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

  方法一:只在IE中有用

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

      方法二:不显示右键菜单
      <script language="javascript" for="document" event="oncontextmenu"> 
            window.event.returnValue=false;  
    </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>

var time = Math.floor(date / (1000 * 60 * 60 * 24));
  
if (time >= 0)
  document.write(
"现在离"+times+"还有: "+time +"")</script>

+ 'onClick="javascript:window.print()"></form>');
  }
  
// End -->
  </script>

12.单击按钮‘另存为’当前页

  onClick
="document.all.button.ExecWB(4,1)"
  <object id
="button"
  width
=0
  height
