetAllCountries();
ICountry GetCountry(int countryId);
IEnumerable<IRegion> GetRegions(int countryId);
IRegion GetRegion(int regionId);
IEnumerable<ICity> GetCities(int regionId);
ICity GetCity(int cityId);
主要思想是,當我選擇的國家獲得國家,當我點擊狀態,以獲得城市.. 。國家recive國家的id,所以我需要用國家的id填充狀態來獲得國家,然後引用recive狀態的國家ID來填充城市
