如何在Windows Store應用程序中捕獲webview的輕掃手勢？

Question

林建立一個Windows應用商店應用程序（8.1），我使用webview控件加載html文件。我需要趕上後面的代碼中的web視圖的拖/滑事件。我該怎麼做？

Answer 1

試試這個

public MainPage() 
    { 
     this.InitializeComponent(); 

     webView.ManipulationMode = ManipulationModes.TranslateX | ManipulationModes.TranslateInertia ; 
     webView.ManipulationStarted += webView_ManipulationStarted; 
     webView.ManipulationDelta += webView_ManipulationDelta; 
    } 

    Point start; 
    void webView_ManipulationDelta(object sender, ManipulationDeltaRoutedEventArgs e) 
    { 
     if (e.IsInertial) 
     { 
      int threshold = 500; 
      if (start.X - e.Position.X > threshold) //swipe left 
      { 
       e.Complete(); 

       //do something here 
      } 
     } 
    } 
    void webView_ManipulationStarted(object sender, ManipulationStartedRoutedEventArgs e) 
    { 
     start = e.Position; 
    }

頭可以使用LinqToVisualTree找到網頁視圖的邊界，並獲得事件他們。

因此其他響應的代碼變爲：

public MainPage() 
{ 
    this.InitializeComponent(); 

    var border = webView.Descendants<Border>().Last() as Border; 

    border.ManipulationMode = ManipulationModes.TranslateX | ManipulationModes.TranslateInertia ; 
    border.ManipulationStarted += webView_ManipulationStarted; 
    border.ManipulationDelta += webView_ManipulationDelta; 
} 

Point start; 
void webView_ManipulationDelta(object sender, ManipulationDeltaRoutedEventArgs e) 
{ 
    if (e.IsInertial) 
    { 
     int threshold = 500; 
     if (start.X - e.Position.X > threshold) //swipe left 
     { 
      e.Complete(); 

      //do something here 
     } 
    } 
} 
void webView_ManipulationStarted(object sender, ManipulationStartedRoutedEventArgs e) 
{ 
    start = e.Position; 
}
