我可以在页面上声明多少次jQuery的文档就绪功能? [英] How many times can I have jQuery's document ready function declared on a page?

问题描述

允许在页面上声明jQuery文档ready函数多少次，即:

How many times is it permitted to have the jQuery document ready function declared on a page, i.e.:

$(function () { ... });

或

$(document).ready(function () { ... });

两者之间有区别吗?

如果允许一个以上，它们会按声明顺序开火吗?

If it's permitted more than one, do they fire in order of declaration?

推荐答案

一个:两者没有区别.

报价:

All three of the following syntaxes are equivalent:

$(document).ready(handler)
$().ready(handler) (this is not recommended)
$(handler)

两个:您可以根据需要拥有任意数量的对象，它们将按照执行$()或$(document).ready()函数的顺序执行. (即，每个处理程序都添加到了队列中)

Two: You can have as many of them as you wish, and they will be executed in the order that the $() or $(document).ready() functions are executed. (i.e. each handler is added to the queue)
