1 绪论 ...................................................................................................................................... 1 1.1开发背景 ............................................................................................................................ 1 实验教学是学生技能培养的重要环节之一，学生实验报告的质量在一定程度上反映了实验教学的质量，实验报告管理水平也反映了实验教学管理水平。目前，大部分学校所提交的实验报告大多还停留在以纸为介质的方式上，这将严重制约着实验教学的开展。首先，很多课程的实验结果在纸质实验报告中不能表现或不能完全表现，其次纸质实验报告的批改和分析也是实验授课老师的一个很重负担，如何提高学生实验报告的表象能力，提高教师批改实验报告的效率并及时发现和纠正实验报告中存在的问题是许多课程实验授课教师所面对的一个难题。 ..................................................................................... 1

Css的学习：虽然说在标签中也可以定义样式，但是这么做看起来不是那么明智，我在学CSS时还是比较努力的，所有的样式效果都测试过，并且写了相应的案例，只是过了不到3个月就忘了一大半，很多时候都是查文档才能写出来的，虽然CSS对于我们来说不必要非常精通，但是我觉得掌握的东西越多，以后的工作就越轻松，所以在考试结束后也会去看看前面的笔记和案例。 Javascript：js 我认为是最重要的，甚至于超过servlet，jsp，在上课期间，讲的内容还是比较少的，就javascript中创建对象来说吧，应该只讲过3中方法，虽然在一般的情况下是用不上的，但是我觉得还是有必要学习的，这样有助于看懂别人写的框架，在javascript这部分学习中讲的最多的还是dom操作，不过我觉得用dom操作太繁琐了，写的代码太多，而且效率看起来也不高，后面就是讲的事件，事件也算是简单的，只是对触发的事件进行相应的响应。除了这些就是javascript流程控制，对象一些基本语法，这些和java类似，所以在上课时没有讲得太多。 Servlet：我觉得是比较简单的，可能是因为它是java代码，容易理解。首先讲的是开发环境的配置，安装tomcat，了解tomcat下的目录，以及web工程下的目录。后来是讲了servlet的访问方式，post和get的区别，处理中文乱码是servlet中一个重要的知识点，几乎每个项目都会遇到这个问题。主要乱码有get，post乱码，是通过设置request或者response的编码方式来实现的。Servlet间的跳转方式有重定向和转发，对于重定向和转发的区别，现在理解的很透彻了，重定向是不能获取request中参数，是客户端的两次请求，而转发是服务器内部跳转，不过，两种在设置过滤器的情况下，都要通过过滤器才能跳转。Servlet的生命周期是笔试的必考题，其实这是很简单的，只需要理解，没必要死记硬背的，session算是重要的知识点，很多数据都是存储在内存中，如购物车，用户信息等，还可以对session设置生存时间。说到session就必须说说四种会话跟踪技术，cookie，URL重写，表单域隐藏和session。 JSP：JSP实际上和servlet是一样的，只不过两者侧重点不同，JSP的内置对象和作用域大致是一样的，JSP中还有动作，常用的有操作JavaBean的动作，页面跳转的动作，以及包含的动作。这里重点提到两种包含的区别。在JSP还讲过jstl和EL表达式，都是基础的应用，不过写自定义的标签还是要有一定的java基础的，我开始不太理解标签的解析过程，后来看了几个例子，发现自定义的已不是那么难。 jQuery：jQuery可以说是中级部分学的最好的，主要是它方便了，特别是选择器，而且避免了一些浏览器的差异，所以在学习jQuery后，就再也不想用javascript来获取元素了。不仅如此，jQuery中封装的Ajax操作也是非常简单，不需要自己封装一个类，$.get和$.post 能够省去很多麻烦，jQuery的监听事件也是很简单，不需要在标签中添加对应事件，可以动态的绑定事件。还有就是dom操作更是方便。我在学习完Ajax，json后就发现，即使是没有JSP，也能做出一个动态页面出来，只是会存在效率问题。 37 总结：虽然说这上面的知识大部分都掌握了，但是能否灵活运用才是重点，所以在今后的学习中多思考问题是否有多种解决方法。 37 参考文献 [1]周恒，王殊宇.JSP项目开发全程实录[M].北京：清华大学出版社, 2008． [2]张桂珠，刘丽，陈爱国.Java面向对象程序设计[M].北京：北京邮电大学出版社, 2007． [3]孙卫琴.
