屏蔽webbrowser的網頁彈出是js錯誤。

 private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {

            webBrowser1.Document.Window.Error += new HtmlElementErrorEventHandler(Window_Error);
            
           
        }
        void Window_Error(object sender, HtmlElementErrorEventArgs e)
        {
            e.Handled = true;
        }

記得要在webbrowser的事件上綁定

webBrowser1_DocumentCompleted
