Question

我正在我的通用Windows应用程序中集成支付网关，我在webview中打开URL。但是，webview似乎无法显示javascript警报消息或弹出窗口。我在网上看到我需要在软件包清单中添加网站的url以启用Scriptnotify事件，但鉴于它是支付网关，为所有银行网站添加网址是不可行的。有办法解决这个问题吗？

此外，我正在处理ScriptNotify事件，但这似乎是部分正确的。

private async  void MyWebView_ScriptNotify(object sender, NotifyEventArgs e)
    {
        Windows.UI.Popups.MessageDialog dialog = new Windows.UI.Popups.MessageDialog(e.Value);

        await dialog.ShowAsync(); 
    }


private async void MyWebView_NavigationCompleted(WebView sender, WebViewNavigationCompletedEventArgs args)
    {
        string result = await this.MyWebView.InvokeScriptAsync("eval", new string[] { "window.alert = function (AlertMessage) {window.external.notify(AlertMessage)}" });

    }

在敲了一两个星期之后，终于找到了解决方案，以下是必要的事件处理程序：

private async void MyWebView_NavigationCompleted(WebView sender, WebViewNavigationCompletedEventArgs args)
    {
            string result = await this.MyWebView.InvokeScriptAsync("eval", new string[] { "window.confirm = function (ConfirmMessage) {window.external.notify(ConfirmMessage)}" });
    }


private async void MyWebView_ScriptNotify(object sender, NotifyEventArgs e)
    {

            Windows.UI.Popups.MessageDialog dialog = new Windows.UI.Popups.MessageDialog(e.Value);
            dialog.Commands.Add(new UICommand("Yes"));
            dialog.Commands.Add(new UICommand("No"));

            // Set the command that will be invoked by default
            dialog.DefaultCommandIndex = 0;

            // Set the command to be invoked when escape is pressed
            dialog.CancelCommandIndex = 1;

            var result = await dialog.ShowAsync();

            if (result.Label.Equals("Yes"))
            {
                string res = await MyWebView.InvokeScriptAsync("eval", new string[] { "window.confirm = function (ConfirmMessage) {return true}" });
            }
            else
            {
                string res = await MyWebView.InvokeScriptAsync("eval", new string[] { "window.confirm = function (ConfirmMessage) {return false}" });
            }
    }

无法在支付网关
