Join Justin Schwartzenberger for an in-depth discussion in this video Event binding, part of Angular 2 Essential Training.
- [Instructor] The event binding templates syntax in Angular…allows you to easily wire up event handlers…from within your component templates.…You can wire up native DOM element events,…as well as custom events you create…for your components to emit.…Let's take a look at how you wire up to native events.…Our media-item.component.html has a delete link.…Let's add some click functionality to that.…Where property binding makes use of the square brackets,…event binding makes use of the parenthesis.…
So on the <a> tag element for the delete,…we can add the event named click,…wrapped with parenthesis,…and set it equal to a statement in quotes…that will be evaluated.…Let's bind this to a function call onDelete.…Notice that we use the term click here…and not onClick.…Angular has a pattern for native DOM elements…where it is looking for the event name…without the "on".…
So any native DOM event…that is named "onX",…you would bind to it by leaving the "on" prefix off.…Angular is expecting the onDelete method…to be available in the execution context.…
