动态添加原型对象的属性 [英] Dynamically add properties to the prototype object

问题描述

我想知道动态添加属性到函数的原型对象的最佳方法（或者甚至是一个好主意）。

I was wondering the best way to dynamically add properties to the prototype object of a function (or if it's even a good idea).

这就是我来的（$ {


$ b

This is what I came up with:

['foo', 'bar'].forEach(function(method) {
    String.prototype[method] = resolve;
});

function resolve() {
    // Who the hell called me?
}

'str'.foo();

我正在调用相同的函数 resolve（）对于我添加的所有新属性，我需要检查谁调用了这个函数（该属性名称），以便根据该信息来计算一个实现。
这一切都是好奇的事情，我正在对疯狂的JavaScript API实现做一些测试。

I'm calling the same function resolve() for all the new properties I've added and I need to check who called the function (which property name) in order to figure an implementation based on that information. It's all a matter of curiosity, I'm doing some tests on crazy JavaScript API implementations.

你们有什么建议吗？ >

Do you guys have any suggestions for this?

推荐答案

['foo', 'bar'].forEach(function (method) {
    String.prototype[method] = function () {
        resolve(method);
    };
});

function resolve(method) {
    alert(method);
}

("hello world").foo();
("hello world").bar();
