I recently encountered an error message stating "Object is possibly null" while working on the changePageSize method in book-store.component.html. It seems like I need to initialize the object within the class, but I'm not familiar with how to do that. Can someone provide guidance on this issue? I am relatively new to both Typescript and Angular.
$event.target is of type EventTarget, and does not have a value field.
This is likely the cause of your problem.
To resolve this issue, you will need to correctly cast $event.target to the appropriate type.
// template
<select ... (change)="changePageSize($event)">...</select>
// component
changePageSize(event: Event): void {
const element = event.target as HTMLInputElement;
const value = element.value;
}
