How can I access a private variable when replacing a private function,
which originally had access to this variable, with another one? Or is it
just not possible?

If possible for your scenario, you could potentially use eval for
this. For example:

function MyClass(val)
{
var printIt = function () { window.alert("1:" + val); }
this.callPrintIt = function () { printIt(); }
this.setPrintIt = function (evalStr) { eval("printIt = " +
evalStr); }
}
 
var c = new MyClass("test");
c.callPrintIt();
c.setPrintIt("function () { window.alert(\"2:\" + val); }");
c.callPrintIt();

Thanks

No I never thought of eval() - for a lot of reasons. Anyway, it might
work in this example, but not in my real life problem, where a mousemove
listener is replaced by a custom function, which should still be able to
access the "hidden" variables of the object.
