Page Summary
-
This sample demonstrates how to send a geocoding request for "Toledo" and receive a US-based result using the Google Maps JavaScript API.
-
The returned geocoding result can vary depending on the specified map region.
-
Sample code is provided in both TypeScript and JavaScript, along with HTML and CSS for displaying the results on a map.
-
Users can try the sample using JSFiddle or Google Cloud Shell, or clone the repository and run it locally with Node.js.
This demonstrates sending a geocoding request for "Toledo" and receiving a result in the US. The result returned depends on the region of the map. See also the demo for the ES region .
