Web程序设计实验报告PAGE1Web程序设计实验报告院别计算机与通信工程学院专业计算机科学与技术班级学号姓名成绩2013年12月27完成三个html页面，三个页面之间可以通过链接互相访问，自由的设置其中的控件，使用一个css表单来美化这三个页面。<!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML4.01Transitional//EN"><html><head><title>index.html</title> <metahttp-equiv="keywords"content="keyword1,keyword2,keyword3"><metahttp-equiv="description"content="thisismypage"><metahttp-equiv="content-type"content="text/html;charset=UTF-8"><!--<linkrel="stylesheet"type="text/css"href="./styles.css">--><linkrel="stylesheet"type="text/css"href="mycss.css"></head><body><h1>Sunset</h1><p><ahref="1.html">link1</a></br><ahref="2.html">link2</a></p></body></html><!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML4.01Transitional//EN"><html><head><title>1.html</title> <metahttp-equiv="keywords"content="keyword1,keyword2,keyword3"><metahttp-equiv="description"content="thisismypage"><metahttp-equiv="content-type"content="text/html;charset=UTF-8"><linkrel="stylesheet"type="text/css"href="mycss.css"><!--<linkrel="stylesheet"type="text/css"href="./styles.css">--></head><body><h1>ThisismyHTMLpage1.<br></h1></body></html>2.html<!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML4.01Transitional//EN"><html><head><title>2.html</title> <metahttp-equiv="keywords"content="keyword1,keyword2,keyword3"><metahttp-equiv="description"content="thisismypage"><metahttp-equiv="content-type"content="text/html;charset=UTF-8"><linkrel="stylesheet"type="text/css"href="mycss.css"><!--<linkrel="stylesheet"type="text/css"href="./styles.css">--></head><body><h1>ThisismyHTMLpage2.<br></h1></body></html>Mycss.css@CHARSET"UTF-8";h1{color:red;background-color:gray;text-align:left;font-size:58pt;}body{color:blue;background-image:url(Sunset.jpg);}

熟悉DOM的原理和使用【实验内容】在刚才建立的index.html页面添加一个删除按钮，做一个基于DOM的js函数，每次点击删除按钮就会将刚才生成的一个控件删除。【实验内容】将一个字符串使用doGet方法提交给Servlet，Servlet统计其中每个字母出现的次数，然后打印在页面上<%@pagelanguage="java"import="java.util.*"pageEncoding="UTF-8"%><%Stringpath=request.getContextPath();StringbasePath=request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPEHTMLPUBLIC"-//W3C//DTDHTML4.01Transitional//EN"><html><head><basehref="<%=basePath%>"><title>MyJSP'index.jsp'startingpage</title> <metahttp-equiv="pragma"content="no-cache"> <metahttp-equiv="cache-control"content="no-cache"> <metahttp-equiv="expires"content="0"> <metahttp-equiv="keywords"content="keyword1,keyword2,keyword3"> <metahttp-equiv="description"content="Thisismypage"> <!-- <linkrel="stylesheet"type="text/css"href="styles.css"> --></head><body>ThisismyJSPpage.<br><center><formmethod="get"action="servlet/login"><p>学号：<inputtype="TextField"name="id"value=""></p><p>姓名：<inputtype="TextField"name="name"value=""></p><p>字符串：<inputtype="TextField"name="str"value=""><p><inputtype="submit"name="Submit"value="签到"><inputtype="reset"value="重写"></form></center></body></html>【实验名称】使用servlet和JDBC访问数据库【实验内容】源代码：Index.jsp:
