网页常用JAVAscript

1.让文字不停地滚动

  <MARQUEE>滚动文字<
/MARQUEE>

2.记录并显示网页的最后修改时间

  <script language
=JAVAscript>
  document.write(
"最后更新时间: " + document.lastModified + "")
  <
/script>

3.关闭当前窗口

  <a href
="/"onClick="JAVAscript:window.close();return false;">关闭窗口</a>

4.5秒后关闭当前页

  <script language
="JAVAscript"
  <
!--
  setTimeout(
'window.close();',5000);
  
--
  <
/script>

5.2秒后载入指定网页

  <head>
  <meta http
-equiv="refresh" content="2;URL=http://你的网址"
  <
/head>

6.添加到收藏夹

  <script Language
="JAVAscript"
  
function bookmarkit()
  {
  window.external.addFavorite(
'http://你的网址','你的网站名称')
  }
  
if (document.all)document.write('<a href="#" onClick="bookmarkit()">加入收藏夹</a>')
  <
/script>

7.让超链接不显示下划线

  <style type
="text/css"
  <
!-
  a:link{text
-decoration:none}
  a:hover{text
-decoration:none}
  a:visited{text
-decoration:none}
  
-
  <
/style>

8.禁止鼠标右键的动作

  <script Language
= "JAVAscript"
  
function click() { if (event.button==2||event.button==3)
  {
  alert(
'禁止鼠标右键');
  }
  document.onmousedown
=click // -->
  </script>

9.设置该页为首页

  <body bgcolor
="#FFFFFF" text="#000000"
  <
!-- 网址:http://你的网址-->
  <a class="chlnk" style="cursor:hand" HREF
  onClick
="this.style.behavior='url(#default#homepage)';
  this.setHomePage('你的网站名称);
"><font color="000000" size="2" face="宋体">设为首页</font></a>
  <
/body>

  <script Language
="JAVAscript"
  
var timedate= new Date("December 25,2003");
  
var times="圣诞节";
  
var now = new Date();
  
var date = timedate.getTime() - now.getTime();
  
var time = Math.floor(date / (1000 * 60 * 60 * 24));
  
if (time >= 0)
  document.write(
"现在离"+times+"还有: "+time +"")</script>

11.单击按钮打印出当前页

  <script Language
="JAVAscript"
  <
!-- Begin
  
if (window.print) {
  document.write(
'<form>'
  
+ '<input type=button name=print value="打印本页" '
  
+ 'onClick="JAVAscript:window.print()"></form>');
  }
  
// End -->
  </script>

12.单击按钮‘另存为’当前页

  <input type
="button" name="Button" value="保存本页"
  onClick
="document.all.button.ExecWB(4,1)"
  <object id
="button"
  width
=0
  height
=0
  classid
="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"
  <embed width
="0" height="0"></embed>
  </object>

13.显示系统当前日期

  <script language
=JAVAscript>
  today
=new Date();
  
function date(){
  
this.length=date.arguments.length
  
for(var i=0;i<this.length;i++)
  
this[i+1]=date.arguments }
  
var d=new date("星期日","星期一","星期二","星期三","星期四","星期五","星期六");
  document.write(
  
"<font color=##000000 style='font-size:9pt;font-family: 宋体'> ",

if (document.all)
  {
    document.write(
'<img id=mdiv src="'+document.all.reflect.src+'"
    style="filter:wave(strength=3,freq=3,phase=0,lightstrength=30) blur() flipv()">

  temploc
=thelocation
  
if
  (
!(window.resizeTo&&document.all)&&!(window.resizeTo&&document.getElementById))
  {
    window.open(thelocation)
    
return

  windowsize
=window.open("","","scrollbars")
  windowsize.moveTo(
0,0)
  windowsize.resizeTo(
100,100)
  tenumxt()
  }
  
function tenumxt(){
  
if (Windowsheight>=screen.availHeight-3)
    numx
=0
  windowsize.resizeBy(
5,numx)
  Windowsheight
+=5
  Windowswidth
+=5
  
if (Windowswidth>=screen.width-5)
  {
    windowsize.location
=temploc
    Windowsheight
=100
    Windowswidth
