谷歌的演示了這個片段捕捉，通過分頁，從一個地方搜索超過20個結果：超過20結果通過分頁與谷歌Places API的
service.nearbySearch(request, resultList, function(status, results, pagination) {
if (status != google.maps.places.PlacesServiceStatus.OK) {
return;
}
resultList.addPlaces(results);
if (pagination.hasNextPage) {
resultList.button.onClick = pagination.nextPage;
}
});
我有問題想這個片段integret成以下例如，Github中的另一個谷歌地圖示例gmaps-samples-v3：

任何人都可以幫忙嗎？請提供一些關於此問題的指示（指針）。
非常感謝！我會研究你的代碼。謝謝！！ – 2012-08-02 08:12:32
有沒有辦法避免延遲並一次顯示60個項目？ http://stackoverflow.com/questions/12426796/google-places-returns-60-items-with-2s-interval – 2012-09-14 14:54:49
不是我所知道的。 api強加限制。 – 2012-10-01 03:39:56
