Can multiple event listeners/handlers be added to the same element using javascript?

Question

I have:

if (window.addEventListener) {
  window.addEventListener(\'load\',videoPlayer,false);
}
else if (window.attachEvent) { 
  window.attachEvent(\'onload

/**
 * multipleEventsListeners.js
 * Add the capability to attach multiple events to an element, just like jQuery does
 * https://gist.github.com/juanbrujo/a1f77db1e6f7cb17b42b
 */

multipleEventsListeners(events, func, elem) {
  elem = elem || document;
  var event = events.split(' ');
  for (var i = 0; i < event.length; i++) {
    elem.addEventListener(event[i], func, false);
  }
}

/*
Use: 
var input = document.querySelector('input');
multipleEventsListeners(input, 'keyup change', function(e){
  console.log = this.value;
});
*/
