推荐答案

让我猜猜:您正在使用 WebControl.您最初导航到的页面可能会尝试通过 Javascript 重定向到具有协议扩展名(如 facebook://)的 URI(这解释了为什么 IsScriptEnabled 没有问题的原因是错误的).

Let me try to guess: you are using a WebControl. The page you initially navigate to probably tries to redirect to an URI that has a protocol extension (like facebook://) via Javascript (that explains why you don't have the problem with IsScriptEnabled is false).

Windows Phone 尝试使用本机应用打开该链接.如果您没有知道如何处理该协议的应用，它会在应用商店中启动搜索以查找能够处理该协议的应用.

Windows Phone tries to open that link with a native app. If you don't have an app that knows how to handle that protocol, it launches a search on the Store to find an app that does.

您可以做的是订阅 WebBrowser 的 Navigating 事件并查看它重定向的位置.

What you can do is subscribe to the Navigating event of the WebBrowser and look where it redirects.

在 Navigating 事件中，如果您想停止该行为，请将 e.Cancel 设置为 true.

In the Navigating event, set e.Cancel to true if you want to stop that behaviour.
