Método HTML DOM removeEventListener()

❮ O Objeto Elemento

Exemplo

Remova um evento "mousemove" que foi anexado com o método addEventListener():

// Attach an event handler to <div>
document.getElementById("myDIV").addEventListener("mousemove", myFunction);

// Remove the event handler from <div>
document.getElementById("myDIV").removeEventListener("mousemove", myFunction);

Definição e uso

O método removeEventListener() remove um manipulador de eventos que foi anexado com o método addEventListener() .

Nota: Para remover manipuladores de eventos, a função especificada com o método addEventListener() deve ser uma função externa, como no exemplo acima (myFunction).

Funções anônimas, como " element .removeEventListener(" event ", function(){ myScript });" não funciona.


Suporte ao navegador

Os números na tabela especificam a primeira versão do navegador que oferece suporte total ao método.

Method
removeEventListener() 1.0 9.0 1.0 1.0 7.0

Sintaxe

element.removeEventListener(event, function, useCapture)

Valores de parâmetro

Parameter Description
event Required. A String that specifies the name of the event to remove.

Note: Do not use the "on" prefix. For example, use "click" instead of "onclick".

Tip: For a list of all HTML DOM events, look at our complete HTML DOM Event Object Reference.
function Required. Specifies the function to remove.
useCapture Optional. A Boolean value that specifies the event phase to remove the event handler from.

Possible values:
  • true - Removes the event handler from the capturing phase
  • false- Default. Removes the event handler from the bubbling phase
Note: If the event handler was attached two times, one with capturing and one bubbling, each must be removed separately.


Detalhes técnicos

Versão DOM: Eventos DOM Nível 2
Valor de retorno: Sem valor de retorno
Registro de alterações: O parâmetro useCapture tornou-se opcional no Firefox 6 e Opera 12.0 (sempre foi opcional para Chrome, IE e Safari)

Mais exemplos

Exemplo

Para navegadores que não suportam o método removeEventListener(), você pode usar o método detachEvent().

Este exemplo demonstra uma solução entre navegadores:

var x = document.getElementById("myDIV");
if (x.removeEventListener) {                   // For all major browsers, except IE 8 and earlier
  x.removeEventListener("mousemove", myFunction);
} else if (x.detachEvent) {                    // For IE 8 and earlier versions
  x.detachEvent("onmousemove", myFunction);
}
