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

Quick solution:

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

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

or:

<input type="text" onselect="handleSelect()" value="Example text to select.">

or:

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

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

 

Practical examples

There are three common ways how to use onselect 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 onselect event on input element via event listener mechanism.

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
  <body>
    <input type="text" id="my-input" value="Select this text.">
    <script>
      var myInput = document.querySelector('#my-input');

      myInput.addEventListener('select', function() {
        console.log('onselect event occurred.');
      });
    </script>
  </body>
</html>

2. Attribute based example

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

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
  <body>
    <input type="text" onselect="handleSelect()" value="Select this text.">
    <script>
      function handleSelect(){
        console.log('onselect event occurred.');
      }
    </script>
  </body>
</html>

3. Property based example

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

// ONLINE-RUNNER:browser;

<!doctype html>
<html>
  <body>
    <input type="text" id="my-input" value="Select this text.">
    <script>
      var myInput = document.querySelector('#my-input');

      myInput.onselect = function() {
        console.log('onselect event occurred.');
      };
