JavaScript

// This sample uses the Autocomplete widget to help the user select a

// place, and then it populates the form fields with those details.
// This sample requires the Places library. Include the libraries=places
// parameter when you first load the API. For example:
// <script
// src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places">
