文章类别：Javascript | 发表日期:2010-5-31 14:37:40

一、如果文字过长,则将过长的部分变成省略号显示
<DIV STYLE="width: 120px; height: 50px; border: 1px solid blue;
overflow: hidden; text-overflow:ellipsis">
<NOBR>就是比如有一行文字，很长，表格内一行显示不下.</NOBR>
</DIV>

二、滚动的图片
<script language="javascript">
imgArr=new Array()
imgArr[0]="<a href=http://www.wawaqin.com/ onmouseMove='javascript:outHover=true' onMouseover='javascript:outHover=true' onMouseout='javascript:outHover=false;mvStart()'><img src=http://www.wawaqin.com/images/wawaqin_logo.gif border=0></a>"

</script>
<BODY onload=javascript:mvStart()>
<SCRIPT language=javascript>writeDivs();initDivPlace();</SCRIPT>

三、接收键盘指令的脚本
按A就会跳转到娃娃亲的网页,请按A
<SCRIPT language="JavaScript">
<!--
var hotkey=97
var destination="http://www.wawaqin.com"
if (document.layers)
document.captureEvents(Event.KEYPRESS)
function backhome(e){
if (document.layers){
if (e.which==hotkey)
window.location=destination
}
else if (document.all){
if (event.keyCode==hotkey)
window.location=destination
}
}
document.onkeypress=backhome
onkeydown="javascript:onenter();"
function onenter(){
if(event.keyCode==13){
alert("回车");
}
}
</SCRIPT>

七、DIV的透明层实现

                              </tr>
                              <tr>

            <td height="20" bgcolor="#f5f5f5" class="12">地址</td>
                              </tr>
                              <tr>

            <td height="20" bgcolor="#f5f5f5" class="12">邮编</td>
                              </tr>
                            </table>
              </div>

八、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>
<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>

=========================================
再写一个JSP页面: buildhtml.jsp

<%@ 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());
}
