Question

通过以下示例，

https://google-developers.appspot.com/maps/documentation/javascript/examples/place-search

通过使用附近的搜索，其中一个地方返回是“John St Square Supermarket”。如何在完整的谷歌地图中生成一个网址来显示“John St Square Supermarket”？现在我通过将经度和经度附加到“http://maps.google.com/?q=”来生成http://maps.google.com/?q=123,456 但它不会显示地方的名称和正确的标记。

然后我尝试了http://maps.google.com/?q=John St Square Supermarket

工作良好......直到我偶然发现了一个有多个地点的地名。例如，

http://maps.google.com/?q=SK%20Dato%27%20Abu%20Bakar

它显示了多个位置，但我只需要一个我已经知道它的纬度和经度是什么。

Answer 1

您可以使用参数ll：

将纬度和经度添加到网址

https://maps.google.com/?q=pizza+hut&ll=-33.867701,151.208471

您还可以使用参数z：

为用户指定默认缩放级别

https://maps.google.com/?q=pizza+hut&ll=-33.867701,151.208471&z=12

Answer 2

PlacesResult.url属性代表Google地方信息的网址。 https://developers.google.com/maps/documentation/javascript/reference#PlaceResult

所以你可以这样做：
