中心谷歌 Map 上的 Map ID没有指定lat和long？

如何在没有在 Map 对象中明确设置lat和lng的情况下，基于placeID将谷歌 Map 居中？

我见过的所有例子都有一个值集，例如

var pyrmont = new google.maps.LatLng(-33.8665433,151.1956316);

表单：developers.google.com

当然你可以在一个基于ID的地方获取详细信息，然后使用lat和lng将 Map 居中？

function initializeGoogleMaps() {
  jQuery('.site-content').prepend('<div id=\"map-container\"><div id=\"map-canvas\"></div></div>');

  var request = {
    placeId: 'ChIJzXBGLkQFdkgRoyT2MIxgWGw'
  };

  function callback(place, status) {
    if (status == google.maps.places.PlacesServiceStatus.OK) {
      var marker = new google.maps.Marker({
        map: map,
        position: place.geometry.location
      });
    }
  }

  var map = new google.maps.Map(document.getElementById('map-canvas'), {
    center: {
      lat: 51.509526,
      lng: -0.156314
    },
    zoom: 15
  });

  service = new google.maps.places.PlacesService(map);
  service.getDetails(request, callback);
}

    您可以使用places服务返回的值（或标记的位置）设置 Map 的中心：

    proof of concept fiddle

    function callback(place, status) {
    if (status == google.maps.places.PlacesServiceStatus.OK) {
      var marker = new google.maps.Marker({
        map: map,
        position: place.geometry.location
      });
      map.setCenter(marker.getPosition());
    }
  }

  var map = new google.maps.Map(document.getElementById('map-canvas'), {
    zoom: 15
  });

    code snippet:

    function initializeGoogleMaps() {
  var request = {
    placeId: 'ChIJzXBGLkQFdkgRoyT2MIxgWGw'
  };

  function callback(place, status) {
    if (status == google.maps.places.PlacesServiceStatus.OK) {
      var marker = new google.maps.Marker({
        map: map,
        position: place.geometry.location
      });
      map.setCenter(marker.getPosition());
    }
  }

  var map = new google.maps.Map(document.getElementById('map-canvas'), {
    zoom: 15
  });

  service = new google.maps.places.PlacesService(map);
  service.getDetails(request, callback);
}
google.maps.event.addDomListener(window, 'load', initializeGoogleMaps);

    html,
body,
#map-canvas {
  height: 100%;
  width: 100%;
  margin: 0px;
  padding: 0px
}

    <script src="https://maps.googleapis.com/maps/api/js?libraries=places"></script>
<div id="map-canvas"></div>
