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.

TypeScript

function initMap(): void {
  const directionsRenderer = new google.maps.DirectionsRenderer();
  const directionsService = new google.maps.DirectionsService();
  const map = new google.maps.Map(
    document.getElementById("map") as HTMLElement,
    {
      zoom: 7,
      center: { lat: 41.85, lng: -87.65 },
    }
  );
  directionsRenderer.setMap(map);
  directionsRenderer.setPanel(
    document.getElementById("right-panel") as HTMLElement
  );

  const control = document.getElementById("floating-panel") as HTMLElement;
  control.style.display = "block";
  map.controls[google.maps.ControlPosition.TOP_CENTER].push(control);

  const onChangeHandler = function () {
    calculateAndDisplayRoute(directionsService, directionsRenderer);
  };
  (document.getElementById("start") as HTMLElement).addEventListener(
    "change",
    onChangeHandler
  );
  (document.getElementById("end") as HTMLElement).addEventListener(
    "change",
    onChangeHandler
  );
}

function calculateAndDisplayRoute(
  directionsService: google.maps.DirectionsService,
  directionsRenderer: google.maps.DirectionsRenderer
) {
  const start = (document.getElementById("start") as HTMLInputElement).value;
  const end = (document.getElementById("end") as HTMLInputElement).value;
  directionsService.route(
    {
      origin: start,
      destination: end,
      travelMode: google.maps.TravelMode.DRIVING,
    },
    (response, status) => {
      if (status === "OK") {
        directionsRenderer.setDirections(response);
      } else {
        window.alert("Directions request failed due to " + status);
      }
    }
  );
}

JavaScript

function initMap() {
  const directionsRenderer = new google.maps.DirectionsRenderer();
  const directionsService = new google.maps.DirectionsService();
  const map = new google.maps.Map(document.getElementById("map"), {
    zoom: 7,
    center: { lat: 41.85, lng: -87.65 },
  });
  directionsRenderer.setMap(map);
  directionsRenderer.setPanel(document.getElementById("right-panel"));
  const control = document.getElementById("floating-panel");
  control.style.display = "block";
  map.controls[google.maps.ControlPosition.TOP_CENTER].push(control);

  const onChangeHandler = function () {
    calculateAndDisplayRoute(directionsService, directionsRenderer);
  };
  document.getElementById("start").addEventListener("change", onChangeHandler);
  document.getElementById("end").addEventListener("change", onChangeHandler);
}

function calculateAndDisplayRoute(directionsService, directionsRenderer) {
  const start = document.getElementById("start").value;
  const end = document.getElementById("end").value;
  directionsService.route(
    {
      origin: start,
      destination: end,
      travelMode: google.maps.TravelMode.DRIVING,
    },
    (response, status) => {
      if (status === "OK") {
        directionsRenderer.setDirections(response);
      } else {
        window.alert("Directions request failed due to " + status);
      }
    }
  );
}
