Place Autocomplete Hotel Search


This example creates a map with a search box that finds all of the hotels in a specified place within a given country. The map then displays markers for all of the hotels returned, with on-click details for each hotel.

// This example uses the autocomplete feature of the Google Places API.
// It allows the user to find all hotels in a given place, within a given
// country. It then displays markers for all the hotels returned,
// with on-click details for each hotel.

// This example 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">
