Video: target Event Property - W3School

Definition and Usage The target event property returns the element that triggered the event. The target property gets the element on which the event originally occurred, opposed to the currentTarget property, which always refers to the element whose event listener triggered the event The target property of the Event interface is a reference to the object onto which the event was dispatched. It is different from Event.currentTarget when the event handler is called during the bubbling or capturing phase of the event

Event Target, Event Type und Timestamp Jedes Javascript-Event bringt Informationen mit, die das Ereignis und seinen aktuellen Zustand beschreiben. Die Eigenschaften eines Events identifizieren das auslösende Element (event target), den Typ des Events (event type) und den Zeitpunkt des Eintreffens (timestamp) version added: 1.0 event.target The target property can be the element that registered for the event or a descendant of it. It is often useful to compare event.target to this in order to determine if the event is being handled due to event bubbling. This property is very useful in event delegation, when events bubble How to set the EventTarget of a Event. var myObj = {foo: 'bar'}; var event = new Event ('eventName'); event.target = myObj; Will result in the following error: Uncaught TypeError: Cannot set property target of #<Event> which has only a getter Since we already talked about the event.target property, there is another property called event.currentTarget in JavaScript event. It can be very confused by just reading about them on JavaScript.. We need to understand event bubbling before we can understand the difference between target and currentTarget. When an event is raised on an element, the event handler on that element is invoked. The event handler on its parent element is then invoked and so on. So, the event bubbles up the DOM tree

Creates a new event: composedPath() Returns the event's path: currentTarget: Returns the element whose event listeners triggered the event: defaultPrevented: Returns whether or not the preventDefault() method was called for the event: eventPhase: Returns which phase of the event flow is currently being evaluated: isTrusted: Returns whether or not an event is truste Use of target and relatedTarget The relatedTarget property for the mouseover event holds the node that the mouse was previously over.

You can do the same with $ (event.target)

Event.target - Web APIs MD

Element, Document, and Window are the most common event targets, but other objects can be event targets, too. For example XMLHttpRequest, AudioNode, AudioContext, and others.

É diferente de event.currentTarget quando o manipulador de eventos é chamado durante a fase de borbulhagem ou captura do evento event.target tells where the event started. Suppose there's an event which shows an alert on click of the element. This event has been attached to the body. Now when the user clicks on the strong.. Event bubbling is an approach to listening for events that's better for performance and gives you a bit more flexibility. Instead of adding event listeners to specific elements, you listen to all events on a parent element (often the document or window). Events within that element bubble up, and you can check to see if the element that triggered the event (the event.target) matches the. La propiedad target de la interfaz del event.currentTarget es una referencia al objeto en el cual se lanzo el evento. Es diferente de event.currentTarget donde el controlador de eventos (event handler) es llamado durante la fase de bubbling or capturing del evento

Mit der Schnittstelle EventTarget können Ereignis-Handler registriert und auch wieder entfernt werden. Die Schnittstelle gilt für alle Knoten JavaScript event.target vs event.currentTarget in 30 seconds. Example. In the example below, there's a click event bound to the outer box, with an id thebox. There's an inner box with an id hello. Since hello is within thebox, clicking on hello will trigger the click event bound to thebox. But you can also click in the empty space outside of hello to trigger the event as well. Just click stuff.
