是否有 YUI 2 自定义事件发布/订阅事件模型的 jQuery 等效项？

我学习了如何使用 YUI 2 库在 Javascript 中进行开发，并且想知道是否有相当于自定义事件的 jQuery (http://developer.yahoo.com/yui/event/#customevent）

具体来说，我希望能够定义自定义事件，而不必最初附加侦听器。

在 YUI 中，我将创建一个页面类并声明可以订阅的不同自定义事件。下面是一些示例代码来演示我想要做什么，但是使用 jQuery

function ListPage() {
    var me = this;
    this.initEvent = new YAHOO.util.CustomEvent("initEvent");

    this.init = function() {
         // initialize events, DOM, etc
         this.initEvent.fire(me);
    }
}

在应用程序 Javascript 中，我想订阅 initEvent。

var page = new ListPage();
page.initEvent.subscribe(
    function (type, args) {
        // do stuff here
    }
);

page.init();

jQuery 中有类似的教程/示例吗？

我知道我可以使用bind()和trigger()做类似的事情，但我得到的印象是当我调用bind()时我必须传递一个事件处理程序。

是否可以在 jQuery 中创建自定义事件，但稍后传入事件处理程序？

我希望我的问题有意义。谢谢！

I learned how to develop in Javascript using the YUI 2 library and was wondering if there were a jQuery equivalent of Custom Events (http://developer.yahoo.com/yui/event/#customevent)

Specifically, I want to be able to define custom events without having to attach the listeners initially.

In YUI, I would create a page class and declare different custom events that can be subscribed to. Below is some example code to demonstrate what I want to do, but with jQuery

function ListPage() {
    var me = this;
    this.initEvent = new YAHOO.util.CustomEvent("initEvent");

    this.init = function() {
         // initialize events, DOM, etc
         this.initEvent.fire(me);
    }
}

In application Javascript, I would then like to subscribe to the initEvent.

var page = new ListPage();
page.initEvent.subscribe(
    function (type, args) {
        // do stuff here
    }
);

page.init();

Are there any tutorials/examples of something like this in jQuery?

I understand I can do something similar using bind() and trigger(), but the impression I get is I have to pass in an event handler when I call bind().

Is it possible in jQuery to create the custom event, but pass in the event handler later?

I hope my question makes sense. thanks!
