我正在尝试使用Google商家信息库检索地点详细信息。当您点击地点标记时,我希望能够看到地址,名称,网站等。
我正在使用以下教程: http://code.google.com/apis/maps/documentation/javascript/places.html
一切似乎进展顺利。在我的标记中,我可以显示名称和评级,但地址,网站和电话号码都显示为“未定义”。这是因为谷歌没有我在这些地方要求的信息吗?或者我做错了什么?
这是我正在使用的代码: var map; var infowindow;
function initialize() {
var pyrmont = new google.maps.LatLng(-33.8665433, 151.1956316);
map = new google.maps.Map(document.getElementById('map_canvas'), {
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: pyrmont,
zoom: 15
});
var request = {
location: pyrmont,
radius: 5000,
types: ['bar']
};
infowindow = new google.maps.InfoWindow();
service = new google.maps.places.PlacesService(map);
service.search(request, callback);
}
function callback(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
for (var i = 0; i < results.length; i++) {
createMarker(results[i]);
}
}
}
function createMarker(place) {
var placeLoc = place.geometry.location;
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(place.name + "<br />" + place.formatted_address +"<br />" + place.website + "<br />" + place.rating + "<br />" + place.formatted_phone_number);
infowindow.open(map, this);
});
}
非常感谢任何帮助或想法。
干杯。

您正在进行地方搜索,但不会返回您正在使用的所有字段:
http://code.google.com/apis/maps/documentation/javascript/places.html#place_search_responses
要获取地址,网站等,您还需要致电place.getDetails()
,并传递地方reference
。参见:
http://code.google.com/apis/maps/documentation/javascript/places.html#place_details_requests
粗略地说,您的代码将更改为:
function createMarker(place) {
var placeLoc = place.geometry.location;
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location
});
var request = { reference: place.reference };
service.getDetails(request, function(details, status) {
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(details.name + "<br />" + details.formatted_address +"<br />" + details.website + "<br />" + details.rating + "<br />" + details.formatted_phone_number);
infowindow.open(map, this);
});
});
}

基于上面的Mikes响应,我建议像下面这样将呼叫移到侦听器中。这样,仅当用户单击标记时才进行对API的调用,而不是在呈现许多标记的情况下进行数百次调用。
function createMarker(place) {
var placeLoc = place.geometry.location;
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location
});
var request = { reference: place.reference };
google.maps.event.addListener(marker, 'click', function() {
service.getDetails(request, function(details, status) {
infowindow.setContent(details.name + "<br />" + details.formatted_address +"<br />" + details.website + "<br />" + details.rating + "<br />" + details.formatted_phone_number);
infowindow.open(map, this);
});
});
}
