我对使用其 HTML 导入到 Boilerplate 3 的 Google 地图进行了相当简单的改编。我需要激活密钥吗？（如果我这样做了，我希望得到某种形式的信息更丰富的错误消息。）我的代码出现空白屏幕；代码是：

我不知道 Boilerplate 做了什么，所以我对发布的源代码做了尽可能少的更改：

(1) 在#map_canvas 样式中，后面的逗号改为分号height: 100%

（2）divrole="main"也需要height: 100%，所以我给了它一个idwrapper并添加了一个合适的样式

(3) jQuery include 应该http:在 URL 前面有

(4)initialize最终jQuery函数调用内部的调用是不必要的，因为脚本包含在load_scripthas 中callback=initialize。无论如何，在包含地图 JS 之前调用地图代码是行不通的。
