WPF WebBrowser屏蔽弹出alert ，confirm ，prompt ，showModalDialog() ，window.open()
添加Microsoft.mshtml.dll,然后写如下代码

void browser_Navigated(object sender, NavigationEventArgs e) {

            txtUrl.Text = e.Uri.ToString();//显示当前的url

            WebBrowser wbWebBrowser = (WebBrowser)sender;

            StringBuilder msgb = new StringBuilder();

            msgb.AppendLine("function alert(){return;}");

            msgb.AppendLine("function confirm(){return;}");;

            msgb.AppendLine("function window.open(){return;}");

            msgb.AppendLine("function prompt(){return;}");

            IHTMLWindow2 win = (IHTMLWindow2)(wbWebBrowser.Document as IHTMLDocument2).parentWindow;

            win.execScript(msgb.ToString(), "Javascript");

            win = null;

        }
