问题描述
我不是在问什么是适当的链接语法，我知道它可能是这样的:
I am not asking what is the appropriate syntax for chaining, I know it could be something like:
$('myDiv').removeClass('off').addClass('on');
但是我真的很想了解它的内部工作原理，据我所知，链接是相对于其他著名框架的优势之一，但是对于像我这样的新手程序员来说，这对于我们来说非常抽象，我敢肯定有没有人可以为我提供解释，让我了解链接的工作原理.
However I'm really curious to understand the inner working of it, as far as I know chaining is one of the advantages against other famous frameworks but this us to much abstraction for a novice programer like me, I'm sure there is someone out there that can provide me with a explanation that allows me to understand how chaining works.
谢谢！
推荐答案
如果你有一个带有某些方法的对象，如果每个方法返回一个带有方法的对象，你可以简单地从返回的对象中调用一个方法.
If you have an object with certain methods, if each method returns an object with methods, you can simply call a method from the object returned.
var obj = { // every method returns obj---------v
first: function() { alert('first'); return obj; },
second: function() { alert('second'); return obj; },
third: function() { alert('third'); return obj; }
}
obj.first().second().third();
