ember.js - how to watch specified `properties` in `router` and react accordinlgy? -

-



in app, user setting 6 seperate digits. can delete/re-enter/enter values in input. controller sending values router.

when router watches properties, take user next page. question how watch properties ( specified properties ) , react accordingly?

here router code ( snippet ):

export default ember.route.extend({     otp1:null,     otp2:null,     otp3:null,     otp4:null,     otp5:null,     otp6:null,      mywatcher(){         console.log('all properties available, enable next');     },      setupcontroller(controller,model) {         this._super(...arguments);         this.controllerfor('auth-page.credit-card.credit-cardno').set('enablenext', false);      },      actions:{         setupcardnumber( number, index ){             this.set('opt'+index, number ); //setting values             console.log( 'setting', this.get('opt'+index) );//gets property         }     } }

as far understand code, create if-statement:

setupcardnumber( number, index ){     if (this.get('otp1') &&         this.get('otp2') &&         this.get('otp3') &&         this.get('otp4') &&         this.get('otp5') &&         this.get('otp6') ) {         this.transitionto('next-page');     } }

i advice create map or something, code tends unmaintainable rather quickly.
