Place Autocomplete and Directions | Maps JavaScript API

Stay organized with collections Save and categorize content based on your preferences.

This sample allows a user to specify source and destination locations, and then it uses the DirectionsService to calculate the route, and the DirectionsRenderer to display the route.

For more information, see Autocomplete for Addresses and Search Terms, and the Directions Service.

// This example requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
// <script
