WPF WebBrowser屏蔽彈出alert ，confirm ，prompt ，showModalDialog() ，window.open()

添加Microsoft.mshtml.dll,然后寫如下代碼

void browser_Navigated(object sender, NavigationEventArgs e) {
            txtUrl.Text = e.Uri.ToString();
            WebBrowser wbWebBrowser = (WebBrowser)sender;
            StringBuilder msgb = new StringBuilder();
            msgb.AppendLine("function alert(){return;}");
            msgb.AppendLine("function confirm(){return;}");
            msgb.AppendLine("function showModalDialog(){return;}");
            msgb.AppendLine("function window.open(){return;}");
            msgb.AppendLine("function prompt(){return;}");
            string strJS = msgb.ToString();
            IHTMLWindow2 win = (IHTMLWindow2)(wbWebBrowser.Document as IHTMLDocument2).parentWindow;
            win.execScript(strJS, "Javascript");
            win = null;
        }
