使用數組將多個自定義標記添加到Google地圖

Question

我目前正在為我的網站實施google map，偶然發現了一個很棒的教程，這幾乎使我進入了承諾的領域。 但是，我還想添加另一項功能。 在數組內部，我想在地圖上顯示三個不同的自定義標記之一。 有人有什么想法嗎？

 var locations = [ ['Bondi Beach', -33.890542, 151.274856, 4], ['Coogee Beach', -33.923036, 151.259052, 5], ['Cronulla Beach', -34.028249, 151.157507, 3], ['Manly Beach', -33.80010128657071, 151.28747820854187, 2], ['Maroubra Beach', -33.950198, 151.259302, 1] ]; var map = new google.maps.Map(document.getElementById('map'), { zoom: 10, center: new google.maps.LatLng(-33.92, 151.25), mapTypeId: google.maps.MapTypeId.ROADMAP }); var infowindow = new google.maps.InfoWindow(); var marker, i; for (i = 0; i < locations.length; i++) { marker = new google.maps.Marker({ position: new google.maps.LatLng(locations[i][1], locations[i][2]), map: map }); google.maps.event.addListener(marker, 'click', (function (marker, i) { return function () { infowindow.setContent(locations[i][0]); infowindow.open(map, marker); } })(marker, i)); } 

 <div id="map" style="width: 500px; height: 400px;"></div> 

Answer 1

最簡單的解決方案是，將標記所需圖標的URL添加到數組中：

var locations = [
    ['Bondi Beach', -33.890542, 151.274856, 4, "http://maps.google.com/mapfiles/ms/micons/blue.png"],
    ['Coogee Beach', -33.923036, 151.259052, 5, "http://maps.google.com/mapfiles/ms/micons/green.png"],
    ['Cronulla Beach', -34.028249, 151.157507, 3, "http://maps.google.com/mapfiles/ms/micons/yellow.png"],
    ['Manly Beach', -33.80010128657071, 151.28747820854187, 2, "http://maps.google.com/mapfiles/ms/micons/blue.png"],
    ['Maroubra Beach', -33.950198, 151.259302, 1, "http://maps.google.com/mapfiles/ms/micons/blue.png"]
];

然后在標記構造函數中使用它：

marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i][1], locations[i][2]),
    icon: locations[i][4],
    map: map
});

代碼段：

 var locations = [ ['Bondi Beach', -33.890542, 151.274856, 4, "http://maps.google.com/mapfiles/ms/micons/blue.png"], ['Coogee Beach', -33.923036, 151.259052, 5, "http://maps.google.com/mapfiles/ms/micons/green.png"], ['Cronulla Beach', -34.028249, 151.157507, 3, "http://maps.google.com/mapfiles/ms/micons/yellow.png"], ['Manly Beach', -33.80010128657071, 151.28747820854187, 2, "http://maps.google.com/mapfiles/ms/micons/blue.png"], ['Maroubra Beach', -33.950198, 151.259302, 1, "http://maps.google.com/mapfiles/ms/micons/blue.png"] ]; var map = new google.maps.Map(document.getElementById('map'), { zoom: 10, center: new google.maps.LatLng(-33.92, 151.25), mapTypeId: google.maps.MapTypeId.ROADMAP }); var infowindow = new google.maps.InfoWindow(); var marker, i; for (i = 0; i < locations.length; i++) { marker = new google.maps.Marker({ position: new google.maps.LatLng(locations[i][1], locations[i][2]), icon: locations[i][4], title: locations[i][0], map: map }); google.maps.event.addListener(marker, 'click', (function(marker, i) { return function() { infowindow.setContent(locations[i][0]); infowindow.open(map, marker); } })(marker, i)); } 

 html, body, #map { width: 100%; height: 100%; } 

 <script src="http://maps.google.com/maps/api/js"></script> <div id="map"></div> 

Answer 2

您沒有告訴我們何時要顯示自定義標記，但是要顯示自定義標記，您只需定義要顯示的圖像，並將傳遞給標記對象的圖像作為圖標：yourMarker。

如果要添加條件語句以顯示給定特定條件的特定標記，則可以使用if / else語句進行操作。

我將數組數組轉換為對象數組，並添加了用戶屬性。 然后，我調整了代碼以使用對象而不是數組索引。

var locations = [
{
   name: 'Bondi Beach',
   lat: -33.890542,
   lon: 151.274856,
   user: 1
}, /*[......]*/
{
   name: 'Maroubra Beach',
   lat: -33.950198,
   lon: 151.259302,
   user: 3
}
];

if (locations[i].user === 1){
   var icon = blueStar
} else if (locations[i].user === 2) { 
   var icon = goldStar
}
else if (locations[i].user === 3) { 
   var icon = redStar
}

marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i].lat, locations[i].lon),
    icon: icon,
    map: map
});
