我在设置google map api中多个标记的信息窗口时遇到问题。基本上,我从外部Json文件获得纬度和经度以及其他所有内容。我正在解析它,因为标记显示在地图上。但是,当我尝试为每一个添加信息窗口时,它只显示最近添加的标记的信息窗口+每当我指向不同的标记时,它仍将转到显示其信息窗口的最新标记。这是源代码:
function initialize()
{
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 1,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("tab14"), myOptions);
/* Sets up markers */
markers = [];
for (var i = 0, coordinates; coordinates = data.coords[i]; i++)
{
//marker = new google.maps.LatLng(coordinates.latitude, coordinates.longitude);
var iconImage = new google.maps.MarkerImage("http://map.lgfl.org.uk/images/arrow_green.png");
var LatLng = new google.maps.LatLng(coordinates.latitude, coordinates.longitude);
var marker = new google.maps.Marker({position: LatLng, icon: iconImage });
var contentString = '<div>'+
'<div>'+
'</div>'+
'<h4>'+coordinates.title+'</h1>'+
'<div>'+
'<p>'+coordinates.excerpt+'</p>'+
'</div>'+
'</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
markers.push(marker);
}
/* Sets up marker clusterer */
var markerCluster = new MarkerClusterer(map, markers);
}
有人可以给我一些帮助吗?感谢。

所以我改变了它,现在它看起来像这样:
infoWindow = new google.maps.InfoWindow();
for (var i = 0, coordinates; coordinates = data.coords[i]; i++)
{
//marker = new google.maps.LatLng(coordinates.latitude, coordinates.longitude);
var iconImage = new google.maps.MarkerImage("http://map.lgfl.org.uk/images/arrow_green.png");
var LatLng = new google.maps.LatLng(coordinates.latitude, coordinates.longitude);
var marker = new google.maps.Marker({position: LatLng, icon: iconImage });
var contentString = '<div>'+
'<div>'+
'</div>'+
'<h4>'+coordinates.title+'</h1>'+
'<div>'+
'<p>'+coordinates.excerpt+'</p>'+
'</div>'+
'</div>';
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent(contentString);
infoWindow.open(map,marker);
});
markers.push(marker);
}
/* Sets up marker clusterer */
var markerCluster = new MarkerClusterer(map, markers);
仍然无效:/

据我所知,你只能有一个InfoWindow。您应该为每个标记添加一个onclick事件,您可以在其中定义窗口的内容。
我认为你应该改变:
var infowindow = new google.maps.InfoWindow({
content: contentString
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
类似于:
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
infoWindow应该在for循环之外定义。
祝你好运!**编辑**
我认为您需要为标记使用唯一的名称。
这是一个有效的例子:

var latLng = new google.maps.LatLng(25.271139,55.307485);
var marker2 = new google.maps.Marker({

marker2.onclick = function() {

infoWindow.open(map,marker2);

google.maps.event.addListener(marker2, 'click', function() {

您可能需要更改密钥。但在我的地方,这就像一个魅力。我能给你的最简单的例子。

好的,我找到了解决方法。这有点像黑客,但它对我有用。我把它放在这里以防其他人需要它:
<script type="text/javascript">
/* Sets up the map with markers */
function initialize()
{
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 1,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("tab14"), myOptions);
/* Sets up markers */
markers = [];
infoWindow = new google.maps.InfoWindow();
for (var i = 0, coordinates; coordinates = data.coords[i]; i++)
{
var iconImage = new google.maps.MarkerImage("http://map.lgfl.org.uk/images/arrow_green.png");
var LatLng = new google.maps.LatLng(coordinates.latitude, coordinates.longitude);
var marker = new google.maps.Marker({position: LatLng, icon: iconImage });
var contentString = '<div>'+
'<h4>'+coordinates.title+'</h1>'+
'<div>'+
'<p>'+coordinates.excerpt+'</p>'+
'</div>'+
'</div>';
addMarker(marker, contentString);
markers.push(marker);
}
/* Sets up marker clusterer */
var markerCluster = new MarkerClusterer(map, markers);
function addMarker(marker, content)
{
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent(content);
infoWindow.open(map, marker);
});
}
}
</script>
