POI Click Events
Page Summary
This example showcases how to use click event listeners on Points of Interest (POIs) on a Google Map.
When a POI icon is clicked, the code calculates and displays a route from a predefined origin to the clicked POI using the Directions Service.
It also retrieves and displays detailed information about the clicked POI, such as name, address, and place ID, in an info window.
The example prevents the default info window from showing and uses
event.stop()to manage click behavior.
This example demonstrates the use of click event listeners on POIs (points ofinterest). It listens for theclick event on a POI icon and thenuses theplaceId from the event data with adirectionsService.route request to calculate and display a route tothe clicked place. It also uses theplaceId to get more details ofthe place.
