通过jquery的$()引用元素包括通过id、class、元素名以及元素的层级关系及dom或者xpath条件等方法，且返回的对象为jquery对象（集合对象），不能直接调用dom定义的方法。

2、jQuery对象与dom对象的转换
只有jquery对象才能使用jquery定义的方法。注意dom对象和jquery对象是有区别的，调用方法时要注意操作的是dom对象还是 jquery对象。
普通的dom对象一般可以通过$()转]]>https://blog.youkuaiyun.com/gaogaowws/article/details/5720954https://blog.youkuaiyun.com/gaogaowws/article/details/5720954gaogaowwsThu, 08 Jul 2010 14:31:00 +0800业务需求：在线练习考试，每次考试有100道试题。每页显式一道题目，通过翻页按钮显式下一题或者上一题。
               每次翻页，题目部分刷新，其余部分不动。
 
实现方法：后台一次性获取本次练习考试的所有试题，返回给前台页面的一个数组。根据页码，从数组中取得当前页对应的题目。

      DWR（Direct Web Remoting）是一个用于改善web页面与Java类交互的远程服务器端Ajax开源框架。它可以允许在浏览器里的代码使用运行在WEB服务器上的JAVA函数,就像它们是浏览器的本地代码(客户端代码)一样.
