说明：  JQuery 学习方式：积极主动的自学！学习期：让自己与众不同，就业后：更多的晋升机会。 什么是JQuery？ 1、 一个可以提高你工作效率的工具。 2、 一个辅助javascript开发的库。极大的简化了javascript编程。（类比java的工具包：lang包、IO包、集合包） 3、 宗旨是：write less,do more(写得更少,做得更多) 4、 原理是：对javascript进行二次封装，定义了全新的获取元素和操作元素的方式。 例如：document.getElementById(“id”) ——》$(“#Id”) 是不是简化了很多
(JQuery Learning mode: active self-learning. Learning period: make yourself different from others: after employment: more opportunities for promotion. What is JQuery? 1, a tool that can improve your work efficiency. 2, an auxiliary JavaScript development library. Greatly simplifies the JavaScript programming. (analogous to Java's Toolkit: Lang package, IO package, collection pack) 3, the purpose is: write less, do more (write less, do more). 4. The principle is: the second encapsulation of javascript, defined a new way to obtain elements and operational elements. For example: document.getElementById ("Id") - "$" ("#Id") is it a lot simpler?)
