Displaying text directions with setPanel()

This example demonstrates the use of the DirectionsRenderer object to display a directions panel.

Select a new start and end point to see the directions render on the map and inside the directions panel to the right of the map.

Read the documentation or view this example fullscreen.

function initMap() {
  var directionsDisplay = new google.maps.DirectionsRenderer;
  var directionsService = new google.maps.DirectionsService;
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 7,
    center: {lat: 41.85, lng: -87.65}
  });
  directionsDisplay.setMap(map);
  directionsDisplay.setPanel(document.getElementById('right-panel'));

  var control = document.getElementById('floating-panel');
  control.style.display = 'block';
  map.controls[google.maps.ControlPosition.TOP_CENTER].push(control);

  var onChangeHandler = function() {
    calculateAndDisplayRoute(directionsService, directionsDisplay);
  };
  document.getElementById('start').addEventListener('change', onChangeHandler);
  document.getElementById('end').addEventListener('change', onChangeHandler);
}

function calculateAndDisplayRoute(directionsService, directionsDisplay) {
  var start = document.getElementById('start').value;
  var end = document.getElementById('end').value;
  directionsService.route({
    origin: start,
    destination: end,
