屏蔽脚本错误弹窗

使用的是System.Windows.Controls.WebBrowser时使用如下代码

        private void Browser_Navigated(object sender, NavigationEventArgs e)
        {
            var fiComWebBrowser = typeof(WebBrowser).GetField("_axIWebBrowser2", BindingFlags.Instance | BindingFlags.NonPublic);
            if (fiComWebBrowser == null)
                return;

            object objComWebBrowser = fiComWebBrowser.GetValue(browser);
            if (objComWebBrowser == null)
                return;

            objComWebBrowser.GetType().InvokeMember("Silent", System.Reflection.BindingFlags.SetProperty, null, objComWebBrowser, new object[] { true });
        }

使用的是 System.Windows.Forms.WebBrowser时只需将WebBrowser的ScriptErrorsSuppressed设置为true

            browser.ScriptErrorsSuppressed = true;

处理弹出新窗口

WPF中的WebBrowser 详情见监听WPF的WebBrowser控件弹出新窗口的事件

WinFrom中的WebBrowser

通过NewWindow事件加以处理，代码如下：

 private void InnerBrowser_NewWindow(object sender, System.ComponentModel.CancelEventArgs e)
        {
            e.Cancel = true;
            try
            {
                InnerBrowser.Navigate(InnerBrowser.StatusText);
            }
            catch (Exception ex)
            {

            }
        }
