Linking image to marker on google maps_问答_开发者

I have a custom marker on my map, and an image above the maps, which I would like to have on click, center the google map on the custom marker, the image is linked to. How would I do that with google api? I am terrible with figuring out what google api code could do this, could someone show me an example?

I am trying to add it to the companyimage variable

                title:"Train Station",
                zIndex: 2
            });

}

with jquery and google API V-3 you can use

$("#yourImage").click(function(e){
    YOURMAP.setCenter(mapLat,mapLng); // add real lng and lat 
});

point the var YOURMAP to the map and the lat and lng an it will center on the point and resize if needed.

http://code.google.com/intl/en/apis/maps/documentation/javascript/reference.html#Map

yourMap.panTo( yourMarker.getPosition() );

Youd need to do something like this:

<script>
$(document).ready(function(){
    $("#img").live('click',function(){
        var pos = new google.maps.LatLng(lat,lng);
        map.setCenter(pos);
    });
});
</script>

<script>
$(document).ready(function(){
    $("#img").live('click',function(){
        var pos = marker.getPosition();
        map.setCenter(pos);
    });
});
</script>

And make sure you change the id of your image to match the selector.

<img src='someimage.jpg' id ='img' />

Make sure you replace map with the name of your created map. Replace marker with the name of your created marker. And if using the first example, replace lat/lng with the correct positions.
