I am having trouble viewing the input value on my Angular5 form

Here is the HTML code snippet that I've written:

<input type="text" name="fechainscripcion" #fechainscripcion="ngModel" [(ngModel)]="alumno.fechainscripcion" value="{{today | date:'dd/MM/yyyy'}}" class="form-control" />

This is a segment of my component code:

this.today = Date.now();
this.title = 'Añadir';
this.alumno = new Alumno('','','','','','',null,'','','Alta');

Currently, the fechainscripcion value in the alumno array is set to null. However, I am aiming to display the value "{{today | date:'dd/MM/yyyy'}}" within the input field.

Answer №1

To start, remove the directive [(ngModel)] and instead use [value]="..."

When using value without the '[]', Angular will set it to exactly what is in the quotes. However, in this scenario, it is not necessary as ngModel also sets the value to null.

If you wish for the input to display the current date by default, assign that date in the Alumno constructor rather than null.

Answer №2

{{}} should be utilized for interpolation in this scenario. It is unnecessary because the input element is being bound with ngModel. You can either eliminate the section: 

[(ngModel)]="alumno.fechainscripcion"

Alternatively, you can assign the date value directly to alumno.
