基本概念

?jQuery：?jQuery是一個快速、簡潔的JavaScript框架，是繼Prototype之后又一個優秀的JavaScript代碼庫（或JavaScript框架）。jQuery設計的宗旨是“write Less，Do More”，即倡導寫更少的代碼，做更多的事情。它封裝JavaScript常用的功能代碼，提供一種簡便的JavaScript設計模式，優化HTML文檔操作、事件處理、動畫設計和Ajax交互。

問題描述

1、腳本分離，不利于管理；

2、XMLHttpResquest方式繁瑣；

3、不能滿足一些DOM操作

問題分析?

如果對腳本整合，需要判斷URL，并且易班課群采用部分刷新，雖然URL會發生改變，但是無法觸發腳本，需要監控URL變化。

解決方案

注：完成從XMLHttpResquest到jQuery AJAX的重構，但只對部分DOM操作做了jQuery重構?

已完成對之前所有方案的整合。

此腳本已經是完整方案。?
