Google Map APIのアイコン/マーカーとしてカスタム画像を使用しています。ユーザーが地図を拡大すると、マーカー画像のサイズを変更したいと思います。ズーム付きのカスタム画像マーカーのサイズ変更 - Google Maps API v3
私はこの質問からのコードの一部を採用した:Google Maps :: Changing icon based on zoom level
は残念ながら、このスクリプトは私のリストの最後の緯度/経度マーカーを変更します。なぜ私は間違いを指摘することができますか?
var locations = [
['Aaron Baddeley (130)',-25.274398,133.775136],
['Adam Hadwin (176)',52.939916,-106.450864],
['Adam Scott (7)',-26.65,153.066667],
['Adilson da Silva (291)',-28.530554,30.895824],
['Alejandro Canizares (167)',40.416775,-3.70379],];
var infowindow = new google.maps.InfoWindow({}
var image = new google.maps.MarkerImage('images/marker11.gif',
new google.maps.Size(9,9), //size
null, //origin
null, //anchor
new google.maps.Size(9,9) //scale
);
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,
icon: image,
});
//when the map zoom changes, resize the icon based on the zoom level so the marker covers the same geographic area
google.maps.event.addListener(map, 'zoom_changed', function() {
var pixelSizeAtZoom4 = 9; //the size of the icon at zoom level 4
var maxPixelSize = 350; //restricts the maximum size of the icon, otherwise the browser will choke at higher zoom levels trying to scale an image to millions of pixels
var zoom = map.getZoom();
var relativePixelSize = Math.round(pixelSizeAtZoom4*Math.pow(1.2,zoom)); // use 2 to the power of current zoom to calculate relative pixel size. Base of exponent is 2 because relative size should double every time you zoom in
if(relativePixelSize > maxPixelSize) //restrict the maximum size of the icon
relativePixelSize = maxPixelSize;
if(zoom < 4) //when zooming < 4, fix pixel size to 9
relativePixelSize = 9;
//change the size of the icon
marker.setIcon(
new google.maps.MarkerImage(
marker.getIcon().url, //marker's same icon graphic
null,//size
null,//origin
null, //anchor
new google.maps.Size(relativePixelSize, relativePixelSize) //changes the scale
)
);
});
