In this article, we will see how to run the code on change event using jQuery. The change event is used to trigger when the user changes the value of the element.

Syntax:

$(selector).change(function)

In the below example, we are creating a textarea element that contains GeeksforGeeks text. When the user changes the textarea content and remove the cursor from textarea, the change event is triggered and the styles added on the textarea element.

 

Example:

HTML




<!DOCTYPE html>
<html>
  
<head>
    <title>

    </title>
  
    <script src=
    </script>
  
    <script>
        $(document).ready(function() {
            $("textarea").change(function() {
                $("textarea").css({
                    background: "green",
                    color: "white"
                });
            });
        });
    </script>
</head>
  
<body>
    <center>
        <h1 style="color: green;">
            GeeksforGeeks
        </h1>
  
        <h3>
