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

Quick solution:

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

or:

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

or:

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

Practical examples

Edit

There are three common ways how to use onselect event:

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

1. Event listener based example

  <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>
