一个js的树形结构脚本

    下面是 点击按钮的同时在parentframe中，装载两个页面
<HTML><HEAD><title>Frames</title></HEAD>    <FRAMESET COLS="295,*">   <FRAMESET ROWS="100%,*">     <FRAME SRC="loadtwo.html" NAME="fr1">       </FRAMESET>   <FRAMESET ROWS="75%,25%">     <FRAME SRC="cell.html" NAME="fr2">     <FRAME SRC="cell.html" NAME="fr3">       </FRAMESET> </FRAMESET> </HTML>
第 一 个 frame 会 载 入 loadtwo.html 并 产 生 一 个 按 钮 : 
loadtwo.html
<HTML><HEAD><script language="JavaScript"><!-- Hiding  function loadtwo(page2, page3) {     parent.fr2.location.href=page2;     parent.fr3.location.href=page3;}// --></script></HEAD><BODY><FORM NAME="buttons">     <INPUT TYPE="button" VALUE="同 时 载 入 两 份 文 件" onClick="loadtwo('frtest1.html',     'frtest2.html')"></FORM></BODY></HTML>
   动态改变按钮上的文字
<html>
 <body>
 <input type=button name =b1 value="按钮1" onclick="abc()">
 <input type=button name =b2 value="按钮2" >
 <input type=button name =b3 value="按钮3">
 </body>
</html>
<script language=javascript>
function abc()
{
 for(i=1;i<=3;i++)
 {
  document.all("b"+i).value=i;
 }
}
</script>
图片移动标签：
scrollAmount=2   数字越大，速度越快
direction=up  移动的方向  可以变换英文“下”“左”“右”
height=200   为移动的高度  
<MARQUEE scrollAmount=2 direction=up height=200>
