WinRt WebView control handling navigation within t

问题:

I have a Metro app using a WebView control. I'm using NavigateToString to load a html file which may contain hyperlinks. What I then want to do is detect when one of these hyperlinks is selected and, instead of allowing navigation within the WebView control, to launch IE and view the page there instead.

Is this possible within the WinRT constraints, and if so, how?

So far, I've tried capturing the WebView_LoadCompleted() event, but although it does fire at the right time, I can't see any details about the URI from the NavigationEventArgs.

回答1:

Unfortunately this isn't possible directly because WebView does not include events like Navigating (which were present in Windows Phone).

Luckily Nick Randolph (brilliant Windows Phone and Windows 8 developer) has created a workaround using script events. He's got a great write up on his blog:
