嗨，我正在根据此示例制作 map http://econym.org.uk/gmap/example_categories.htm并尝试向其中添加地理定位，但每次我尝试添加地理定位代码时，它都会破坏代码的其余部分，所以我希望有人能指出我如何让它工作的正确方向
我是 Google map 和地理定位新手
如果之前有人问过这个问题，我很抱歉我找不到我需要的答案
这是我在 index.html 页面中使用的代码

最佳答案
首先，在包含 Google Maps API 时，您必须使用 sensor=true
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
关于javascript - 将地理位置添加到现有的谷歌地图，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/10762453/
