Google map V3 Set Center to specific Marker

I am using Google Map V3 to display a list of markers pulled from a DB, using MYsql and PHP. MY markers are set on the map using the full address (from DB, including postcode) as I don't have the Long,Lat info All is working fine, MY loop looks as follow

while...
Addmarker(map,'MY ADdress','Title');
end while;

Now I would like to set the map to a specific marker contained in the loop that will match a previously entered postcode. How can I set the map to center to this marker and open the infowindow?

Solution 1:

Once you have markers on the map, you can retrieve the Lat/Long coordinates through the API and use this to set the map's center. You'll first just need to determine which marker you wish to center on - I'll leave that up to you.

// "marker" refers to the Marker object you wish to center on

var latLng = marker.getPosition(); // returns LatLng object
map.setCenter(latLng); // setCenter takes a LatLng object

Info windows are separate objects which are typically bound to a marker, so to open the info window you might do something like this (however it will depend on your code):

var infoWindow = marker.infoWindow; // retrieve the InfoWindow object
infoWindow.open(map); // Trigger the "open()" method

Hope this helps.

Solution 2:

To build upon @6twenty's answer...I prefer panTo(LatLng) over setCenter(LatLng) as panTo animates for smoother transition to center "if the change is less than both the width and height of the map". https://developers.google.com/maps/documentation/javascript/reference#Map

The below uses Google Maps API v3.

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(latitude, longitude),
    title: markerTitle,
    map: map,
});
google.maps.event.addListener(marker, 'click', function () {
    map.panTo(marker.getPosition());
    //map.setCenter(marker.getPosition()); // sets center without animation
});

Solution 3:

This should do the trick!

google.maps.event.trigger(map, "resize");
map.panTo(marker.getPosition());
map.setZoom(14);

You will need to have your maps global

Solution 4:

may be this will help:

map.setCenter(window.markersArray[2].getPosition());

all the markers info are in markersArray array and it is global. So you can access it from anywhere using window.variablename. Each marker has a unique id and you can put that id in the key of array. so you create marker like this:

window.markersArray[2] = new google.maps.Marker({
            position: new google.maps.LatLng(23.81927, 90.362349),          
            map: map,
            title: 'your info '  
        });

Hope this will help.
