经过若干时间的奋战,终于完成了web版四则运算程序。团队成员:井小普、张贺。
设计思想:
在之前的程序基础上两人结合开发web系统。
首先,进行登录注册界面的编写,不同用户,对应不同的错题库,答题记录;
然后进入主页,主页中在登录成功后左上角会显示“您好!用户名”,并有开始答题,查看历史错题和注销三个按钮。开始答题按钮可以供用户选择出题的条件生成题目,查看历史错题会调出数据库中历史的错题,注销会注销当前用户,返回登录界面。
之后便是根据用户设置的不同数目的题目,自动设置倒计时,倒计时时间到后,自动提交试卷,之后显示用户答题结果,如果错误会显示正确结果,错误的题目归到错题库中。
最后对页面使用了Javabean、servlet、ajax、jQuery,并对页面进行了美化。这次程序的完成没有用模板,的确页面可能不是特别美观,但我们期待有一天我们依旧能够不用模版达到非常酷炫、美观的效果。
工程文件夹截图如上;
在此只粘贴部分网页代码:

截图如下:
点击“登录”
登录:
开始做题:
交卷:
查看错题库:
点击注销会出现“两秒后进入登录界面!”。。。。。
我相信,通过这次实践自己付出的努力亦或是学到的东西别人是看不到的,所以不论结果如何,也不管别人怎么看,我们问心无愧就好!
