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

Quick solution:

var myElement = document.querySelector('#my-element');

myElement.addEventListener('resize', function() {
    console.log('resize event occurred.');
});

or:

<div id="my-element" resize="handleResize()">
  <!-- div body here... -->
</div>

or:

var myElement = document.querySelector('#my-element');

myElement.onresize = function() {
    console.log('onresize event occurred.');
};

 

Practical examples

There are three common ways how to use resize event:

  • with event listener,
  • with element¬†attribute,
  • with element property.

1. Event listener based example

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

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
  <body>
    <div>
      Window resized: <span id="my-span">0</span> times.
    </div>
    <script>
      var x = 0;
      window.addEventListener('resize', handleResize);
      function handleResize(){
        document.querySelector("#my-span").innerHTML = x += 1;
      }
    </script>
  </body>
</html>

2. Attribute based example

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

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
  <body onresize="handleResize()">
    <div>
      Window resized: <span id="my-span">0</span> times.
    </div>
    <script>
      var x = 0;
      function handleResize(){
        document.querySelector("#my-span").innerHTML = x += 1;
      }
    </script>
  </body>
</html>

3. Property based example

In this section, we want to show how to use resize event on window element via property.

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
  <body>
    <div>
      Window resized: <span id="my-span">0</span> times.
    </div>
    <script>
      var x = 0;
      window.onresize = function handleResize(){
        document.querySelector("#my-span").innerHTML = x += 1;
      }
    </script>
  </body>
</html>
