On an input[type='number'] Edge always returns `NaN` for `valueAsNumber`

Question

The following works fine in Chrome and Firefox, however in Edge it will alert NaN no matter the input

Answer 1

I don't know why Edge doesn't support valueAsNumber on type="number", but it does support it on range, week, month, and date:

document.addEventListener('click', function(e) {
  if(e.target.nodeName === 'BUTTON') {
    alert(e.target.previousElementSibling.valueAsNumber);
  }
});

          Alert number
    Alert number
     Alert number
  Alert number
