在对象中添加方法的问题

Question

I have this object:

var Point = {
    step: function () {
        alert("hello");
    }
};

This works: Point.step(); .

How to make it work with the [ ] notation? Meaning Point["property_name"] .

Answer 1

It is Point["step"](); . Here is the snippet:

 var Point = { step: function () { alert("hello"); } }; Point["step"]();
