可串函数调用javascript [英] Chainable function calls in javascript

问题描述

如果我们使用此代码：

If we use this code:

function StringCon(arg) {
  return function (ar) {
   return arg + ar;

}
}
StringCon("hello")(" world")//-> "hello world"

有没有办法创建一个自动创建闭包的函数，我们可以传递任意数量的函数调用？ br />
例如，如果我想添加！怎么办？到我的字符串末尾

Is there a way to create a function that would create that closure automatically and we could pass as many function calls as we want?
For example, what if I wanted to add "!" to the end of my string

StringCon("hello")(" world")("!")

我需要手动创建另一个函数调用，是否可以通过编程方式添加它？



我尝试过：



我知道存在arguments属性，但是我可以将这些函数调用组合在一起并添加它们吗？

I would need to create another function call manually, is it possible to add it pro grammatically?

What I have tried:

I am aware about existence of "arguments" property but can I group these function calls together and add them?

推荐答案

我不知道它是如何工作的。但是下划线库有链函数。

这可以链接无穷无尽的函数列表，但不会自动结束闭包。



你需要调用result（）函数。



但你可以查看他们的代码来看看他们是如何做到的。



Underscore.js [ ^ ]

I don't know how it works. But the underscore library has a chain function.
This can chain an endless list of functions, but won't end the closure automatically.

You need to call the result() function.

But you could look a their code to see how they did it.
