jQuery是一个快速、简洁的JavaScript框架，是继Prototype之后又一个优秀的JavaScript代码库（框架）于
                2006年1月由John Resig发布。jQuery设计的宗旨是“write Less，Do More”，即倡导写更少的代码，做更
                多的事情。它封装JavaScript常用的功能代码，提供一种简便的JavaScript设计模式，优化HTML文档操作、事件
                处理、动画设计和Ajax交互。
            
jQuery的核心特性可以总结为：具有独特的链式语法和短小清晰的多功能接口；具有高效灵活的CSS选择器，并且可
                对CSS选择器进行扩展；拥有便捷的插件扩展机制和丰富的插件。jQuery兼容各种主流浏览器，如IE 6.0+、FF 1.5+、
                Safari 2.0+、Opera 9.0+等。
