我想在绘制多边形选中时更改标记图标。在addMarker()中,标记从JSON数据中解析并推送到allMarkers数组中。未选中时图标为红色,选中后图标将变为白色。
function addMarker(lat,lng,i){
var myLatlng = new google.maps.LatLng(lat,lng);
var marker = new google.maps.Marker({
position: myLatlng,
icon: "http://labs.google.com/ridefinder/images/mm_20_red.png",
map: map
});
marker.shapeId = '0';
allMarkers.push(marker);
}
function selectMarkersInPoly() {
alert(allMarkers.length)
for (var i=0; i < createdShapes.length; i++) {
for (var j=0; j < allMarkers.length; j++){
var latlong = allMarkers[j].getPosition();
if(google.maps.geometry.poly.containsLocation(latlong, createdShapes[i]) == true) {
allMarkers[j].shapeId = createdShapes[i].id;
allMarkers[j].setOptions({
icon : "http://labs.google.com/ridefinder/images/mm_20_white.png"
});
}
}
}
}
selectMarkersInPoly()有什么问题???谢谢您的帮助?

这不是javascript匿名对象的正确语法:
allMarkers[j].setOptions({
icon = "http://labs.google.com/ridefinder/images/mm_20_white.png"
});
(我认为你会在javascript控制台中出现javascript错误) 这应该有效:
allMarkers[j].setOptions({
icon: "http://labs.google.com/ridefinder/images/mm_20_white.png"
});
