这是我自己写的一个码表计时器,运用jsp+servlet技术,用javascript,CSS3,HTML5和Ajax增强交互,开发环境为win7+MyEclipse10.5+jdk1.7+tomcat7,完成后的界面如下:
初始界面如下:
该界面中开始计时到分计的四个按钮为禁用状态
第二个界面是查看记录界面,从本地读取文件,呈现到网页中
正在计时,这时点击分计按钮,可以增加记录
此为将记录保存到本地
此为保存后查询,另外说明一下,清屏按钮能将当前所有状态还原为初始状态
项目缩略图如下:
servlet核心代码如下:
response.setContentType("text/html");
File file;
PrintStream ps;
PrintWriter out;
FileInputStream fis;
String text;
String oper="";
if(request.getParameter("operation")!=null){
oper=request.getParameter("operation");
if(oper.equals("write")){
out = response.getWriter();
text=request.getParameter("saveText");
if(text!=null&&!(text.equals(""))){
file=new File("E:\\yile\\webtest\\js\\log.txt");
if(!file.exists()){
file.createNewFile();
}
ps=new PrintStream(new FileOutputStream(file));
ps.write(text.getBytes());
out.print("success");
}else{
out.print("failure");
}
}else if(oper.equals("read")){
out=response.getWriter();
file=new File("E:\\yile\\webtest\\js\\log.txt");
fis=new FileInputStream(file);
byte[] b=new byte[1024];
StringBuffer sb=new StringBuffer();
if(fis.read(b)!=-1){
sb.append(new String(b));
b=new byte[1024];
}
out.print(sb.toString().trim());
}
}
CSS3设置圆角代码如下:

display:inline-block;
position:relative;
margin:10px;
padding:0 20px;
text-align:center;
text-decoration:none;

text-shadow:1px 1px 1px rgba(255,255,255,.22);

}
