I use @Input() to pass an ID from another component, but I initialize the ID with a number like this:
@Input() ServiceId: number=21;
How can I initialize the input with that number from the initial component? Do I directly assign a variable to @Input()?
You send the data to the child component via the parent component's template.
For your case, your parent component's template could look something like this:
<my-sub-component [ServiceId]="21"></my-sub-component>
If your parent component has a property called, e.g., myServiceId, you can pass that in as well:
<my-sub-component [ServiceId]="myServiceId"></my-sub-component>
Take a look at the documentation here for more information.
