Jquery Ajax Submit Form

jQuery AJAX submit form

As a tech professional working with JavaScript, you may often come across the need to submit a form using AJAX. AJAX allows you to send form data to a server without refreshing the entire page, providing a smoother user experience. In this blog post, we will explore how to achieve this using jQuery.

Using jQuery’s $.ajax() method

jQuery provides a convenient method called $.ajax() which allows you to make AJAX requests. To submit a form using AJAX, you can listen for the form’s submit event and prevent the default form submission behavior. Then, you can use the $.ajax() method to send the form data to the server.
Here’s an example:

$(document).ready(function() {
    $('form').submit(function(event) {
        event.preventDefault(); // Prevent default form submission

        var form = $(this);
        var url = form.attr('action');
        var method = form.attr('method');
        var data = form.serialize(); // Serialize form data

        $.ajax({
            url: url,
            method: method,
            data: data,
            success: function(response) {
                // Handle successful form submission
            },
            error: function(xhr, status, error) {
                // Handle form submission error
            }
        });
    });
});

In the above code snippet, we listen for the submit event of any form on the page. When the form is submitted, we prevent the default form submission behavior using event.preventDefault(). Then, we extract the form’s action URL, method, and serialized form data using form.attr() and form.serialize() respectively.
Finally, we make an AJAX request using $.ajax(), specifying the URL, method, data, and success/error handlers. You can customize the success and error handlers to perform actions based on the server’s response.

Alternative solution using jQuery’s $.post() method

If you only need to perform a POST request to submit the form data, you can use jQuery’s $.post() method instead of $.ajax(). This method simplifies the code by automatically setting the HTTP method to POST.
Here’s an example:

$(document).ready(function() {
    $('form').submit(function(event) {
        event.preventDefault(); // Prevent default form submission

        var form = $(this);
        var url = form.attr('action');
        var data = form.serialize(); // Serialize form data

        $.post(url, data, function(response) {
            // Handle successful form submission
        }).fail(function(xhr, status, error) {
            // Handle form submission error
        });
    });
});

In this alternative solution, we replace the $.ajax() method with $.post(). The $.post() method takes the URL, data, and success handler as parameters. We can chain the .fail() method to handle any errors that occur during the form submission.

Conclusion

Submitting a form using AJAX in jQuery is a powerful technique that enhances the user experience by providing seamless form submissions. By utilizing the $.ajax() or $.post() methods, you can easily send form data to a server without refreshing the entire page. Remember to handle the server’s response appropriately in the success and error handlers.
