Si es true, useCapture indica que el usuario desea iniciar la captura. Despus de iniciar la captura, todos los eventos del tipo especificado sern lanzados al listener registrado antes de comenzar a ser controlados por algn EventTarget que est por debajo en el arbol DOM del documento.
Nota: For event listeners attached to the event target; the event is in the target phase, rather than capturing and bubbling phases. Events in the target phase will trigger all listeners on an element regardless of the useCapture parameter.
Nota: useCapture became optional only in more recent versions of the major browsers; for example, it was not optional prior to Firefox 6. You should provide that parameter for broadest compatibility.
If true, the listener receives synthetic events dispatched by web content (the default is false for chrome and true for regular web pages). This parameter is only available in Gecko and is mainly useful for the code in add-ons and the browser itself. See Interaction between privileged and non-privileged pages for an example.
En el ejemplo anterior , modifyText() es una listener para los eventos click registrados utilzando addEventListener(). Un click en cualquier parte de la tabla notificara al handler y ejecutara la funcin modifyText().
If an EventListener is added to an EventTarget while it is processing an event, it will not be triggered by the current actions but may be triggered during a later stage of event flow, such as the bubbling phase.
If multiple identical EventListeners are registered on the same EventTarget with the same parameters, the duplicate instances are discarded. They do not cause the EventListener to be called twice, and since the duplicates are discarded, they do not need to be removed manually with the removeEventListener method.
In the example above, the value of this within modifyText() when called from the click event is a reference to the table 't'. This is in contrast to the behavior that occurs if the handler is added in the HTML source:
Nota: JavaScript 1.8.5 introduces the Function.prototype.bind() method, which lets you specify the value that should be used as this for all calls to a given function. This lets you easily bypass problems where it's unclear what this will be, depending on the context from which your function was called. Note, however, that you'll need to keep a reference to the listener around so you can later remove it.
This method replaces the existing click event listener(s) on the element if there are any. Similarly for other events and associated event handlers such as blur (onblur), keypress (onkeypress), and so on.
In the first case, a new (anonymous) function is created at each loop turn. In the second case, the same previously declared function is used as an event handler. This results in smaller memory consumption. Moreover, in the first case, since no reference to the anonymous functions is kept, it is not possible to call element.removeEventListener because we do not have a reference to the handler, while in the second case, it's possible to do myElement.removeEventListener("click", processEvent, false).
