I've been stuck on this for a few days now. I'm having issues adding multiple points to a map using v3 of the Javascript API.
我已经坚持了几天了。我在使用 Javascript API 的 v3 向地图添加多个点时遇到问题。
I read this threadand this threadand also this threadon SO and I've caught a few mistakes and made some changes, but I still can't quite get anything to display except for the HTML text in map_canvas.
我阅读了此线程和此线程以及SO 上的此线程，我发现了一些错误并进行了一些更改，但除了 .html 中的 HTML 文本外，我仍然无法显示任何内容map_canvas。
Any help is much appreciated. Thanks.

The problem is here:
问题在这里：
info_window.open(map, this);
It should be:
它应该是：
info_window.open(google_map, this);
because there's no variable here named map. Working version here: http://jsfiddle.net/nrabinowitz/2DBXY/
因为这里没有名为map. 这里的工作版本：http: //jsfiddle.net/nrabinowitz/2DBXY/
If you're not doing so yet, try using a tool like Firebug or the Chrome console - debugging Javascript is almost impossible without one.
如果您还没有这样做，请尝试使用 Firebug 或 Chrome 控制台之类的工具 - 如果没有，几乎不可能调试 Javascript。
