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.

enter image description here

import { directive, forwardref, input } '@angular/core'; import { abstractcontrol, ng_validators, validator } '@angular/forms';  @directive({      selector: '[kredivadesayisi-validator]',     providers: [         {             provide: ng_validators,             multi: true,             useexisting: forwardref(() => kredivadesayisivalidator)         }     ]  }) export class kredivadesayisivalidator implements validator {      @input('kredivadesayisi-validator') msg = 'hata mesaj';      validate(c: abstractcontrol): { [key: string]: } { console.log('console hit'); // displayed on console         return (group) => {             console.log('valid');             if (group) {  //always skipped                 (let ctrl in group.controls) {                     console.log('group'+group.controls[ctrl].value);                  }             }             return null;         }      }   }
