Question

我正在尝试在Google Maps应用程序中实现ASP.Net MVC地址自动填充功能。 Google示例来自此处：https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform

它在html文件中运行良好且简单，但当我尝试在MVC视图中实现它时 - 下拉地址框未显示。我的Google密钥包含在API参考中，数据包可在Chrome“网络”标签中看到。

我正在研究这个问题很多时间，尝试过不同的方法 - 目前还没有成功。例如，我试图在“脚本”@section中包含脚本 - 也不成功。

我可以在“div”标记之后看到"pac-container"类scripts，但由于某种原因，当我输入地址时，样式“display：none”不会删除在html文件中：

我正在使用Visual Studio 2015 MVC5模板。 MVC查看来源位于：

我找到了问题的原因并修复了它。它是由Visual Studio中的设置损坏引起的。
