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)}
}//
56.以下是一个完整的显示hint的代码，其思想是当鼠标停留是将div中的内容显示在鼠标出，当鼠标移出后在将该div隐
藏掉
