下面列出了在Google地图中设置标记的代码。但是只设置了一个标记,而应设置了四个标记。
此代码有什么问题?

答案 0 :(得分:1)
我能够通过改变点的标记来标记多个点。在显然添加到地图之前应该标记点。但是我无法设置多个信息窗口。无论单击哪个标记,都只显示一个信息窗口。 udpated代码如下 -
function setMarkers(map,locations){ for(var i = 0; i&lt; locations.length; i ++){ var location = locations [i]; if(location!= undefined){ var latlngbounds = new google.maps.LatLngBounds(); var point = new google.maps.LatLng(location [1],location [2]);
latlngbounds.extend(point);
var myLatLng = new google.maps.LatLng(location[1], location[2]);
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: location[3],
zIndex: location[0]
});
var content = "<a href='" + location[4] + "'><strong>" + location[3] + "</strong></a>";
var infowindow = new google.maps.InfoWindow({
content: content
});
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: location[3]
});
google.maps.event.addListener(marker, 'click', function () {
infowindow.open(map, marker);
});
}
map.setCenter(latlngbounds.getCenter());
}
}
