C#Webbrowser Ajax调用

WebBrowser控件(WPF和WinForms版本)的行为在许多方面与完整的IE不同。您可能希望实现功能控件以使其行为尽可能接近IE(尤其是

FEATURE_BROWSER_EMULATION
),这通常可以解决脚本兼容性问题。这是一些代码,请注意,它
不需要管理员权限 即可运行:

private void SetBrowserFeatureControlKey(string feature, string appName, uint value){    using (var key = Registry.CurrentUser.CreateSubKey(        String.Concat(@"SoftwareMicrosoftInternet ExplorerMainFeatureControl", 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(@"SOFTWAREMicrosoftInternet 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;}

您应该提出自己的一组功能,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();//...}

更新后
,我目前正在使用并推荐可以在此处找到的一组功能。
