我有一个C＃/ WPF应用程序，该应用程序使用WebBrowser控件，该控件将网站作为其主要界面（用于自助服务终端）。该网站可以通过javascript调用C＃方法进行一些本地处理。一切正常，直到我设置了'FEATURE_BROWSER_EMULATION＆＃39; IE7以上（使用下面的代码）。当我执行javascript调用本机方法时，除非我从＆＃39; http://localhost＆＃39;运行网站，否则不会调用它。哪个工作正常。
我认为这是一个安全问题。我搞乱了IE中的所有安全设置（包括将网站设置为“受信任的网站”），但我似乎无法使其正常运行。
编码我使用设置仿真：
private void SetBrowserCompatibilityMode()
{
// 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 );
if ( String.Compare( fileName, "devenv.exe", true ) == 0 ) // make sure we're not running inside Visual Studio
return;
using ( var key = Registry.CurrentUser.CreateSubKey( @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION",
RegistryKeyPermissionCheck.ReadWriteSubTree ) )
{
// Webpages containing standards-based !DOCTYPE directives are displayed in IE10 Standards mode.
UInt32 mode = 11000; // 11000 = IE11, 10000 = IE10, 9000 = IE9, 8000 = IE8, 7000 = IE7;
key.SetValue( fileName, mode, RegistryValueKind.DWord );
}
using ( var key = Registry.CurrentUser.CreateSubKey( @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_ZONE_ELEVATION",
RegistryKeyPermissionCheck.ReadWriteSubTree ) )
{
// disable zone elevation prevention
UInt32 mode = 0;
key.SetValue( fileName, mode, RegistryValueKind.DWord );
}
using ( var key = Registry.CurrentUser.CreateSubKey( @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BLOCK_LMZ_SCRIPT",
RegistryKeyPermissionCheck.ReadWriteSubTree ) )
{
// enable <scripts> in local machine zone
UInt32 mode = 0;
key.SetValue( fileName, mode, RegistryValueKind.DWord );
}
using ( var key = Registry.CurrentUser.CreateSubKey( @"Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_NINPUT_LEGACYMODE",
RegistryKeyPermissionCheck.ReadWriteSubTree ) )
{
// disable Legacy Input Model
UInt32 mode = 0;
key.SetValue( fileName, mode, RegistryValueKind.DWord );
}
}

禁用FEATURE_LOCALMACHINE_LOCKDOWN，FEATURE_BLOCK_LMZ_SCRIPT，FEATURE_BLOCK_LMZ_OBJECT功能。您可以从here调整工作的C＃代码。或者，我相信您可以使用"Mark of Web"重新运行脚本。

尝试以下方法之一： 1-以管理员身份运行程序。 2-检查您的JavaScript是否与您正在模拟的版本兼容，因为某些JavaScript代码在IE7上运行但不在上面。
更新： 这是我设置仿真的方法，请注意，如果您不以管理员身份运行此代码，则此代码将无效：
def execute(connection: Connection, procedure: GPProcedure, ps: GPProcedureParameterSet) = {
val cs = connection.prepareCall(procedure.toString)
var index = 0
for (parameter <- ps.parameters) {
index = index + 1
parameter match {
// Handle any IN (or INOUT) types: If the optional value is None, set it to NULL, otherwise, map it according to
// the actual object value and type encoding:
case p: GPOut => cs.registerOutParameter(index, p.parameterType)
case GPIn(None, t) => cs.setNull(index, t)
case GPIn(v: Some[_], Types.NUMERIC | Types.DECIMAL) => cs.setBigDecimal(index, v.get.asInstanceOf[java.math.BigDecimal])
case GPIn(v: Some[_], Types.BIGINT) => cs.setLong(index, v.get.asInstanceOf[Long])
case GPIn(v: Some[_], Types.INTEGER) => cs.setInt(index, v.get.asInstanceOf[Int])
case GPIn(v: Some[_], Types.VARCHAR | Types.LONGVARCHAR) => cs.setString(index, v.get.asInstanceOf[String])
case GPIn(v: Some[_], Types.CHAR) => cs.setString(index, v.get.asInstanceOf[String].head.toString)
case GPInOut(None, t) => cs.setNull(index, t)
// Now handle all of the OUT (or INOUT) parameters, these we just need to set the return value type:
case GPInOut(v: Some[_], Types.NUMERIC) => {
cs.setBigDecimal(index, v.get.asInstanceOf[java.math.BigDecimal]); cs.registerOutParameter(index, Types.NUMERIC)
}
case GPInOut(v: Some[_], Types.DECIMAL) => {
cs.setBigDecimal(index, v.get.asInstanceOf[java.math.BigDecimal]); cs.registerOutParameter(index, Types.DECIMAL)
}
case GPInOut(v: Some[_], Types.BIGINT) => {
cs.setLong(index, v.get.asInstanceOf[Long]); cs.registerOutParameter(index, Types.BIGINT)
}
case GPInOut(v: Some[_], Types.INTEGER) => {
cs.setInt(index, v.get.asInstanceOf[Int]); cs.registerOutParameter(index, Types.INTEGER)
}
case GPInOut(v: Some[_], Types.VARCHAR) => {
cs.setString(index, v.get.asInstanceOf[String]); cs.registerOutParameter(index, Types.VARCHAR)
}
case GPInOut(v: Some[_], Types.LONGVARCHAR) => {
cs.setString(index, v.get.asInstanceOf[String]); cs.registerOutParameter(index, Types.LONGVARCHAR)
}
case GPInOut(v: Some[_], Types.CHAR) => {
cs.setString(index, v.get.asInstanceOf[String].head.toString); cs.registerOutParameter(index, Types.CHAR)
}
case _ => { Logger(s"Failed to match GPProcedureParameter in executeFunction (IN): index $index (${parameter.toString})") }
}
}
cs.execute()
// Now, step through each of the parameters, and get the corresponding result from the execute statement. If there is
// no result for the specified column (index), we'll basically end up getting a "nothing" back, which we strip out.
index = 0
val results: List[Any] = for (parameter <- ps.parameters) yield {
index = index + 1
parameter match {
case GPOut(Types.NUMERIC) | GPOut(Types.DECIMAL) => cs.getBigDecimal(index)
case GPOut(Types.BIGINT) => cs.getLong(index)
case GPOut(Types.INTEGER) => cs.getInt(index)
case GPOut(Types.VARCHAR | Types.LONGVARCHAR | Types.CHAR) => cs.getString(index)
case GPInOut(v: Some[_], Types.NUMERIC | Types.DECIMAL) => cs.getInt(index)
case GPInOut(v: Some[_], Types.BIGINT) => cs.getLong(index)
case GPInOut(v: Some[_], Types.INTEGER) => cs.getInt(index)
case GPInOut(v: Some[_], Types.VARCHAR | Types.LONGVARCHAR | Types.CHAR) => cs.getString(index)
case _ => {
Logger(s"Failed to match GPProcedureParameter in executeFunction (OUT): index $index (${parameter.toString})")
}
}
}
cs.close()
// Return the function return parameters (there should always be one, the caller will get a List with as many return
// parameters as we receive):
results.filter(_ != (()))
}
并使用该功能：
private static void SetIEVersioneKeyforWebBrowserControl(string appName, int ieval)
{
RegistryKey Regkey = null;
try
{
Regkey = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION", true);
//If the path is not correct or
//If user't have priviledges to access registry
if (Regkey == null)
{
_logger.Error("Application FEATURE_BROWSER_EMULATION Failed - Registry key Not found");
return;
}
string FindAppkey = Convert.ToString(Regkey.GetValue(appName));
//Check if key is already present
if (FindAppkey == ieval.ToString())
{
_logger.Debug("Application FEATURE_BROWSER_EMULATION already set to " + ieval);
Regkey.Close();
return;
}
//If key is not present or different from desired, add/modify the key , key value
Regkey.SetValue(appName, unchecked((int)ieval), RegistryValueKind.DWord);
//check for the key after adding
FindAppkey = Convert.ToString(Regkey.GetValue(appName));
if (FindAppkey == ieval.ToString())
{
_logger.Info("Application FEATURE_BROWSER_EMULATION changed to " + ieval + "; changes will be visible at application restart");
}
else
{
_logger.Error("Application FEATURE_BROWSER_EMULATION setting failed; current value is " + ieval);
}
}
catch (Exception ex)
{
_logger.Error("Application FEATURE_BROWSER_EMULATION setting failed; " + ex.Message);
}
finally
{
//Close the Registry
if (Regkey != null) Regkey.Close();
}
}
