This example listens for the `click` event, gets the latitude and longitude
coordinates of the click from `google.maps.MapMouseEvent.latLng`, and displays
those coordinates in an info window.

### TypeScript

```typescript
async function init() {
    // Request needed libraries.
    const { InfoWindow } = await google.maps.importLibrary('maps');

    // Set up the map.
    const mapElement = document.querySelector('gmp-map')!;
    const innerMap = mapElement.innerMap;

    // Get the initial center of the map.
    const position = innerMap.getCenter();

    // Create the initial InfoWindow.
    let infoWindow = new InfoWindow({
        content: 'Click the map to get Lat/Lng!',
        position,
    });

    infoWindow.open(innerMap);

    // Configure the click listener.
    innerMap.addListener(
        'click',
        (mapsMouseEvent: google.maps.MapMouseEvent) => {
            // Close the current InfoWindow.
            infoWindow.close();

            // Create a new InfoWindow.
            infoWindow = new InfoWindow({
                position: mapsMouseEvent.latLng,
            });
            infoWindow.setContent(
                JSON.stringify(mapsMouseEvent.latLng!.toJSON(), null, 2)
            );
            infoWindow.open(innerMap);
        }
    );
}

void init();
```

### Try Sample

[JSFiddle.net](https://jsfiddle.net/gh/get/library/pure/googlemaps-samples/js-api-samples/tree/main/dist/samples/event-click-latlng/jsfiddle)

### Clone Sample


Git and Node.js are required to run this sample locally. Follow these [instructions](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm)
to install Node.js and NPM. You will also need a [Google Maps API key](https://developers.google.com/maps/documentation/javascript/get-api-key.md.txt).


The following commands clone the repository, install dependencies, and copy the environment file.

```javascript
  git clone https://github.com/googlemaps-samples/js-api-samples.git
  cd js-api-samples
  npm i
  cp .env.template .env
```


Once you copy the environment file, make sure to open the `.env` file and replace `<Insert your own development API key here>` with your actual API key before starting the sample.

```javascript
  cd samples/event-click-latlng
  npm start
```
