Suppose I have a controller where I'm emitting an event:
@Output() somethingUpdated = new EventEmitter();and in a method:
***
this.somethingUpdated.emit();
***
In the view, I've added:
(somethingUpdated)="somethingUpdated($event)"In a directive, I defined:
@HostListener('somethingUpdated', ['$event'])
somethingUpdated() {
console.log('somethingUpdated');
}
However, this setup doesn't seem to be working.
What am I doing wrong?
Instead of binding the handler to an event on the document, make sure it is receiving events from the specific output source that you have defined.
Remember, the output source is what emits the event in this case.
If you need guidance on using Outputs in Angular (2+), there are plenty of examples available to help you get started in the right direction.
Take a look at the documentation for more information: https://angular.io/docs/ts/latest/cookbook/component-communication.html
Pay special attention to the section titled "Parent listens for child event."
The format used when binding to a document event could be handy if, for example, you wanted a handler to trigger whenever the document was resized.
