In this article, we would like to show you oninput event example in JavaScript.

Quick solution:

xxxxxxxxxx
 
var myElement = document.querySelector('#my-element');
​
myElement.addEventListener('input', function() {
    console.log('oninput event occurred.');
});

or:

xxxxxxxxxx
 
<input type="text" oninput="handleInput()">

or:

xxxxxxxxxx
 
var myElement = document.querySelector('#my-element');
​
myElement.oninput = function() {
    console.log('oninput event occurred.');
};

Practical examples

Edit

There are three common ways how to use oninput event:

with event listener,
with element attribute,
with element property.

1. Event listener based example

Edit

In this section, we want to show how to use oninput event on input element via event listener mechanism.

<!doctype html>
<html>
  <body>
    <input type="text" id="my-input">
    <script>
      var myInput = document.querySelector('#my-input');
​
      myInput.addEventListener('input', function() {
        console.log('oninput event occurred.');
      });
    </script>
  </body>
</html>

Auto running

2. Attribute based example

Edit

In this section, we want to show how to use oninput event on input element via attribute.

  <body>
    <input type="text" oninput="handleInput()">
    <script>
      function handleInput(){
        console.log('oninput event occurred.');
      }
    </script>
  </body>
</html>

3. Property based example
