How to set alert message on button click in jQuery ?

  • Last Updated : 28 Jul, 2021

In this article, we will learn how to create an alert message in jQuery when a button gets clicked. For this, we will use the jQuery click() method.

jQuery CDN Link: We have linked the jQuery in our file using the CDN link. 

<script src=”https://code.jquery.com/jquery-3.6.0.min.js” integrity=”sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4=” crossorigin=”anonymous”;>
</script>

Example: Create a new HTML file and add the following code to it. In this method, we have set an alert and linked it to a button so that when that button gets clicked then the alert message will be popping out.

HTML




<!DOCTYPE html>
<html lang="en">
  
<head>
    <script src=
        integrity=
"sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4=" 
        crossorigin="anonymous">
    </script>
</head>
  
<body>
    <button id="btn">Click me!</button>
  
    <script>
        $(document).ready(function () {
            $("#btn").click(function () {
                alert("This is an alert message!");
            });
        });
    </script>
</body>
  
</html>

Output:

Alert msg using click method
