Get element from which onclick function is called

Question

I have a button with a onclick attribute which is pointing to the function test().

Button 1
<         


        

Answer 1

I came across an other extremely simple way to do it in Vanilla JS so I post it here for reference:

function whoami () {
  var caller = event.target;
  alert("I'm " + caller.textContent);
}

Button 1
Button 2
Button 3

I'm not sure about the browser support for it but it works at least on Safari, Firefox and Blink based browsers.
