Question

我有一个要求，我希望Google Maps API能够提供解决方案。我从未使用过谷歌地图API - 所以我对此很新。

在网站主页上有一个表格，当用户来时，我希望发生以下事情：

1）城市字段应填充基于IP的用户城市

2）第二个字段称为商店名称 - 当用户开始键入商店名称时 - 我想在该城市中获取具有该名称的所有商家信息，并将其显示为用户可以从中选择的下拉列表适当的分支。地图上无需显示任何内容。 Egs - 如果休斯顿的用户开始输入麦当劳，则应开始显示以下商家信息

McDonalds，12 Pearland Ave，Houston TX
McDonalds，2600 Bary Area Blvd，Houston TX
McDonalds，262 Clearlake Blvd，Houston TX

此外，当我们从Google API获取商家信息的地址时 - 我们是否将其作为一个字符串获取，我们需要对其进行解析，或者我们是否将不同的字段显示为街道名称，城市，州，邮政编码等

任何信息或示例都将非常感激感谢

Answer 1

我认为你不想要谷歌地图。首先，除了在可公开访问的网页上显示Google地图上的内容之外，使用条款不允许任何其他用途，其次，还有另一种Google API可以完全满足您的需求：客户端位置API：http://code.google.com/apis/ajax/documentation/#ClientLocation

关于“商家”：你将不得不从某个地方获取数据 - 我不相信谷歌有这方面的服务。也许您可以简单地使用Google Search API和一些逻辑来仅查找商家（http://code.google.com/apis/ajaxsearch/）

编辑：我对于企业，也许您可以看一下这个样本：http://code.google.com/apis/ajaxsearch/samples.html#local-search

更新：以下是使用jsonp使用google clientlocation api和localsearch的示例。

如果您只是查找餐馆，请尝试使用Yelp的API。您可以在搜索范围内按名称搜索商家。它们的API比谷歌更简单易用。
