Hello all,

In our project we want to be able to call a 'static method' or 
class-like method from C or C++.

With the compilable and executable javascript below I've tried to 
accomplish this:

XYZHandler = function(name)
{
this.name = name || "untitled";
}

XYZHandler.prototype = new Object();
XYZHandler.superclass = Object.prototype;
XYZHandler.prototype.constructor = XYZHandler;

XYZHandler.onOpen = function()
{
....
}

XYZHandler.onClose = function()
{
....
}

onOpen = function()
{
....
}

onClose = function()
{
}

XYZHandler.main = function(argc, argv)
{
var handler = new XYZHandler("Handler1");
XYZHandler.onOpen();
XYZHandler.onClose();
onOpen();
onClose();
}

XYZHandler.main();

I now want to call functions XYZHandler.onOpen() or XYZHandler.onClose() 
  from my C++ environment:

void CallFunction()
{
jsval result = 0L;

JSScript* script = JS_CompileFile(context, globalObj, sourceFile);
JSBool ok = JS_ExecuteScript(context, globalObj, script, &result);
if (not ok)
    {
    ...
    }

ok = JS_CallFunctionName(context, globalObj, "XYZHandler.onOpen",  0, 
NULL, &result);
if (not ok)
     {
     ...
     }

....
}


My 'ErrorReporter' now says: 'TypeError: undefined is not a function'.

If I however use the function name "onOpen" 
[JS_CallFunctionName(context, globalObj, "onOpen",  0,  NULL, &result)] 
, the JS_CallFunctionName succeeds.

How can one call these class-like or static methods?

With kind regards,
Peter Paulus
