使用GoogleMapsAPI 3.0和FusionTablesAPI 1.0检索InfoWindowContent

我最近收到了Google发来的一封电子邮件,建议我更新我的地图代码。我按照Migration Guide上的说明进行操作。除infoWindow外,现在一切正常。当我输入地址并点击搜索时,它会正确地删除地图上的图钉,但不会打开带有相应内容的infoWindow。这是我认为不正确的代码段。

var script = document.createElement("script");

    script.setAttribute("src","https://www.googleapis.com/fusiontables/v1/query?sql=SELECT * FROM " +
        tableid + " WHERE ST_INTERSECTS(geometry, CIRCLE(LATLNG(" + coordinate.lat() + "," + coordinate.lng() + "), 0.1))&jsonCallback=addInfoWindow");
    document.getElementsByTagName("head")[0].appendChild(script);

我已经尝试了jsonCallback和回调参数。两者都产生相同的结果。

感谢您的协助。

addInfoWindow() *

function addInfoWindow(response) {

 infowindow.close();

if(response.table.rows.length) {
    infowindow.close();
     initialize();
    infowindow.setContent("Content removed: " + response.table.rows[0][1] + response.table.rows[0][0]);
    infowindow.setPosition(coordinate);
    map.setCenter(coordinate);
    map.setZoom(15);
    infowindow.open(map);
}
else
{
infowindow.close();
initialize();

    infowindow.setContent("Nothing here.");
    infowindow.setPosition(coordinate);
    map.setCenter(coordinate);
    map.setZoom(15);
    infowindow.open(map);
}

}

更新:generateInfoWindow()

function generateInfoWindow(results, status) {

    initialize();

if (status == google.maps.GeocoderStatus.OK) {
    initialize();
    //center and zoom map
    coordinate = results[0].geometry.location;

    marker = new google.maps.Marker({
        map: map,
        layer: layer,
        animation: google.maps.Animation.DROP,
        position: coordinate
    });
    map.setCenter(results[0].geometry.location);
    map.setZoom(15);






    var script = document.createElement("script");

   script.setAttribute("src","https://www.googleapis.com/fusiontables/v1/query?sql=SELECT * FROM " +
    tableid + " WHERE ST_INTERSECTS(geometry, CIRCLE(LATLNG(" + coordinate.lat() + "," + coordinate.lng() + ")))&key=" + apiKey +  " &callback=addInfoWindow()");
document.getElementsByTagName("head")[0].appendChild(script);

} else {
    alert("Please make sure you entered your City and State");
}

}

尝试类似:“...)& key =”+ apiKey +“& callback = addInfoWindow()”

这里有一些示例代码,专注于从Fusion Table检索数据。 https://docs.google.com/file/d/0B5KVZ6J1ohN_dktpWXBmSzNkdjg/edit

我猜你不想要这部分:),0.1)) ......而且你确实需要API密钥。

希望有所帮助,
