在下面的代码中有两个类别,我想按类别显示自定义图标而不是标记。这两个类别的平均值我想为每个类别显示两个自定义图标。但是我很难弄清楚它。

答案 0 :(得分:1)
为您的类别创建一系列图标:
var icons = ["",
"http://maps.google.com/mapfiles/ms/micons/blue.png",
"http://maps.google.com/mapfiles/ms/micons/green.png"];
使用它来填充标记的icon
属性:
for (i = 0; i < beaches.length; i++) {
newMarker = new google.maps.Marker({
position: new google.maps.LatLng(beaches[i][1], beaches[i][2]),
map: map,
icon: icons[beaches[i][3]],
title: beaches[i][0]
});
