Detect Close Windows Event By Jquery

Have you ever wanted to add a feature to your website that detects when a user is about to close a window or a tab? If so, jQuery can help you achieve this seamlessly. In this article, we'll walk you through how to use jQuery to detect the close window event on your website.

When a user tries to close a window or a tab, it can be helpful to trigger a specific action, such as displaying a message to confirm if they want to leave the page or executing a function to save their progress. With jQuery, you can easily detect the close window event and handle it gracefully.

To get started, make sure you have jQuery included in your project. You can either download jQuery and include it in your HTML file or use a CDN link to include it. Here's an example of how you can include jQuery using a CDN link:

Once you have jQuery set up, you can start detecting the close window event. You can use the `beforeunload` event in jQuery to perform an action before the browser unloads the current page. Here's a simple example of how you can detect the close window event using jQuery:

$(window).on('beforeunload', function() {
  return 'Are you sure you want to leave?';
});

In this example, we're attaching a `beforeunload` event handler to the `window` object. When the user tries to close the window or tab, a confirmation message `'Are you sure you want to leave?'` will be displayed to the user. The user can then choose to stay on the page or proceed with closing the window.

You can also perform custom actions when the close window event is triggered. For example, you can make an AJAX call to save the user's data before they leave the page. Here's an example of how you can achieve this:

$(window).on('beforeunload', function() {
  $.ajax({
    url: 'saveUserData.php',
    method: 'POST',
    data: { userData: 'example data' },
    async: false
  });
});

In this example, we're making an AJAX call to a server-side script `saveUserData.php` to save the user's data before the window is closed. By setting `async: false`, we ensure that the AJAX call completes before the window is unloaded.

Detecting the close window event using jQuery can enhance the user experience on your website by providing an intuitive way to handle page exits. Whether you want to display a confirmation message or save user data before they leave, jQuery offers a simple and effective solution.
