我有一个要求，我希望 Google Maps API 有一个解决方案。我从未使用过 Google Maps API - 所以我对此很陌生。
在网站主页上有一个表单，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）还有一个名为商店名称的第二个字段 - 当用户开始输入商店名称时 - 我想获取该城市中具有该名称的所有商业列表并将其显示为下拉列表，用户可以从中选择适当的分支。无需在地图上显示任何内容。例如 - 如果休斯顿的用户开始输入 McDonalds，则应开始显示以下商家信息
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并且我们需要对其进行解析，或者我们是否获取不同的字段街道名称、城市、州、邮政编码等
任何信息或示例将不胜感激谢谢
我不认为你想要谷歌地图。首先，使用条款除了在可公开访问的网页上的谷歌地图上显示内容外，不允许任何其他用途，其次，还有另一个谷歌 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“企业”：你将不得不从某个地方获取这些数据——我不相信谷歌有这方面的服务。也许您可以简单地使用 Google 搜索 API 和一些逻辑来仅查找企业 ( http://code.google.com/apis/ajaxsearch/ )
编辑：我对于企业来说，也许你可以看看这个样本：http ://code.google.com/apis/ajaxsearch/samples.html#local-search
更新：这是使用google clientlocation api和 localsearch 使用 jsonp 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企业。他们的 API 也比 google 的更简单易用。
