Replace arguments.callee inside of new Function

Some string is converted into function by new Function(...) call.

How can I get referent to this function inside of the string without using arguments.callee?

var f = new Function('return arguments.callee.smth');
f.smth = 128;
f(); // 128
Solution

  • The only way to do such thing is to use closure.

    For example:

    var f = (function () {
  var f = new Function('return this().smth').bind(function () { return f });
  return f;
})();

f.smth = 128;
f();

    Or so:

    var f = (function (g) {
  return function f() {
    return g.apply(f, arguments)
  };
})(new Function('return this.smth'));

f.smth = 128;
f();

    Anyway, seems like arguments.callee works inside constructed function regardless strict mode.
