获取对象内部的函数名称

Question

Here is my code:

var structure = {
A: function() {
    this.B();
},

B: function() {
      console.log(arguments.callee.caller.toString());
}

};

Then I run:

structure.A();

As you understand, I'm trying to get caller function name, but result is empty string. Are any ideas how to do that?

Answer 1

I've added the function name A, and slightly changed the statement that gets the string to print. Does this do what you want?

var structure = {
    A: function A() {
        this.B();
    },
    B: function() {
        console.log(arguments.callee.caller.name);
    }
}

structure.A();
