将多个位置添加到 google js 地图

Question

我正在尝试将 3 个位置添加到我嵌入在我正在开发的网站中的 Google 地图中。现在，地图正在使用单个位置图钉按预期工作。有没有办法修改js文件添加附加点？

// ==========  START GOOGLE MAP ========== //
function initialize() {
var myLatLng = new google.maps.LatLng(30.227686, -81.386146); 



var mapOptions = {
zoom: 14,
center: myLatLng,
disableDefaultUI: true,
scrollwheel: false,
navigationControl: false,
mapTypeControl: false,
scaleControl: false,
draggable: true,
mapTypeControlOptions: {
mapTypeIds: [google.maps.MapTypeId.ROADMAP, 'roadatlas']
}
};

var map = new google.maps.Map(document.getElementById('map-canvas'),  mapOptions);



var marker = new google.maps.Marker({
  position: myLatLng,
  map: map,
  icon: 'img/location-icon.png',
  title: '',
 });

 var contentString = '<div style="max-width: 300px" id="content">'+
  '<div id="bodyContent">'+
  '<h5 class="color-primary"><strong>Location 1</br> Ponte Vedra   Office</strong></h5>' +
  '<p style="font-size: 12px">103 B Solana Road </br>' +
  'Ponte Vedra, FL 32082</br>' +
  'Phone: 904-273-2717</p>'+
  '</div>'+
  '</div>';

var infowindow = new google.maps.InfoWindow({
  content: contentString
});

google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});

var styledMapOptions = {
name: 'US Road Atlas'
};

var usRoadMapType = new google.maps.StyledMapType(
  roadAtlasStyles, styledMapOptions);

map.mapTypes.set('roadatlas', usRoadMapType);
map.setMapTypeId('roadatlas');
}

google.maps.event.addDomListener(window, "load", initialize);






// ========== END GOOGLE MAP ========== //

我正在尝试在我的地图上包含这 3 个纬度/经度集： (30.227686, -81.386146) (30.650060, -81.455185) (30.056330, -81.535824)

谢谢！

Answer 1

您的代码带有原始标记和两个附加标记（第一个标记只有一个信息窗口）。

代码sn-p：

// ==========  START GOOGLE MAP ========== //
function initialize() {
  var map = new google.maps.Map(document.getElementById('map-canvas'));

  // I am trying to include these 3 latitude/longitude sets on my map: (30.227686, -81.386146) (30.650060, -81.455185) (30.056330, -81.535824)

  var marker = new google.maps.Marker({
    position: new google.maps.LatLng(30.227686, -81.386146),
    map: map,
    // icon: 'img/location-icon.png',
    title: '1',
  });
  var marker2 = new google.maps.Marker({
    position: new google.maps.LatLng(30.650060, -81.455185),
    map: map,
    // icon: 'img/location-icon.png',
    title: '2',
  });
  var marker3 = new google.maps.Marker({
    position: new google.maps.LatLng(30.056330, -81.535824),
    map: map,
    // icon: 'img/location-icon.png',
    title: '3',
  });
  
  // show all the markers on the map, replaces the mandatory zoom/center parameters in mapOptions
  var bounds = new google.maps.LatLngBounds();
  bounds.extend(marker.getPosition());
  bounds.extend(marker2.getPosition());
  bounds.extend(marker3.getPosition());
  map.fitBounds(bounds);

  var contentString = '<div style="max-width: 300px" id="content">' +
    '<div id="bodyContent">' +
    '<h5 class="color-primary"><strong>Location 1</br> Ponte Vedra   Office</strong></h5>' +
    '<p style="font-size: 12px">103 B Solana Road </br>' +
    'Ponte Vedra, FL 32082</br>' +
    'Phone: 904-273-2717</p>' +
    '</div>' +
    '</div>';

  var infowindow = new google.maps.InfoWindow({
    content: contentString
  });

  google.maps.event.addListener(marker, 'click', function() {
    infowindow.open(map, marker);
  });

  var styledMapOptions = {
    name: 'US Road Atlas'
  };

  var usRoadMapType = new google.maps.StyledMapType(
    roadAtlasStyles, styledMapOptions);

  map.mapTypes.set('roadatlas', usRoadMapType);
  map.setMapTypeId('roadatlas');
}

google.maps.event.addDomListener(window, "load", initialize);
// ========== END GOOGLE MAP ========== / /

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

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

只需添加其他 2 个标记（类似于您在上面实现 marker 对象的方式，但请确保为 position 分配不同的值）。
