Question

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

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

or

Answer 1

As many times as you like. They fire in order of declaration.

$(document).ready() will fire when the document is ready (when it's all loaded by the browser). The other one will fire as soon as that part of the script executes.
