Question

请帮我添加一个标记到谷歌街景，但当我把它放在任何无效的工作，我得到一个未捕获的ReferenceError：未定义map

继承标记变量

var cafe = new google.maps.LatLng(34.935196, -107.539546);

下面是设置标记的代码

var cafeMarker = new google.maps.Marker({
  position: cafe,
  map: map,
  icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_icon&chld=cafe|FFFF00',
  title: 'Cafe'
});

继承自定义谷歌街景

<script src="https://maps.googleapis.com/maps/api/js? v=3.exp&signed_in=true"></script>
<script>


function initialize() {
   var fenway = new google.maps.LatLng(34.938447, -107.535998);

   var panoOptions = {
       position: fenway,
       addressControlOptions: {
         position: google.maps.ControlPosition.BOTTOM_CENTER
       },
       linksControl: false,
       panControl: false,
       zoomControlOptions: {
         style: google.maps.ZoomControlStyle.SMALL
       },
       enableCloseButton: false
   };

  var panorama = new google.maps.StreetViewPanorama(
  document.getElementById('map-canvas'), panoOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);

</script>

要在StreetView上查看标记，您必须将其添加到全景图中。 Uncaught ReferenceError: map is not defined告诉您代码中没有定义map变量，需要panorama。

var cafeMarker = new google.maps.Marker({
  position: cafe,
  map: panorama, // your code doesn't have a 'map' variable
  icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_icon&chld=cafe|FFFF00',
  title: 'Cafe'
});

一旦我这样做，你的标记太遥远了。如果我将全景位置移近（并将其指向标记处），我会看到它。

function initialize() {
    var fenway = new google.maps.LatLng(34.9355,-107.539254);

    var panoOptions = {
        position: fenway,
        addressControlOptions: {
            position: google.maps.ControlPosition.BOTTOM_CENTER
        },
        linksControl: false,
        panControl: false,
        zoomControlOptions: {
        style: google.maps.ZoomControlStyle.SMALL
        },
        enableCloseButton: false
    };

    var panorama = new google.maps.StreetViewPanorama(
    document.getElementById('map-canvas'), panoOptions);

    var cafe = new google.maps.LatLng(34.935196, -107.539546);

    var cafeMarker = new google.maps.Marker({
        position: cafe,
        map: panorama,
        icon: 'http://chart.apis.google.com/chart?chst=d_map_pin_icon&chld=cafe|FFFF00',
        title: 'Cafe'
    });
       var heading = google.maps.geometry.spherical.computeHeading(panorama.getPosition(),cafe);

    panorama.setPov({
      heading: heading,
      pitch: 0,
      zoom: 1
    });

}
