google maps - simple javascript for loop not behaving the way I think it should -

- 

for (var i=0; i<gmaps.map.markers.length; i++) {   google.maps.event.addlistener(gmaps.map.markers[i].serviceobject, 'click', function(object){     alert(gmaps.map.markers[i]);    }); };

so, goes through loop. i'm using google maps api, obviously. each of markers on map has alert attached it. alert shows undefined though. if switch alert(gmaps.map.markers[0]); or other applicable number, shows me object object, should. if call alert(gmaps.map.markers[i].id); or like, value i'm looking for, obviously, every marker gives same alert.

why i not being recognized in callback?

you have privatize i:

for (var i=0; i<gmaps.map.markers.length; i++) {  (function(i){   google.maps.event.addlistener(gmaps.map.markers[i].serviceobject, 'click', function(object){     alert(gmaps.map.markers[i]);    });  }(i)); };
