Angular2: Detect form changes
angular, angular2-forms, typescript
Solution
You can add separate subscriptions for FormControl a and b.
this.heroForm.controls["a"].valueChanges.subscribe(data => {
// Do something
});
this.heroForm.controls["b"].valueChanges.subscribe(data => {
// Do something
});
Problem
In Angular2 4.0 I have a `FormGroup` looking like this: ``` this.form = this._fb.group({ a: ['', [Validators.required]], b: ['', [Validators.required]], c: ['', [Validators.required]], }); ``` Is it possible to subscribe `valueChanged` on individual fields? I dont want to detect changes on input `c`, so the below approach does not work: ``` this.form.valueChanges.debounceTime(400).subscribe(data => { // Do something }); ```
