Google Maps API v3 - TypeError: Result of expression 'google.maps.LatLng' [undefined] is not a constructor
提问by Steve Kemp
I'm creating a static html page to display a number of locations from a data. I've just copied one of the samples and are working backwards but I'm getting the following error in the Safari Inspector:
我正在创建一个静态 html 页面来显示数据中的多个位置。我刚刚复制了其中一个示例并正在向后工作，但在 Safari Inspector 中出现以下错误：
main.js:1SyntaxError: Parse error
sample.htm:10TypeError: Result of expression 'google.maps.LatLng' [undefined] is not a constructor.
Here's my html code:
这是我的 html 代码：

}

<body onLoad="initialize()">

I'm not sure what I'm doing wrong here - it actually works in IE v8 on Windows but not in Safari and I need to get it working for both.
我不确定我在这里做错了什么 - 它实际上可以在 Windows 上的 IE v8 中运行，但不能在 Safari 中运行，我需要让它同时适用于两者。

Add callback function to your google maps request. It'll be executed after Google loads everything it needs.
向您的谷歌地图请求添加回调函数。它将在 Google 加载所需的一切后执行。
