Google Maps JavaScript Places API - 未定义网址

标签: javascript google-maps

我正在将Google Maps API集成到我正在处理的网站中。在大多数情况下,它按预期执行;但是,在拨打附近的搜索服务时,我很难获得返回的网址(到该位置的Google地图页面)。根据我对Google文档的理解,此调用返回一个PlaceResult对象,其中包含各种属性,包括url。我能够正确访问其他两个属性,名称和附近,但url属性将以未定义的形式返回。问题可能是什么?感谢。

相关的代码段:

var keyword =  document.getElementById("searchBox").value;
var requestOptions = {
location: { lat: 37.3011339, lng: -89.5770238},
radius: '5000',
keyword: keyword
};

placesService = new google.maps.places.PlacesService(hotelMap);
placesService.nearbySearch(requestOptions, findCallback);

});

}; // end initiallize

function findCallback(results, status) {

var resultsList = "";


  if (status == google.maps.places.PlacesServiceStatus.OK) {

    for (var i = 0; i < results.length; i++) {

       alert(results[i].url); // this returns undefined           
     resultsList += "<li>" + results[i].name + ": " + results[i].vicinity + " - <a href='" + results[i].url + "'>View Details</a></li>";

    }

    document.getElementById("searchList").innerHTML = resultsList;



  } 
}

答案 0 :(得分:1)

看起来PlaceResult查询中返回的nearbySearch中的属性不可用。来自该查询返回的结果的placeId的详细请求,返回该属性可用的结果。

根据我对文档的阅读,唯一应该返回&#34;限制&#34; PlaceResultradarSearch,但这似乎不是它的工作方式。
