JavaScript - 使用数组符号将 function 添加到原型

Question

Is it possible to do something like that?

Foo.add_function = function (callback_name, callback_function) {
    this.prototype[callback_name] = callback_function;
}

I need to add a function to prototype in array notation. Thank you.

Answer 1

Yes.
A prototype is a normal object; that will work fine.

Note that this will only work if this is a function; otherwise, prototype won't exist.

Answer 2

Apparently, yes:

jsfiddle is great, you should check it out when you want to test out simple stuff like this.
