在ASP.MVC中使用Ajax

Asp.net MVC 抛弃了Asp.net WebForm那种高度封装的控件，让我们跟底层的HTML有了更多的亲近。可以更*、更灵活的去控制HTML的结构、样式和行为。Asp.net MVC可以更便捷的使用Ajax,本文针对开发过程中的技术进行了简单的总结并制作了一个小练习进行巩固。

1.准备工作

使用VS创建MVC应用程序，可以使用空模板，添加Home控制器以及对应的视图

使用NuGet进行包管理，添加Jquert、easyui等引用

2.开始制作Demo

UI：

3.演示

(1) 通过实体帮助类构造泛型 学生 对应 成绩列表进行显示（模拟数据库操作）

(2) 用户可以输入学生姓名进行成绩查询

(3) 输出查询结果，如果学生不存在则提示
