`aler` <-- Do you actually have the typo – epascarello Jul 17 '20 at 19:31

getElementsByClassName returns an HTML collection – epascarello Jul 17 '20 at 19:31
@epascarello ohh change aler to console.log but not work – koki Jul 17 '20 at 19:32

document.getElementsByClassName returns an array of HTML elements, you may need to reference which element in array you want to add the onclick event. e.g. p[0].onclick = showAlert(); – Ank Jul 17 '20 at 19:32
