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
