我要实现的目标是在点击地标时将PlaceMarker的颜色更改为灰色。

我能够捕获点击事件，但我无法在加载后找到如何更改样式：

google.maps.event.addListener(_kml_layer, "click", function(obj) { 
        alert(obj.featureData.id);
    });

_kml_layer由以下函数定义：

_kml_layer = new google.maps.KmlLayer(
                    'http://www.mydomain.com/mykml.kml', 
                    {
                        suppressInfoWindows : true,
                        map : _map
                    });

Answer 1

使用KmlLayer，您无法在加载后更改样式（使用当前记录的API）。您需要使用新样式制作第二个KmlLayer并加载它或使用第三方kml解析器（如geoxml3或geoxml_v3）将kml转换为可以更改的本机google maps api对象。

geoxml3： http://code.google.com/p/geoxml3/

以下是使用geoxml3更改鼠标悬停时三个地标图标中的两个的示例： http://www.geocodezip.com/geoxml3_test/v3_geoxml3_kmltest_stylemap_marker.html?filename=http://www.geocodezip.com/geoxml3_test/rollover_kml.xml

geoxml_v3： http://code.google.com/p/geoxml-v3/

另一种选择是使用FusionTablesLayer，它可以动态设置风格，可以从kml填充
