This example displays a map, alongside a window that shows the Street View at
the current marker's location on the map. The user can click the map to place a
new marker and move the Street View location.

[documentation](https://developers.google.com/maps/documentation/javascript/streetview.md.txt#StreetViewService).

### TypeScript

```typescript
/*
 * Click the map to set a new location for the Street View camera.
 */

let map: google.maps.Map;

let panorama: google.maps.StreetViewPanorama;

function initMap(): void {
  const berkeley = { lat: 37.869085, lng: -122.254775 };
  const sv = new google.maps.StreetViewService();

  panorama = new google.maps.StreetViewPanorama(
    document.getElementById("pano") as HTMLElement
  );

  // Set up the map.
  map = new google.maps.Map(document.getElementById("map") as HTMLElement, {
    center: berkeley,
    zoom: 16,
    streetViewControl: false,
  });

  // Set the initial Street View camera to the center of the map
  sv.getPanorama({ location: berkeley, radius: 50 }).then(processSVData);

  // Look for a nearby Street View panorama when the map is clicked.
  // getPanorama will return the nearest pano when the given
  // radius is 50 meters or less.
  map.addListener("click", (event) => {
    sv.getPanorama({ location: event.latLng, radius: 50 })
      .then(processSVData)
      .catch((e) =>
        console.error("Street View data not found for this location.")
      );
  });
}

function processSVData({ data }: google.maps.StreetViewResponse) {
  const location = data.location!;

  const marker = new google.maps.Marker({
    position: location.latLng,
    map,
    title: location.description,
  });

  panorama.setPano(location.pano as string);
  panorama.setPov({
    heading: 270,
    pitch: 0,
  });
  panorama.setVisible(true);

  marker.addListener("click", () => {
    const markerPanoID = location.pano;

    // Set the Pano to use the passed panoID.
    panorama.setPano(markerPanoID as string);
    panorama.setPov({
      heading: 270,
      pitch: 0,
    });
    panorama.setVisible(true);
  });
}

declare global {
  interface Window {
    initMap: () => void;
  }
}
window.initMap = initMap;
```

### JavaScript

```javascript
/*
 * Click the map to set a new location for the Street View camera.
 */
let map;
let panorama;

function initMap() {
  const berkeley = { lat: 37.869085, lng: -122.254775 };
  const sv = new google.maps.StreetViewService();

  panorama = new google.maps.StreetViewPanorama(
    document.getElementById("pano"),
  );
  // Set up the map.
  map = new google.maps.Map(document.getElementById("map"), {
    center: berkeley,
    zoom: 16,
    streetViewControl: false,
  });
  // Set the initial Street View camera to the center of the map
  sv.getPanorama({ location: berkeley, radius: 50 }).then(processSVData);
  // Look for a nearby Street View panorama when the map is clicked.
  // getPanorama will return the nearest pano when the given
  // radius is 50 meters or less.
  map.addListener("click", (event) => {
    sv.getPanorama({ location: event.latLng, radius: 50 })
      .then(processSVData)
      .catch((e) =>
        console.error("Street View data not found for this location."),
      );
  });
}

function processSVData({ data }) {
  const location = data.location;
  const marker = new google.maps.Marker({
    position: location.latLng,
    map,
    title: location.description,
  });

  panorama.setPano(location.pano);
  panorama.setPov({
    heading: 270,
    pitch: 0,
  });
  panorama.setVisible(true);
  marker.addListener("click", () => {
    const markerPanoID = location.pano;

    // Set the Pano to use the passed panoID.
    panorama.setPano(markerPanoID);
    panorama.setPov({
      heading: 270,
      pitch: 0,
    });
    panorama.setVisible(true);
  });
}

window.initMap = initMap;
```

### CSS

```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;
}
```

### HTML

```html
