Comet, long polling with jquery tutorial
提问by oshirowanen
I am looking to add comet long polling functionality to my site by using ajax and jquery as I am not familiar with the javascript prototype framework. However, when I search for this, I always seem to end up with tutorial which use the prototype framework. Does anyone know of any comprehensive tutorial for comet long polling based on jquery and ajax?
我希望通过使用 ajax 和 jquery 向我的网站添加 Comet 长轮询功能，因为我不熟悉 javascript 原型框架。然而，当我搜索这个时，我似乎总是以使用原型框架的教程结束。有没有人知道基于 jquery 和 ajax 的彗星长轮询的综合教程？

Comet and Long polling imply writing part of your code in client side and part on server side. You would need in server CometD or Ape to been able to connect to a Comet server, i find that installing them are usually a pain in the ass.
Comet 和 Long 轮询意味着在客户端编写部分代码，在服务器端编写部分代码。您需要在服务器 CometD 或 Ape 中才能连接到 Comet 服务器，我发现安装它们通常很麻烦。
The option that i have found way more easy is to have Node.js with a "comet" module. Faye(also available for ruby) is a long pole pub sub server quite usefull for chats and Socket Io is a great way to have a page updated constantly to sockets(websockets with flash fallback).
我发现更简单的选择是让 Node.js 带有一个“彗星”模块。Faye（也可用于 ruby）是一个长杆 pub 子服务器，对于聊天非常有用，而 Socket Io 是将页面不断更新到套接字（具有闪存回退的 websockets）的好方法。

I have a very simple example here that can get you started with comet. It covers compiling Nginx with the NHPM module and includes code for simple publisher/subscriber roles in jQuery, PHP, and Bash.
我这里有一个非常简单的例子，可以让你开始使用 Comet。它涵盖了使用 NHPM 模块编译 Nginx，并包括用于 jQuery、PHP 和 Bash 中的简单发布者/订阅者角色的代码。
