在knockout.js 中，为什么“这个"被分配给“自己"? [英] In knockout.js, why "this" is being assigned to "self"?

问题描述

我正在学习 Knockoutjs 教程.有一件事对我来说似乎很奇怪.我目前在第 2 部分:

I am working through Knockoutjs tutorial. And one thing seems weird to me. I am currently in part 2:

http://learn.knockoutjs.com/#/?tutorial=collections

在每个类"的这一部分中，这个"被分配给自我"......第一个不是这种情况?

And in this part in every "class", "this" is being assigned to "self".. it was not the case in the first one?

为什么会有人这样做?是否只是编写特定代码的人对 Python 上瘾了，或者这有什么实际好处?

Why would someone do this? Is it just whoever wrote that particular code has python addiction, or is there some actual benefits to this?

推荐答案

由于this"根据上下文指代不同的对象，因此可以通过将其分配给另一个变量来保存对特定对象的引用，例如self".

Since "this" refers to different objects depending on context, one can save a reference to a particular object by assigning it to another variable, for example "self".
