angularjs - angular2 validating multiple controls in one validator -
i validate loan calculation form depending on choices of end user.
for example , if user clicks red button(that specific loan type) second text input should 36 max.
therefore access values of more 1 control during validation.
to achieve ve declared ngmodelgroup inside form , custom validator class.
the problem when validator hit can not access values of user controls inside validate method.
thanks in advance.
