Is it possible to transfer data from a template to a component without the need for an event trigger like a button or form submission? For instance, in the code snippet provided, how can we pass the 'item' from the 'items' array to the component?
items.html
<div *ngFor="let item of items"></div>
items.component.ts
onInit(item) {
console.log(item);
}
If you have a list of items in your component and want to display the name of each item using a function, you could do something like this:
<div *ngFor="let item of items">
{{showName(item)}}
</div>
In your TypeScript file:
public items = [ { id: 1, name: 'apple' }, { id: 2, name: 'banana' } ];
showName(item: any): void {
console.log(item);
return item.name;
}
