C#webbrowser Ajax调用

我正在使用embedded在C#WPF .NET4应用程序中的webbrowser控件。 每当我手动按下表格中的button,浏览器挂在“您的请求正在处理”消息,什么也没有发生。 如果我在完整的IE浏览器中做同样的事情,那么页面通常会得到处理结果。 我错过了什么? 谢谢button后面的代码如下

<a onclick="startSearch();" href="javascript:void(-1);" name="btnNext" class="btn floatLe noClear btnSubmit btnRight"> <span>Continue</span> </a>

    更新 ,我目前使用和推荐一系列可以在这里find的function。


    WebBrowser控件(WPF和WinForms版本)的行为与完整的IE有很多不同之处。 您可能需要实施function控制,以使其行为尽可能接近IE(特别是FEATURE_BROWSER_EMULATION )。 希望这个问题将会消失。 这里是一些代码:

     private void SetBrowserFeatureControlKey(string feature, string appName, uint value) { using (var key = Registry.CurrentUser.CreateSubKey( String.Concat(@"Software\Microsoft\Internet Explorer\Main\FeatureControl\", feature), RegistryKeyPermissionCheck.ReadWriteSubTree)) { key.SetValue(appName, (UInt32)value, RegistryValueKind.DWord); } } 

    例如:

     private void SetBrowserFeatureControl() { // http://msdn.microsoft.com/en-us/library/ee330720(v=vs.85).aspx // FeatureControl settings are per-process var fileName = System.IO.Path.GetFileName(Process.GetCurrentProcess().MainModule.FileName); // make the control is not running inside Visual Studio Designer if (String.Compare(fileName, "devenv.exe", true) == 0 || String.Compare(fileName, "XDesProc.exe", true) == 0) return; SetBrowserFeatureControlKey("FEATURE_BROWSER_EMULATION", fileName, GetBrowserEmulationMode()); // Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode. SetBrowserFeatureControlKey("FEATURE_AJAX_CONNECTIONEVENTS", fileName, 1); SetBrowserFeatureControlKey("FEATURE_ENABLE_CLIPCHILDREN_OPTIMIZATION", fileName, 1); SetBrowserFeatureControlKey("FEATURE_MANAGE_SCRIPT_CIRCULAR_REFS", fileName, 1); SetBrowserFeatureControlKey("FEATURE_DOMSTORAGE ", fileName, 1); SetBrowserFeatureControlKey("FEATURE_GPU_RENDERING ", fileName, 1); SetBrowserFeatureControlKey("FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI ", fileName, 0); SetBrowserFeatureControlKey("FEATURE_DISABLE_LEGACY_COMPRESSION", fileName, 1); SetBrowserFeatureControlKey("FEATURE_LOCALMACHINE_LOCKDOWN", fileName, 0); SetBrowserFeatureControlKey("FEATURE_BLOCK_LMZ_OBJECT", fileName, 0); SetBrowserFeatureControlKey("FEATURE_BLOCK_LMZ_SCRIPT", fileName, 0); SetBrowserFeatureControlKey("FEATURE_DISABLE_NAVIGATION_SOUNDS", fileName, 1); SetBrowserFeatureControlKey("FEATURE_SCRIPTURL_MITIGATION", fileName, 1); SetBrowserFeatureControlKey("FEATURE_SPELLCHECKING", fileName, 0); SetBrowserFeatureControlKey("FEATURE_STATUS_BAR_THROTTLING", fileName, 1); SetBrowserFeatureControlKey("FEATURE_TABBED_BROWSING", fileName, 1); SetBrowserFeatureControlKey("FEATURE_VALIDATE_NAVIGATE_URL", fileName, 1); SetBrowserFeatureControlKey("FEATURE_WEBOC_DOCUMENT_ZOOM", fileName, 1); SetBrowserFeatureControlKey("FEATURE_WEBOC_POPUPMANAGEMENT", fileName, 0); SetBrowserFeatureControlKey("FEATURE_WEBOC_MOVESIZECHILD", fileName, 1); SetBrowserFeatureControlKey("FEATURE_ADDON_MANAGEMENT", fileName, 0); SetBrowserFeatureControlKey("FEATURE_WEBSOCKET", fileName, 1); SetBrowserFeatureControlKey("FEATURE_WINDOW_RESTRICTIONS ", fileName, 0); SetBrowserFeatureControlKey("FEATURE_XMLHTTP", fileName, 1); } private UInt32 GetBrowserEmulationMode() { int browserVersion = 7; using (var ieKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer", RegistryKeyPermissionCheck.ReadSubTree, System.Security.AccessControl.RegistryRights.QueryValues)) { var version = ieKey.GetValue("svcVersion"); if (null == version) { version = ieKey.GetValue("Version"); if (null == version) throw new ApplicationException("Microsoft Internet Explorer is required!"); } int.TryParse(version.ToString().Split('.')[0], out browserVersion); } UInt32 mode = 11000; // Internet Explorer 11. Webpages containing standards-based !DOCTYPE directives are displayed in IE11 Standards mode. Default value for Internet Explorer 11. switch (browserVersion) { case 7: mode = 7000; // Webpages containing standards-based !DOCTYPE directives are displayed in IE7 Standards mode. Default value for applications hosting the WebBrowser Control. break; case 8: mode = 8000; // Webpages containing standards-based !DOCTYPE directives are displayed in IE8 mode. Default value for Internet Explorer 8 break; case 9: mode = 9000; // Internet Explorer 9. Webpages containing standards-based !DOCTYPE directives are displayed in IE9 mode. Default value for Internet Explorer 9. break; case 10: mode = 10000; // Internet Explorer 10. Webpages containing standards-based !DOCTYPE directives are displayed in IE10 mode. Default value for Internet Explorer 10. break; default: // use IE11 mode by default break; } return mode; } 

    你应该拿出你自己的一套function ,并在WebBrowser初始化之前注册它们,例如,在主窗体构造函数中:

     public MainWindow() { SetBrowserFeatureControl(); InitializeComponent(); //... }
