Hi Folks,
I want to display error message after submit. Here is my code as below.
@Component({
selector: 'field-error-display',
templateUrl: 'fieldErrorDisplay.component.html',
styleUrls: ['fieldErrorDisplay.component.css']
})
export class FieldErrorDisplayComponent {
@Input() errorMsg: string;
@Input() displayError: boolean;
}
<div *ngIf="displayError">
<div class="error-msg">
<span class="fa fa-close" style="position:relative;top:4px"></span
>{{ errorMsg }}
</div>
</div>
isFieldValid(field: string) {
return !this.form.get(field).valid && this.form.get(field).touched;
}
validateAllFormFields(formGroup: FormGroup): void {
Object.keys(formGroup.controls).forEach(field => {
const control = formGroup.get(field);
if (control instanceof FormControl) {
control.markAsTouched({ onlySelf: true });
} else if (control instanceof FormGroup) {
this.validateAllFormFields(control);
}
});
}
<field-error-display [displayError]="isFieldValid('model')" errorMsg="Please
enter a valid type of vehicle!"></field-error-display>
<p-dropdown [options]="modelVehicleDropDownList" [(ngModel)]=
"selectModelVehicle" placeholder="Select Vehicle" formControlName="model"
filter="filter"></p-dropdown>

In the above screenshot, I just clicked dropdown list without any select
value then got display error message. The error message should not display
because i did not select any value from dropdown list. Other input are fine
such as text and radio button.
I tried many times still no clue. :(
Any idea?
I am waiting for your response.
Thanks in Advance
