google maps how to add marker if I know the latitude and longitude
提问by Anastasie Laurent
Before, I was adding the marker on click like this:
之前，我在点击时添加标记，如下所示：
google.maps.event.addListener(map, 'click', function(event) {
marker = new google.maps.Marker({
position: event.latLng,
map: map
});
and that was working find, but now I want to add a marker depending on the latitude and longitude not depending on the click event.
那是有效的查找，但现在我想根据纬度和经度添加一个标记，而不是根据点击事件。
I tried this:
我试过这个：
if (("#latitude").val() && (("#longitude").val())){
marker = new google.maps.marker({
});
}
but I still don't know what parameter should I pass. Could you help me please?
但我仍然不知道我应该传递什么参数。请问你能帮帮我吗？
many thanks
非常感谢

map.addOverlay(new GMarker(
new GLatLng(-33.9417, 150.9473)));
var point = new GLatLng(-33.9417, 150.9473);
map.setCenter(point, 10);
var marker = new GMarker(point);
map.addOverlay(marker);
