添加自定义标记到谷歌街景

Adding a custom marker to google street view

本文关键字：谷歌街 自定义 添加      更新时间：2023-09-26

请帮我添加一个标记到谷歌街景，但当我把它没有工作，我得到一个未捕获的ReferenceError: map未定义

这里是标记变量

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'
});

这是自定义的谷歌街景

<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>

  1. 要在街景视图上看到标记，必须将其添加到全景图中。Uncaught ReferenceError: map is not defined告诉你，在你的代码中没有定义map变量，它需要是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'
});

  2. 一旦我这样做，你的标记太远了，看不到。如果我将pano位置移近(并指向标记)，我就能看到它。

    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
    });
}

  panorama.setPov({

  });
  // Set up the map
  var myOptions = {
    zoom: 15,
    center: cafe
  };
  var map = new google.maps.Map(document.getElementById('map_canvas'),
    myOptions);
  var cafeMarkerMap = new google.maps.Marker({

      anchor: new google.maps.Point(3.5, 3.5)
    },
    title: 'Pano'
  });
  document.getElementById('info').innerHTML = google.maps.geometry.spherical.computeDistanceBetween(panorama.getPosition(), cafe).toFixed(2) + " meters";
}
google.maps.event.addDomListener(window, 'load', initialize);
