e.target in js code example

Example 1: event target javascript

Using the event.target property together with the element.tagName property to find out which element triggered a specified event:

<body onclick="myFunction(event)">
<p>Click on any elements in this document to find out which element triggered the onclick event.</p>
<h1>This is a heading</h1>
<button>This is a button</button>
<p id="demo"></p>

<script>
function myFunction(event) { 
  var x = event.target;
  document.getElementById("demo").innerHTML = "Triggered by a " + x.tagName + " element";
}
</script>

Example 2: what is e.target in javascript

The target property gets the element on which the event originally occurred, 
opposed to the currentTarget property, which always refers to the element 
whose event listener triggered the event.
