    $.ajax({
         type: "POST",
         url: url,
         data: form.serialize(), // serializes form input

    type: "POST", // data type (can be get, post, put, delete)
    data : formData, // data in json format

            url         : 'process.php', // the url where we want to POST
            data        : formData, // our data object

                        encode          : true
        })
            // using the done promise callback
            .done(function(data) {

                // log data to the console so we can see
                console.log(data);

                // here we will handle errors and validation messages
            });

        // stop the form from submitting the normal way and refreshing the page
        event.preventDefault();
    });
