51.向文件中写内容
<%@ page import="java.io.*" %>
<%
String str = "print me";
//always give the path from root. This way it almost always works.
String nameOfTextFile = "/usr/anil/imp.txt";
try
{
PrintWriter pw = new PrintWriter(new FileOutputStream(nameOfTextFile));
pw.println(str);
//clean up
pw.close();
}
catch(IOException e)
{
out.println(e.getMessage());
}
%>
52.先读文件再写文件
<%@ page language = "java" %>
<%@ page contentType = "text/html; charSet=gb2312" %>
<%@ page import ="java.util.*" %>
<%@ page import ="java.lang.*" %>
<%@ page import ="javax.servlet.*" %>
<%@ page import ="javax.servlet.jsp.*" %>
<%@ page import ="javax.servlet.http.*" %>
<%@ page import="java.io.*" %>
eryrytry
<%
int count=0;
FileInputStream fi =new FileInputStream ( "count.txt");
ObjectInputStream si= new ObjectInputStream (fi);
count =si.readInt();
count++;
out.print(count);
si.close();
FileOutputStream fo =new FileOutputStream ("count.txt");
ObjectOutputStream so= new ObjectOutputStream (fo);
so.writeInt(count);
so.close();
%>
53.直线型输入框
<INPUT name=Password size=10 type=password style="border-left-width: 0; border-right-width: 0;
border-top-width: 0; border-bottom-style: solid; border-bottom-width: 1; background-color: #9CEB9C">
54.可以将背景改为按钮性状，通过改变css改变属性
<td width="65" align="center" bgcolor="#E0E0E0" onmouseover=this.className='mouseoverbt';
onmouseout=this.className='mouseout';><a href="tm.asp?classid=76"><font
color="#000000">录音笔</font></a></td>
<style>
.mouseoverbt
{
background-image: url( http://www.yongle.com.cn/img/btbgw64h20y.gif);
background-repeat: no-repeat;
}
.mouseout
{
background-color: #E0E0E0;
}
</style>
55.同时按下CTRL和Q键
document.onkeydown=function()
{
if(event.ctrlKey&&event.keyCode==81)
{alert(1)}
}//

57.弹出窗口
方法一：<body onload="openwen()"> 浏览器读页面时弹出窗口；
方法二：<body onunload="openwen()"> 浏览器离开页面时弹出窗口；
方法三：用一个连接调用：<a href="#" onclick="openwin()">打开一个窗口</a>
注意：使用的"#"是虚连接。
方法四：用一个按钮调用：<input type="button" onclick="openwin()" value="打开窗口"> 何时装载script
58.动态改变字体的大小
function doZoom(size)
{
document.getElementById('zoom').style.fontSize=size+'px'
}
function aa()
{
var newWin=window.open(url);
newWin.document.form1.text1.value=value1;
}改变弹出窗口上域的属性
opener.document.form2.text2.value=value2;改变父窗口的域的值
59.判断是何种浏览器
var name = navigator.appName;
if (name == "Microsoft Internet Explorer")

61.复制内容到剪切板
function JM_cc(bb)
{
var ob=eval( "document.form1."+bb);
ob.select();
js=ob.createTextRange();

62.java中建立数据库连接取数据
public void init()
{
String url= "jdbc:odbc:javadata";
try
{
Class.forName( "sun.jdbc.odbc.JdbcOdbcDriver");
Connection con=DriverManager.getConnection(url, "sa","");//mssql database user SA and password
DatabaseMetaData dma=con.getMetaData();
System.out.println( "Connect to"+dma.getURL());
System.out.println( ";Driver "+dma.getDriverName());
System.out.println( ";Version "+dma.getDriverVersion());
System.out.println( "");
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery( "select * from company.dbo.TB_NAME where number=1");//Sql
rs.next();
String dispresult=rs.getString( "name");
System.out.println(dispresult);// Instead,you can display it in Paint() or use AWT etc.
rs.close();
stmt.close();
con.close();
}
catch(SQLException ex)
{
System.out.println( "!!!SQL Exception !!!");
while(ex!=null)
{
System.out.println( "SQLState:"+ex.getSQLState());
System.out.println( "Message:"+ex.getMessage());
System.out.println( "Vendor:"+ex.getErrorCode());
ex=ex.getNextException();
System.out.println( "");

function setbgcolor_onclick()
{
var color = showModalDialog( "/mailpage/compose/colorsel.html",0,"help=0");
if (color != null)
{
document.compose.bgcolor.value = color;
}
}//
70.截取小数点后两位
var a=3454545.4454545;
alert(a.toFixed(2));//
71.禁止选择页面上的文字来拷贝
<script>
function noEffect() {
with (event) {
returnValue = false;
cancelBubble = true;
}
return;
}
</script>
