获取函数原型的源代码

Question

Let's say I do the following:

String.prototype.myFunc = function(){ /* code here */ }

I have just created a new method, myFunc , that will be available for each string ( "This is a test".myFunc() ).

My question is: Is it possible, and if it is, how, to get the source code of myFunc programatically? (This is inside Node)

Answer 1

您可以使用位于Function.prototype上的toString方法将函数作为字符串获取。

var funcSource = String.prototype.myFunc.toString();
