How to stop event capturing in javascript?

Question

We can use event.stopPropagation() for stopping event bubbling. Can we use same method for stopping event capturing also?

If no how can we achieve it?

Answer 1

If a listener has been added to the capturing phase, rather than the bubbling phase, then you can prevent the event from capturing down to child elements with the same method: event.stopPropagation().

For example, in this code, you'll see that #inner's listener is never triggered, because #outer's listener stops the event from propagating downward:

document.querySelector('#outer').addEventListener(
  'click',
  function(event) {
    console.log('propagation stopped');
    event.stopPropagation();
  },
  true // Add listener to *capturing* phase
);

document.querySelector('#inner').addEventListener(
  'click',
  function(e) {
    console.log('inner clicked');
  }
);

<div id="outer">
  outer
  <div id="inner">
    inner
  </div>
</div>

You should pass false as the third argument to the function addEventListener(). This disables the event capturing stage.

document.body.addEventListener('click', onClickFunc, false);
