Question

我已经声明了一个简单的形式，并为其分配了一个可观察对象，该可观察对象被映射为返回对象，我在返回之前在控制台中记录了该对象，但值更改从未触发。

comPlanForm= new FormGroup({
    commissionPlanType: new FormControl('', [Validators.required]),
    commissionPlanName: new FormControl('', [Validators.required, Validators.maxLength(150)]),
    commissionPlanDescription: new FormControl('', [Validators.maxLength(150)]),
    payoutSchedule: new FormControl('', [Validators.required]),
    broker: new FormControl('', [Validators.required]),
    trigger: new FormControl('', [Validators.required]),
     waitUntilDays: new FormControl('', [Validators.required]),
    startDate: new FormControl('', [Validators.required]),
    endDate: new FormControl('')});

comPlanForm$ = this.comPlanForm.valueChanges.pipe(
    map(value => { 
        const plan= new CommissionPlanRequest(null,null,value.commissionPlanName, value.commissionPlanDescription,
        value.commissionPlanType, value.startDate, value.endDate, value.payoutSchedule, value.broker, null,
        new PlanTrigger(null,value.waitUntilDays,value.trigger),[]) 
        return plan;
    }),
    tap(x=>console.log(x))
);

我没有ngOnInit，我也尝试过将console.log放入map函数本身，但不走运，关于为什么我的值更改未触发的任何想法吗？

Answer 1

 this.comPlanForm.valueChanges.subscribe(value =>
  { 
    const plan= new CommissionPlanRequest(null,null,value.commissionPlanName, value.commissionPlanDescription,
    value.commissionPlanType, value.startDate, value.endDate, value.payoutSchedule, value.broker, null,
    new PlanTrigger(null,value.waitUntilDays,value.trigger),[]) 
    this.comPlanForm$ = plan;
}

）;
