如何从fnRender返回值将数据分配给mData

Question

我在Google地图中使用DataTable。我从服务器端json获得经度和纬度。这里我改变了地址，并将该地址分配给DataTable数据（TD）。坚持它会给出错误。

var geocoder;
    geocoder = new google.maps.Geocoder();
        var DataTable = $('#DataTable').dataTable({

            "sAjaxSource": "php/totalDevices.php",
            "aoColumns": [{
                "mData": "name",
                "sTitle": "User Name"
            }, {
                "mData": "managerName"
            }, {
                "mData": "imei"
            }, {
                "mData": "email"
            }, {
                "mDataProp": null,
                "mData": null,
                "fnRender":function ( obj ) {
                    var latlng = new google.maps.LatLng(obj.aData['latitude'], obj.aData['longitude']);
                    geocoder.geocode({
                        'latLng': latlng
                    }, function (results, status) {
                        if (status == google.maps.GeocoderStatus.OK) {
                            if (results[0]) {
                                var address = results[0].formatted_address;
                                console.log(address);
                                return address;
                                //callback(address);
                            } else {
                                alert('No results found');
                            }
                        } else {
                            alert('Geocoder failed due to: ' + status);
                        }
                    });
                    //return getAddress(obj.aData['latitude'],obj.aData['longitude']);
                },

            }],

        });
