I'm attempting to pass a formarray to a child component in order to display the values within the formarray there. Here is my current code, but I am struggling to figure out how to show the formarray values in the child component.
app.component.html
<div [formGroup]="userForm">
<div formArrayName="users">
<div *ngFor="let user of users.controls; let i = index">
<input type="text" placeholder="Enter a Room Name" [formControlName]="i">
</div>
</div>
</div>
<button (click)="addUser()">Add Room</button>
<title [users]="users"></title>
app.component.ts
userForm: FormGroup;
constructor(private fb: FormBuilder) {}
public get users(): any {
return this.userForm.get('users') as FormArray;
}
ngOnInit() {
this.userForm = this.fb.group({
users: this.fb.array([this.fb.control('')])
});
}
addUser() {
this.users.push(this.fb.control(''));
}
title.component.html
<div *ngFor="let user of users.controls">{{ user.value }}</div>
title.component.ts
@Input() users;
ngOnChanges(changes) {
console.log(changes);
}
Unfortunately, the above code is not successfully displaying the formarray values in the child component.
