*****[第2页目录]*****
十一 超级强大的表单验证-----推荐
十二 漂亮的脚本日历
十三 进入,退出页面的各种效果!
十四 很酷的效果,表格被选中回变颜色
十五 弹出提示的效果
十六 图片之间的切换
十七 DIV_圆边圆角的实现
十八 跳动的菜单
十九 通过页面抓取照片
二十 客户端静态页面玩分页

十 JSP页面自动生成html页面/或任何格式页面:

先建立一个模本页面:template.htm


[html]<html>
<head>
<title>###title###</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<LINK href="../css.css" rel=stylesheet type=text/css>
</head>

<body>
<table width="500" border="0" align="center" cellpadding="0" cellspacing="2">
<tr>
<td align="center">###title###</td>
</tr>
<tr>
<td align="center">作者:###author###  </td>
</tr>
<tr>
<td>###content###
</td>

</tr>

</table>
</body>
</html>[/html]


再写一个JSP页面: buildhtml.jsp:

[html]<%@ page contentType="text/html; charset=gb2312" import="java.util.*,java.io.*"%>
<%
try{
String title="李鹏的jsp生成静态html文件";
String content="小样,还搞不定你?";
String editer="hpsoft";
String filePath = "";
filePath = request.getRealPath("/")+"template.htm";
out.print(filePath);
String templateContent="";
FileInputStream fileinputstream = new FileInputStream(filePath);//读取模块文件
int lenght = fileinputstream.available();
byte bytes[] = new byte[lenght];
fileinputstream.read(bytes);
fileinputstream.close();
templateContent = new String(bytes);
out.print(templateContent);
templateContent=templateContent.replaceAll("###title###",title);
templateContent=templateContent.replaceAll("###content###",content);
templateContent=templateContent.replaceAll("###author###",editer);//替换掉模块中相应的地方
out.print(templateContent);
// 根据时间得文件名
Calendar calendar = Calendar.getInstance();
String fileame = String.valueOf(calendar.getTimeInMillis()) +".html";
fileame = request.getRealPath("/")+fileame;//生成的html文件保存路径
FileOutputStream fileoutputstream = new FileOutputStream(fileame);//建立文件输出流
out.print("文件输出路径:<br>");
out.print(fileame);
byte tag_bytes[] = templateContent.getBytes();
fileoutputstream.write(tag_bytes);
fileoutputstream.close();
}
catch(Exception e){
out.print(e.toString());
}

%>[/html]


十一 超级强大的表单验证:

[html]<title>表单验证类 Validator v1.01</title>
<style>
body,td{font:normal 12px Verdana;color:#333333}
input,textarea,select,td{font:normal 12px Verdana;color:#333333;border:1px solid #999999;background:#ffffff}
