我在车辆年问题上写了一个指令validVehicleyear，这个我想调用年份更改并为Vehicle make设置新选项，但它不起作用。

I wrote a directive validVehicleyear on class at Vehicle year question, this i want to call on change of year and set new options for Vehicle make, but it not working.

Class =form-control ** valid-vehicleyear ** ng-not-empty ng-dirty ng-valid-parse ng-valid ng-valid-required ng-touching

推荐答案

您忘记申报指令功能

.directive（'validVehicleyear'，validVehicleyear）
