Add Event Listener to Collection of HTML Elements

Question

I know that getElementsByTagName and getElementsByClassName need an index identifier in order for the objects to be bound to an event listener.

Answer 1

var i=0, inputElem = document.getElementsByTagName('input'), len = inputElem.length;    
while(i < len){
  inputElem[i].addEventListener('click', function(){
      alert(this.value);
  }, false);
 i++;
}
