Hi everybody.
I try to get return value of function. But I can't do that.
I show my code here, anybody has a hint, please help me.
Thank you very much.

void JSDB::JSDB_GetReturnValueFunction(wxString function)
{	 
	if(function=="") 
	{
		wxMessageBox("No Script");
		return;
	}
   const char * source = (const char *)function;
   JSBool         ok           = JS_FALSE;
   JSString     * str          = NULL;
   JSFunction   * func          = NULL;
   const char   * argNames [1] = { "vartest" };
   jsval          argValues[1] = { INT_TO_JSVAL(10) };
   char         * fileName     = NULL;
   uintN          lineNum=0;
   jsval          result;
   
   func = JS_CompileFunction(data->cxDebugger, m_jsGlobalObject,
"testFunc",
                             1, argNames,
                             source, strlen(source),
                             fileName, lineNum);	
   if (NULL == func)
   {
      return;
   }	   
   ok = JS_CallFunction(data->cxDebugger, m_jsGlobalObject, func, 1,
argValues,&result);
   if (JS_TRUE == ok)
   {
      str = JS_ValueToString(data->cxDebugger, result);
   }
   else
   {
		return;
   }
	//------------------------------------
   wxString ret="return value of function: ";
   ret += wxString::Format(" %s",JS_GetStringBytes(str));
   return;
}

wxString temp;
temp = "function testget(vartest) { var test=10; test=test*vartest;
return test; }"
JSDB_GetReturnValueFunction(temp);
//data->cxDebugger is a context
