…and triggering them
Recently I had an issue attempting to dispatch an event to a DOM element in a unit test. The particular element was a radio button and the way I would normally create an event:
var event = new Event('click',{'bubbles':true, 'cancelable':false})
object.dispatchEvent(event)just didn’t work, this led to some digging about, looking through various documentation .. you know the score.
In the end I had to resort to a much older method of using object.click()
object.click()
new MouseEvent('click', {bubbles:true});
