我有一个要求，希望Google地图API能够提供解决方案。我从未使用过Google Maps API - 所以我非常陌生。
在网站首页有一个表单，当用户访问时，我希望发生以下情况：
1）根据IP填充城市字段中的用户所在城市
2）有第二个名为“商店名称”的字段 - 当用户开始输入商店名称时，我希望获取该城市中所有具有该名称的商家列表，并将其显示为下拉菜单，用户可以从中选择合适的分支机构。不需要在地图上显示任何内容。 例如 - 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列表:
此外，当我们从Google API获得商家地址时 - 我们会得到一个字符串还是不同的字段，如街道名称、城市名称、州/省份、邮政编码等？
任何信息或示例将非常感激 谢谢
我认为您可能不需要使用谷歌地图。首先，使用条款不允许除在公共网页上显示谷歌地图之外的其他用途；其次，还有另一个完全符合您需求的谷歌API：客户端位置API：http://code.google.com/apis/ajax/documentation/#ClientLocation
关于“企业”方面的问题：您需要从某个地方获取这些数据 - 我不认为谷歌提供该服务。也许您可以简单地使用谷歌搜索API和一些逻辑来查找只有企业信息的结果（http://code.google.com/apis/ajaxsearch/）
编辑：针对企业信息，也许您可以参考以下示例：http://code.google.com/apis/ajaxsearch/samples.html#local-search
更新：以下是使用Google ClientLocation API和jsonp进行本地搜索的示例。
