.target javascript code example

Example 1: 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.

Example 2: 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 3: javascript .target

// Make a list
const ul = document.createElement('ul');
document.body.appendChild(ul);

const li1 = document.createElement('li');
const li2 = document.createElement('li');
ul.appendChild(li1);
ul.appendChild(li2);

function hide(evt) {
  // e.target refers to the clicked <li> element
  // This is different than e.currentTarget, which would refer to the parent <ul> in this context
  evt.target.style.visibility = 'hidden';
}

// Attach the listener to the list
// It will fire when each <li> is clicked
ul.addEventListener('click', hide, false);

Example 4: event.target javascript

const theTarget = someEvent.target;
