Ok... given the following code and the assumptions that cx, globalObj
and parentObj were defined in earlier code:

JSObject* myArray	= JS_NewArrayObject(cx, 2, NULL);
JS_AddRoot(cx, myArray);

JSObject* myObj1;
JSObject* myObj2;
rval myval1;
rval myval2;

myObj1 = JSMyObject::JSInit(cx, globalObj, NULL);  
myval1 = OBJECT_TO_JSVAL(myObj1);

myObj2 = JSMyObject::JSInit(cx, globalObj, NULL);  
myval2 = OBJECT_TO_JSVAL(myObj2);

JS_SetElement(cx, myArray, 0, &myval1);
JS_SetElement(cx, myArray, 1, &myval2);

JS_DefineProperty(cx, parentObj, "myarray", OBJECT_TO_JSVAL(myArray),
NULL, NULL, JSPROP_ENUMERATE);

What code allows me to determine which array value was used?  Does the
getProperty routine for parentObj indicate which index was used?  If
not how do I read which myarray index was accessed?

Reason for the question:  I want each of the array objects to be
"bound" to a member of an array in the original program.  The index of
the myarray object directly correlates with the index of the program's
array.  This would eliminate the need for a variable in each object
indicating the index it is associated with and also eliminate code
associated with setting and reading that variable.

Thank you in advance for any help.
