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:
#begin,#stop,#reBegin,#refresh,#clearScreen{ display:inline-block; position:relative; margin:10px; padding:0 20px; text-align:center; text-decoration:none; font:bold 12px/25px Arial,sans-serif; text-shadow:1px 1px 1px rgba(255,255,255,.22); -webkit-border-radius:30px; -moz-border-radius:30px; border-radius:30px; -webkit-box-shadow:1px 1px 1px rgba(0,0,0,.29),inset 1px 1px 1px rgba(255,255,255,.44); -moz-box-shadow:1px 1px 1px rgba(0,0,0,.29),inset 1px 1px 1px rgba(255,255,255,.44); box-shadow:1px 1px 1px rgba(0,0,0,.29),inset 1px 1px 1px rgba(255,255,255,.44); -webkit-transition:all 0.15s ease; -moz-transition:all 0.15s ease; -o-transition:all 0.15s ease; -ms-transition:all 0.15s ease; transition:all 0.15s ease; color:#515151; background:#d3d3d3;/*old browsers */ background:-moz-linear-gradient(top,#d3d3d3 0%,#8a8a8a 100%);/*FF3.6+ */ background:-webkit-gradient(linear,left top,left bottom,color-stop(0%,#d3d3d3),color-stop(100%,#8a8a8a));/*chrome,Safari4+ */ background:-webkit-linear-gradient(top,#d3d3d3 0%,#8a8a8a 100%);/*chrome10+,safari5.1+ */ background:-o-linear-gradient(top,#d3d3d3 0%,#8a8a8a 100%);/*opera 11.10+ */ background:-ms-linear-gradient(top,#d3d3d3 0%,#8a8a8a 100%);/*ie10+ */ background:linear-gradient(top,#d3d3d3 0%,#8a8a8a 100%);/*w3c */ }
