Regular event

A "regular event" is a very simple mechanism to bind an event listener to an element. The event listener is executed every time the event is triggered.

To construct the event listener, the module TYPO3/CMS/Core/Event/RegularEvent must be imported. The constructor accepts the following arguments:

• eventName (string) - the event to listen on

• callback (function) - the executed event listener when the event is triggered

new RegularEvent('click', function (e) {
  console.log('Clicked element:', e.target);
}).bindTo(document.getElementById('#'));
