句法

const theTarget = someEvent.target;

EventTarget

范例

event.target property can be used in order to implement event delegation .

// Make a list
const ul = document.createElement('ul');
document.body.appendChild(ul);
const li1 = document.createElement('li');
const li2 = document.createElement('li');
ul.appendChild(li1);
ul.appendChild(li2);
function hide(evt) {
  // e.target refers to the clicked <li> element
  // This is different than e.currentTarget, which would refer to the parent <ul> in this context
  evt.target.style.visibility = 'hidden';
}
// Attach the listener to the list
// It will fire when each <li> is clicked
ul.addEventListener('click', hide, false);

Compatibility notes

On IE 6–8, the event model is different. Event listeners are attached with the non-standard EventTarget.attachEvent() 方法。

In this model, the event object has a Event.srcElement property (instead of the target property) and it has the same semantics as Event.target .

function hide(evt) {
  // Support IE6-8
  var target = evt.target || evt.srcElement;
  target.style.visibility = 'hidden';
}
