Google Map不在Firefox中居中

Question

I've got a strange issue with a google map, which I can only duplicate in Firefox. To explain, we have a static map which when clicked on enlarges to a full interactable map with a marker in the center. This works fine in all browsers, except Firefox. In Firefox, what happens is the map is not centered correctly. The marker is placed, however, it is in the top left corner of the map just outside of the visible area.

Any ideas? This has been baffling me for a while.

JavaScript:

// lat and lng are initialized earlier
var latlng = new google.maps.LatLng(lat, lng);
var myOptions = {
    zoom: 13,
    center: latlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP,
};

var map = new google.maps.Map($("#map_canvas")[0], myOptions);

var marker = new google.maps.Marker({
    position: latlng,
    map: map,
    icon: icon
});

var resizeMap = function () {
    $("#smallMap, #smallMapOverlay").remove();
    $("#map_canvas").show();
    google.maps.event.trigger(map, 'resize');
    map.setCenter(latlng, 13);
};

$("#smallMapOverlay").live("click", function (e) {
    e.preventDefault();
    resizeMap();
});

CSS:

#map_canvas {
    width: 640px;
    height: 377px; 
}

Karim79' fix works. I worked it out in a slightly different way. If you have a wrapper class to handle mapping functions, you could create a reset function like so,

function reset(){
        setTimeout(function(){gm.event.trigger(_gMap, 'resize');}, 50);
        setTimeout(function(){_gMap.setCenter(settings.mapOptions.center);}, 100);
    }

It seems that putting the resize and setCenter methods into show() 's callback, and giving a tiny delay fixes the issue.

var resizeMap = function () {
    $("#smallMap, #smallMapOverlay").remove();
    $("#map_canvas").show(10, function () {
        google.maps.event.trigger(map, 'resize');
        map.setCenter(latlng, 13);
    });
};

It's not the most elegant solution, but it works.
