<h2>jQuery AJAX Event - ajaxSend Method()</h2>
		<p>This example uses <kbd>ajaxSend</kbd> to notify just before the AJAX request is sent to the server.</p>

<form id="userForm">
			<label>Name: <input type="text" name="name" /></label><br><br>
			<label>Email: <input type="email" name="email" /></label><br><br>
			<label>City: <input type="text" name="city" /></label><br><br>
			<button type="submit" id="submitForm">Submit</button>
		</form>

<div id="loader"><span class="spinner"></span>Submitting data, please wait...</div>
		<div id="sendBox">AJAX request is about to be sent...</div>
		<div id="response">Server response will appear here.</div>

// Hide loader when all AJAX calls complete
				$(document).ajaxStop(function () {
					$('#loader').hide();
				});

// Show message just before AJAX request is sent
				$(document).ajaxSend(function () {
					$('#sendBox').show().delay(2000).fadeOut();
				});

// Form submission
				$('#userForm').on('submit', function (e) {
					e.preventDefault();
					const formData = $(this).serialize();
					$.ajax({
						url: 'jquery-serialize.php',
						type: 'POST',
						data: formData,
						success: function (response) {
							$('#response').html(response);
						},
						error: function () {
							$('#response').html('Error submitting form.');
						}
					});
				});
			});
