内部函数是外部函数的属性吗？

Question

Function.prototype.test = function(){return "F"}
function hh(){var x="xx";function test(){return "f"}}

print(hh.test());

the result is "f", does that mean the inner function is a property of outer function?

== updated my code, but the result is still "f". !_!

Answer 1

The result should be an error - and at least in Chrome, it is.

test inside hh is a local function, and it should not be accessible from outside.

As for Function.test , it is a property of Function - not a member of all functions. If you actually want to make something a member of all functions, it needs to be added to Function.prototype

Answer 2

You actually managed to get a result from this code? You are trying to print the result.

hh.test will be undefined as test is being defined privately to hh. Defining test on the prototype Function.prototype.test would return 'F' from hh.test in this instance.
