using Windows.UI.Xaml.Controls;

public class CustomWebView : WebView
{
    protected override void OnNavigationStarting(WebViewNavigationStartingEventArgs e)
    {
        if (e.Uri == null)
        {
            // 后退操作
            if (e.NavigationMode == WebViewNavigationMode.Back)
            {
                if (CanGoBack)
                {
                    GoBack();
                    e.Cancel = true; // 取消导航
                }
            }
            // 前进操作
            else if (e.NavigationMode == WebViewNavigationMode.Forward)
            {
                if (CanGoForward)
                {
                    GoForward();

                }
            }
