Google地图无法使用剃刀进行渲染

Question

我已经按照Nava的建议从mapCanvas css中删除了浮动：

#mapCanvas {
    width: 500px;
    height: 400px;
    /*float: left;*/
}

我还在视图末尾删除了对jQuery的第二个引用...

#mapCanvas {
  width: 500px;
  height: 400px;
  float: left;
}
#infoPanel {
  float: left;
  margin-left: 10px;
}
#infoPanel div {
  margin-bottom: 5px;

嗨，我一直在努力让这个代码在我的Mvc网站中运行，但我找不到为什么不渲染的原因。我在一个新项目中有完全相同的代码，它工作正常，但不在我的。

这是我的代码......我发现有效的项目的唯一区别是 JavaScript版本1.10.2与我实际使用的2.2.1。即使在这个代码片段中代码也能正常运行......我正在失去理智！

您已将网址添加到您的网站，我看了一下。当您尝试创建google.maps.Map时，您似乎收到了Javascript错误。

这是我开始调查的地方。

在旁注中，您将包含两次jQuery，但/Scripts/jquery-1.10.2.min.js将返回404。
