First you have to send the data to the server via javascript, for example using jQuery:

$.ajax({
	url: $('your-form-id').attr('action'),
	type: 'POST',
	dataType: 'json',
	data: $('your-form-id').serialize(),
	beforeSend: function (xhr) {
		// Set the X-CSRF-Token header if the csrf is enabled in your Cake app. 
		// I'm using here the Cookies jquery plugin
		xhr.setRequestHeader('X-CSRF-Token', Cookies.get('csrfToken'));
	},
	success: function (result, status, xhr) {
	    if (result.status == 200) {
	    	console.log('ok, you replace the form');
	    } else {
	        console.log('error, you show an error message');
	    }
	},
	complete: function () {
	    // if you need it
	}
});

Then in Cake you send back a serialized data in the controller:

publuc function yourControllerAction() {

  $this->request->allowMethod(['post', 'ajax']);

  $status = 403;
  $msg = null;
  $errors = false;

  /**
   your logic goes here
   **/

  $this->set([
      'status' => $status,
      'message' => $msg,
      'errors' => $errors,
      '_serialize' => ['status', 'message', 'errors']
  ]);
}
