Javascript DOM onblur Event via addEventListener() method

Introduction

In JavaScript, using the addEventListener() method: 

object.addEventListener("blur",
       myScript);

This example uses the addEventListener() method to attach a "blur" event to an input element.

Write something in the input field, and then click outside the field to lose focus (blur).
