GoogleMap开发疑问：marker在循环体中出错，急死人

Question

[code="js"]
var locations=[
['Name0',0.0,0.0,0],['Name1',1.0,1.0,0],['Name2',2.0,2.0,0],['Name3',3.0,3.0,0],['Name41',4.0,4.0,1],['Name55',5.0,5.0,0],['Name6',6.0,6.0,1],['Name7',7.0,7.0,0],['Name8',8.0,8.0,1],['Name9',9.0,9.0,1]

];

for (var i = 0; i < locations.length; i++) {
var beach = locations[i];
var myLatLng = new google.maps.LatLng(beach[1], beach[2]);
//alert(beach[1]+","+beach[2]);
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: (beach[3]==0?image:image2),
title:beach[0]
});
google.maps.event.addListener(marker, 'click', function() {
alert(marker.getPosition());//点击任意一个overlay结果都是(9,9)。为何？？ :twisted:
});
}
[/code]

主要是使用了 js 闭包。导致的。

改成这样试试
google.maps.event.addListener(marker, 'click', function() {
var m = arguments[0];
return function() {
alert(m.getPosition());
}
}.call(marker, marker));
