Topic: Using Multiselect with Reactive Forms and updatedOn property doesn't work

dimitribocquet pro asked 6 years ago


I use updateOn (blur) property on my Reactive Form, and the multiselect doesn't update the values. But without updateOn, it works. Of course, I'd like to make it work with updateOn property. Here is my code : <form [formGroup]="form" (ngSubmit)="onSubmit()"> <div class="md-form"> <mdb-select ngDefaultControl [options]="optionsSelect" [multiple]="true" placeholder="Choose an option" formControlName="options"></mdb-select> </div> <div class="text-center"> <button class="btn btn-default waves-light" mdbWavesEffect [disabled]="form.invalid" >Submit</button> </div> </form> <pre> {{ form.value | json }} </pre> export class MyComponent implements OnInit { optionsSelect = [{ value: '1', label: 'Today' }, { value: '2', label: 'Yesterday' }, { value: '3', label: 'Last 7 days' }, { value: '4', label: 'Last 30 days' }, { value: '5', label: 'Last week' }, { value: '6', label: 'Last month' } ]; form: FormGroup; constructor( private _fb: FormBuilder, ) { } ngOnInit() { this.initForm(); } initForm() { // updateOn issue : https://github.com/angular/angular/issues/19163#issuecomment-396947839 const tmpFGroup = this._fb.group({ options: [[], []], }); // Works this.roleModelForm = new FormGroup(tmpFGroup.controls); // Doesn't Work // this.roleModelForm = new FormGroup(tmpFGroup.controls, { updateOn: 'blur' }); } onSubmit() { console.log('submitted', this.form.value); } }
