在实现程序的修改模块时,要在页面端检查用户是否修改过数据,以便提醒用户及时保存修改后的数据。
实现要求:
判断用户是否修改了输入的内容,要能判断input中的checkbox,text,radio等,不知道会多少个input,也不知道input的ID和name,要在客户端判断是否修改,不能产
生提交。还要同时满足IE和firefox两种环境。也要支持master和content页的使用。
解决方案;
处理思路:在页面加载时记录所有的input的值或状态,如果要求在用户进行修改操作时立即调整控件状态,则在数据区div上的onclick和onkeypress事件里调用检查数据
是否改变的函数,并设置相应控件的状态(用ha_setch())。如果是在提交或用户手动控制检查过程时,则在相应的操作事件中调用检查数据是否改变(例在button的onclick
()中使用ha_checkin()控制提交)。
以下是实现代码
var ha_last=new Array;//定义一个全局的空对象,存放所有的初始值。
function ha_get()//读取初始值
{ var ha_input = document.getElementsByTagName("input");
for (var i=0;i<ha_input.length;i++)
{
if (ha_input[i].type=="password"){ ha_last.push(ha_input[i].value);}//根本页面需要设置type的值和对象属性
if (ha_input[i].type=="radio") {ha_last.push(ha_input[i].checked);}//要保证检查的范围是否准确
}
}
window.onload=ha_get;//绑定读取初始值的函数
function ha_checkin()//检查新的输入值和初始值是否相等。返回判断结果。true为没有发生修改,false为有修改。
{ var ha_now=new Array;
var ha_input = document.getElementsByTagName("input");
for (var i=0;i<ha_input.length;i++)
{
if (ha_input[i].type=="password"){ ha_now.push(ha_input[i].value);}//根本页面需要设置type的值和对象属性。
if (ha_input[i].type=="radio") {ha_now.push(ha_input[i].checked);}//也要保证和ha_get()中检查的标签相一致
}
if (ha_now.toString()==ha_last.toString())//没修改
{return true;}
else//有修改
{return false;}
}
function ha_setch(){//设置相应的控件状态
if (ha_checkin())//没有变化
//改变控件的显示和功能状态
else//有变化
//改变控件的显示和功能状态
}
做了适当的修改。最后在button里面onclick直接调用
var ha_last=new Array;//定义一个全局的空对象,存放所有的初始值。
function ha_get()//读取初始值
{
var ha_input = document.getElementsByTagName("input");
ha_last.push($("#select").val());//采用jquery获取select 选择的值
for (var i=0;i<ha_input.length;i++)
{
if (ha_input[i].type=="text"){ ha_last.push(ha_input[i].value);}//根本页面需要设置type的值和对象属性
}
}
window.onload=ha_get;//绑定读取初始值的函数
function ha_checkin(action)//检查新的输入值和初始值是否相等。返回判断结果。true为没有发生修改,false为有修改。
{
if(action=="update"){
var ha_now=new Array;
var ha_input = document.getElementsByTagName("input");
ha_now.push($("#select").val());
for (var i=0;i<ha_input.length;i++)
{
if (ha_input[i].type=="text"){ ha_now.push(ha_input[i].value);}//根本页面需要设置type的值和对象属性。
}
if (ha_now.toString()==ha_last.toString())//没修改
{
alert("没有修改");
return false;
}
else//有修改
{
// return true;
}
}
}

1.在当前类路径下新建一个properties文件;
编写DBconfig.properties
driver=com.microsoft.jdbc.sqlserver.SQLServerDriver
url=jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=school
user=sa
password=sa
2.新建工具类
package com.itcast.db;

import java.util.Properties;
public class ConnectionUtil {
public Connection openConnection() {
String driver = "";

//DriverManager获得连接
conn = DriverManager.getConnection(url, user, password);
return conn;

由于采用sql server2000作为数据库。用java进行jdbc连接时
出现Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
发现原来是少了sp4补丁。
先下载补丁文件
SQL2000-KB884525-SP4-x86-CHS.EXE
之后安装该文件,默认安装在c:/下
进入该文件夹,点击set up.bat 进行更新。
最后重新开启服务。就ok啦!
以前用myeclipse连接sql server 2005时,直接用的一个jdbcdriver.jar就ok了。但是目前为了需要
必须用sql server 2000,所以我才在网上找了找连接驱动。
SQLServer2000的JDBC驱动
转自 http://blog.csdn.net/javalf00/archive/2009/06/09/4254478.aspx
一、下载SQL SERVER2000的jdbc驱动程序。在微软站点就有这个驱动程序: Window操作系统
http://download.microsoft.com/download/3/0/f/30ff65d3-a84b-4b8a-a570-27366b2271d8/setup.exe Unix操作系统
Mssqlserver.tar http://download.microsoft.com/download/3/0/f/30ff65d3-a84b-4b8a-a570-27366b2271d8/mssqlserver.tar
二、安装JDBC 执行ms_jdbc_setup.exe可执行文件,一切只需要点击下一
步,至到出现finish按钮,完成安装。注: (1) ms_JDBC_setup默认安装路
径为:c:\Program Files\Microsoft SQL Server 2000 Driver for JDBC (2)此版
(Version 2.2.0022)本仅支持Microsoft SQL Server 2000 Driver for JDBC (3)安
装目录\lib\下的三个jar文件即是我们要的JDBC驱动核心 msbase.jar
mssqlserver.jar msutil.jar
三、将以上(3)中指的三个jar文件加入到环境变量中去 classpath:
d:\webserver\lib\msbase.jar;d:\webserver\lib\mssqlserver.jar;d:\webserver\lib\msutil.jar
注:也可以省事的将以上三个文件拷贝至你的jvm机所在的
JAVA_HOME\jre\lib\ext目录下,不过不建议这么做。 对于web项目,可
直接将以上三个jar包拷贝到WEB-INF下的lib文件夹下即可。
四、测试 jsp文件:
您的第一个字段内容为:
您的第二个字段内容为:
五、注意事项 1. 要保证你的Sql服务是启动状态 2. 在Sql 的管理器中能够
使用sa或其它用户正常登录;(有些人在安装sql时用了nt用户管理模式,
这里可能会有一定问题) 3. 第一次配置好环境变量最好能重启一下电脑
4. 注意JVM和DataBase的启动顺序:先启动DataBase,再启动JVM机。
注:在停止Web服务器后,再重启动,中间最好能有10秒以上的间隔。
5. 注意操作系统的网络连通性 A.启动了Tcp/IP服务 B.配置了相关IP地址,
有些人机器可能用的是自动分配IP或有配置IP时,但网络不通可能也找不
到IP 6. 有些机器在调试明最好能将(四)中的连接地址localhost改成数据
库服务器的IP,这也是要注意5的原因。
package zmsjdbc;
import java.sql.*;
public class sqlserver1 {
private String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=catv"; //catv是数据库!loacalhost可以用IP和主机
private String user="sa";
private String pwd="";
public Connection getcon() {
Connection con;
try { //加载驱动程序
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance(); //创建连接 con=DriverManager.getConnection(url,user,pwd);
return con;
} catch(ClassNotFoundException e) {
System.out.println("加载驱动程序出错");
} catch(SQLException e) {
System.out.println(e.getMessage());
} catch(Exception e) {
System.out.println("出现了好大的错误");
}
return null;
}
public ResultSet executeSql(String sqlstr) {
Connection conn; Statement stmt;
try { conn=getcon();
stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery(sqlstr);
return rs;
} catch(SQLException e) {
System.out.print("获取数据集时出现错误");
}
return null;
}
public static void main(String[] args) {
ResultSet rs1;
sqlserver1 sql1=new sqlserver1();
rs1=sql1.executeSql("select ui_id,ui_name from userinfo");
try {
while(rs1.next()) {
System.out.println(rs1.getString("ui_id")+" 姓名:"+rs1.getString("ui_name"));
}
} catch(Exception e)
{
System.out.println(e.getMessage());
}
} } /*
1、对于SQLSERVER 必须下载 SQLSERVER驱动 http://download.microsoft.com/download/3/0/f/30ff65d3-a84b-4b8a-a570-27366b2271d8/setup.exe 然后把 msbase.jar mssqlserver.jar msutil.jar 复制到 D:\JBuilder9\jdk1.4\jre\lib\ext,或者放在web项目的WEB-INF/lib下。
2:如果出现错误: java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket. 说明 SQLERVER 端口号 不对 》》》更改端口号:SQLSERVER->属性-常规-网络配置-常规-TCP/IP-属性--更改端口号有个命令可以用: cmd-> netstat -a 例如:String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=zmstv"; 说明你使用的是1433 在CMD 下 输入 netstat -a -n 应该看不到:TCP 127.0.0.1:1433 0.0.0.0:0 LISTENING 如果安装 sqlserver 2000 出现 报错 "以前的某个程序安装已在安装计算机上创建挂起的文件操作。。。。" 打开注册表编辑器,在 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager中找到PendingFileRenameOperations项目,并删除它。这样就可以清除安装暂挂项目。
在J2ME程序开发过程中,为了一定的需要,经常需要来获得用户的手机号码,但是这个功能却在标准的J2ME类库中没有提供。
在使用中国移动的CMWAP方式连接网络时,中国移动会将用户的手机号码放在一个名称为x-up-calling-line-id的头信息中,可以通过读取该头信息,获得用户的手机号码,具体代码如下:
String usermphone = http.getHeader("x-up-calling-line-id");
伪手机号,用户在移动梦网的ID:
String usermphone = http.getHeader("MISC_MID");
其中http是HttpConnction类型的对象。
[color=Green]注意:必须要是CNWAP联网才行。 [/color]
原来获取用户手机号码很简单,关键是通信营运商给不给你送。如果给你送的话,手机号码是在Http请求头里获取,通常在x-up-calling-line-id项里,如果通过此项得不到的话。可采用循环读出所有的Http头里的信息,号码在哪一个头里就一目了然了。
String userPhone = request.getHeader("x-up-calling-line-id");一般通过这句就能获取到手机号码。
如果号码不在上面这条请求头里,采用下面方法读取看号码在哪一条请求头里。
Enumeration headers = request.getHeaderNames() ;
while(headers.hasMoreElements())
{
String head = (String)headers.nextElement();
out.println(head+":"+request.getHeader(head));
}
这样就可以将所有的信息打印出来,看到号码的位置了。注意获取号码的前提是跟营运商有合作或者跟他们申请。同意给你送,否则程序实现了也没有用。
