click

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

O evento click event é disparado quando o botão de um dispositivo apontador (normalmente o botão de um mouse) é pressionado e solto logo em seguida em um mesmo elemento.

Propriedades

Property Type Description
target Somente leitura EventTarget O alvo do evento (o mais alto na arvore de DOM).
type Somente leitura DOMString Tipo do evento.
bubbles Somente leitura Boolean Se o evento "bubbles" naturalmente ou não.
cancelable Somente leitura Boolean Se o evento é cancelável ou não
view Somente leitura WindowProxy document.defaultView (window do documento)
detail Somente leitura long (float) Um contador de cliques consecutivos que ocorrem em um curto espaço de tempo, incrementado em 1.
currentTarget Somente leitura EventTarget O node que contem o eventListener.
relatedTarget Somente leitura EventTarget Para eventos mouseover, mouseout, mouseenter e mouseleave: o alvo do evento complementar (o mouseleave no caso de um evento mouseenter ). null , se falso.
screenX Somente leitura long A coordenada X do ponteiro do mouse na tela.
screenY Somente leitura long A coordenada Y do ponteiro do mouse na tela.
clientX Somente leitura long A coordenada X do ponteiro do mouse no DOM atual.
clientY Somente leitura long A coordenada Y do ponteiro do mouse no DOM atual.
button Somente leitura unsigned short The button number that was pressed when the mouse event was fired: Left button=0, middle button=1 (if present), right button=2. For mice configured for left handed use in which the button actions are reversed the values are instead read from right to left.
buttons Somente leitura unsigned short The buttons being pressed when the mouse event was fired: Left button=1, Right button=2, Middle (wheel) button=4, 4th button (typically, "Browser Back" button)=8, 5th button (typically, "Browser Forward" button)=16. If two or more buttons are pressed, returns the logical sum of the values. E.g., if Left button and Right button are pressed, returns 3 (=1 | 2). More info.
mozPressure Somente leitura float The amount of pressure applied to a touch or tabdevice when generating the event; this value ranges between 0.0 (minimum pressure) and 1.0 (maximum pressure).
ctrlKey Somente leitura boolean true if the control key was down when the event was fired. false otherwise.
shiftKey Somente leitura boolean true if the shift key was down when the event was fired. false otherwise.
altKey Somente leitura boolean true if the alt key was down when the event was fired. false otherwise.
metaKey Somente leitura boolean true if the meta key was down when the event was fired. false otherwise.

Exemplo

js
<div id="test"></div>

<script>
  document.getElementById("test").addEventListener("click", function( event ) {
    // mostra o contador de cliques dentro da div clicada
    event.target.innerHTML = "Total de cliques: " + event.detail;
  }, false);
</script>

Compatibilidade com navegadores

Internet Explorer

O Internet Explorer 8 e 9 apresentam um bug onde o elemento com a propriedade background-color é definida como transparent that are overlaid on top of other element(s) won't receive click events. Todos os eventos click serão disparados no elemento underlying instead. Veja uma demonstração neste exemplo.

Safari Mobile

BCD tables only load in the browser

Safari Mobile 7.0+ (and likely earlier versions too) suffers from a bug where click events aren't fired on elements that aren't typically interactive (e.g. <div>) and which also don't have event listeners directly attached to the elements themselves (i.e. event delegation is being used). See this live example for a demonstration. See also Safari's docs on making elements clickable and the definition of "clickable element".

Known workarounds for this bug:

  • Set cursor: pointer; on the element or any of its ancestors.
  • Add a dummy onclick="void(0)" attribute to the element or any of its ancestors up to but not including <body>.
  • Use a typically interactive element (e.g. <a>) instead of one that isn't typically interactive (e.g. <div>).
  • Stop using click event delegation.

Safari Mobile considers the following elements to be typically interactive (and thus they aren't affected by this bug):

  • <a> (but it must have an href)
  • <area> (but it must have an href)
  • <button>
  • <img>
  • <input>
  • <label> (but it must be associated with a form control)
  • <textarea>
  • This list is incomplete; you can help MDN by doing further testing/research and expanding it.
