Results of Chrome ( Followed spec1 and spec2)

button.click() - event not dispatched

button.dispatchEvent(new Event('click')); - event is dispatched

 

Results of Internet Explorer

button.click() - event not dispatched

button.dispatchEvent(new Event('click')); - event not dispatched

 

Results of Firefox

button.click() - event not dispatched

button.dispatchEvent(new Event('click')); - event not dispatched

 

 

Is there any specific reason to prevent click events that are queued on the
user interaction task source only?

What should be the behavior of other events like button.dispatchEvent(new
Event('click'))?

>From the results we can see IE and Firefox are not dispatching any click
event generated to disabled elements.

Please let me know the correct behavior.

 

 

Sample html code used to test is

 

<!DOCTYPE HTML>

<button disabled>Click me!</button>

<div id="log"></div>

<script>

function debug(msg, color) {

  var span = document.createElement("span");

  log.appendChild(span);

  span.innerHTML = msg + '<br />';

  if (color)

    span.style.color = color;

}

button = document.querySelector('button');

log = document.getElementById('log');

wasClicked = false;

button.addEventListener('click', function(e) {

 

  wasClicked = true;

  alert('click dispatched');

});

 

button.click();

if (wasClicked)

  debug('Receieved click event on button.click()\n', 'red');

else

  debug('No click event on button.click()\n', 'green');

wasClicked = false;

button.dispatchEvent(new Event('click'));

if (wasClicked)

  debug('Receieved click event on button.dispatchEvent()\n', 'red');

else

  debug('No click event on button.dispatchEvent()\n', 'green');

</script>
