身份證的驗證
function isIdCardNo(num)
{
if (isNaN(num)) {alert("輸入的不是數字！"); return false;}
var len = num.length, re;
if (len == 15)
re = new RegExp(/^(\d{6})()?(\d{2})(\d{2})(\d{2})(\d{3})$/);
else if (len == 18)
re = new RegExp(/^(\d{6})()?(\d{4})(\d{2})(\d{2})(\d{3})(\d)$/);
else {alert("輸入的數字位數不對！"); return false;}
var a = num.match(re);
if (a != null)
{
if (len==15)
{
var D = new Date("19"+a[3]+"/"+a[4]+"/"+a[5]);
var B = D.getYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5];
}
else
{
var D = new Date(a[3]+"/"+a[4]+"/"+a[5]);
var B = D.getFullYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5];
}
if (!B) {alert("輸入的身份證號 "+ a[0] +" 里出生日期不對！"); return false;}

雙擊鼠標滾動屏幕的代碼
var currentpos,timer;
function initialize()
{
timer=setInterval ("scrollwindow ()",30);
}
function sc()
{
clearInterval(timer);
}
function scrollwindow()
{
currentpos=document.body.scrollTop;
window.scroll(0,++currentpos);
if (currentpos !=document.body.scrollTop)
sc();
}
document.onmousedown=sc
document.ondblclick=initialize
調整window的滾動條大小
<body style="zoom:2">
<div style="zoom:0.5" >
</div>
</body>
實現啟動時加載類
第一步web.xml里添加
<listener>
??<listener-class>schoolcard.util.TimerListener</listener-class>
?</listener>
?
第2步創建監聽類
package schoolcard.util;
import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
public class TimerListener implements ServletContextListener {
?private ServletContext context = null;
?public void contextInitialized(ServletContextEvent arg0) {
??// TODO Auto-generated method stub
??System.out.println("服務器開始啟動.......................");
??//TimerUtil.runTimer();
??
?}
?public void contextDestroyed(ServletContextEvent arg0) {
??// TODO Auto-generated method stub?
?}
}
java里面定時器的制作
package schoolcard.util;
import java.util.Timer;
import schoolcard.dao.DAOFactory;
import schoolcard.datasource.PersistenceConstants;
public class TimerUtil {
?/**
? * @param args
? */
?public static void runTimer() {
??PersistenceConstants psc=new PersistenceConstants();
??String waitTime=psc.getProperty("repeatTime");
??int wt=Integer.parseInt(waitTime);
??System.out.println("wt"+waitTime);
??// TODO Auto-generated method stub
??try{
??? Timer timer= new Timer();
???timer.schedule(
???new java.util.TimerTask() {
????
???public void run()
???{
????//調用檢測發送進程
???System.out.println("XXXXXXXXXXXX**********************XXXXXXXXXXXX");
???DAOFactory df = DAOFactory.getDAOFactory();
???
???
???
???}
???}, 0, wt*1000);
???
??}catch(Exception e)
??{
???System.err.println("定時器出現問題");
???e.printStackTrace();
??}
?}
?public static void main(String[] args)
?{
??TimerUtil.runTimer();
?}
}
