Event.currentTarget
Identifies the current target for the event, as the event traverses the DOM. It always refers to the element the event handler has been attached to as opposed to event.target
which identifies the element on which the event occurred.
Example
event.currentTarget
is interesting to use when attaching the same event handler to several elements.
function hide(e){ e.currentTarget.style.visibility = "hidden"; // When this function is used as an event handler: this === e.currentTarget } var ps = document.getElementsByTagName('p'); for(var i = 0; i < ps.length; i++){ ps[i].addEventListener('click', hide, false); } // click around and make paragraphs disappear

[1] On Internet Explorer 6 through 8, the event model is different. Event listeners are attached with the non-standard EventTarget.attachEvent
method. In this model, there is no equivalent to event.currentTarget
and this
is the global object. One solution to emulate the event.currentTarget
feature is to wrap your handler in a function calling the handler using Function.prototype.call
with the element as a first argument. This way, this
will be the expected value.
