Simple Click Events
AI-generated Key Takeaways
This example showcases the implementation of event listeners in Google Maps using JavaScript or TypeScript.
Clicking the marker on the map triggers a zoom-in and centers the map on the marker's location.
The map automatically pans back to the marker's position 3 seconds after the center of the map is changed.
Code samples in JavaScript, TypeScript, HTML, and CSS are provided, alongside links to documentation and live demos.
This example demonstrates the use of event listeners. It
- listens for the
clickevent on a marker to zoom the map when the marker is clicked. - listens for the
center_changedevent to pan the map back to the marker after 3 seconds.

CSS
/* * Always set the map height explicitly to define the size of the div element * that contains the map. */#map{height:100%;}/* * Optional: Makes the sample page fill the window. */html,body{height:100%;margin:0;padding:0;}
