$("a")或$(document) [英] $("a") or $(document)

问题描述

$("a")或$(document)真正做什么?他们是如何定义的?(我知道这是一个$函数)

我只是自己浏览jQuery.我发现jQuery语法非常特殊，并且定义不明确. (我想大多数人只是想记住为什么jQuery要求每个人都要做)为什么有人可以阐明jQuery为什么要做它的原因.


谢谢！

What does $("a") or $(document)really do? How did they define it?(I know it''s a $ function)

I am just going through the jQuery by myself. I found the jQuery syntax is very peculiar, and not well defined. ( I guess most people just try to remember the why the jQuery requires everyone to do) Can anyone shed some light on the why jQuery does what it does.



Thanks!
