人们为什么称jQuery $别名为“工厂"? [英] Why do people call the jQuery $ alias a 'factory'?

问题描述

在各种站点上，jQuery的$变量称为别名，在其他站点上，其称为工厂.我看了一下源代码，我认为前者是正确的.据我所知，这里定义了美元符号:

// Expose jQuery to the global object
return (window.jQuery = window.$ = jQuery);

这会将$和jQuery都设置为SAME别名； jQuery对象没有工厂".网站将$称为工厂"是否完全错误?

解决方案

我认为其中任一个都可以.美元符号当然是jQuery函数的别名，专门用作速记.如果有人将函数称为工厂，我认为这并不是$别名所特有的，而只是描述jQuery函数的一般功能，即使用各种不同类型的输入创建对象.

On various sites, jQuery's $ variable is referred to as an alias, and on others, it is referred to as a factory. I took a look at the source code, and I think the former is correct. As far as I can see, the dollar symbol is being defined here:

// Expose jQuery to the global object
return (window.jQuery = window.$ = jQuery);

This is setting both $ and jQuery to the SAME alias; there is no 'factory' for jQuery objects. Are the sites referring to $ as a 'factory' simply wrong?

解决方案

I think either is an okay term. The dollar sign is certainly an alias for the jQuery function, specifically to be used as a shorthand. If someone refers to the function as a factory, I don't think that's specific to the $ alias, but just describing what the jQuery function does in general, which is create objects from various different types of input.
