我已经找到了很多有关如何向Google Maps添加自定义标记的代码，但是几乎没有关于在同一张地图上使用不同标记的任何代码。例如，我可能要在“高级自定义字段”转发器字段中使用绿色标记显示4个标记，而与自定义帖子类型相关的其余标记将显示为灰色标记。
我尝试了几种不同的方法，例如复制marker变量以及更改名称和颜色，但是我尝试的所有操作都会破坏地图的某些部分。
这是我需要的两种不同类型地图标记的屏幕截图：http : //screencast.com/t/Cc5eE7St
下面的代码可以工作，但这只是标记的一种。

夏洛特（Charlotte），您可以在构建标记时向每个标记对象添加一个“数据标记”属性，如下所示（在需要它们的位置，绿色/灰色）
<div class="marker" data-lat="<?php echo $location['lat']; ?>" data-lng="<?php echo $location['lng']; data-marker="green/grey" ?>">
然后在javascript中，您可以使用在代码中设置的数据标记检查标记类型，如下所示
var grayCircle = {
//path: 'M -1,0 A 1,1 0 0 0 1,0 1,1 0 0 0 -1,0 z',
path: google.maps.SymbolPath.CIRCLE,
fillColor: '#888888',
fillOpacity: 1,
scale: 3,
strokeColor: "#888888",
strokeWeight: 3
};
var greenMarker = //create your marker here
//Check your marker type, if it's green then set that otherwise leave it grey
var markerType = $marker.attr('data-marker')=="green"?greenMarker:greyCircle;
var marker = new google.maps.Marker({
position: latlng,
//Set your marker using markerType here
icon: markerType,
map: map
});
