如何做好幻燈片式的導航菜單，下面就是做導航菜單的代碼：
<style>
#linkView{
position:relative;
layer-background-color:black;
width:400;
height:12;
; font-family: "宋體"; font-size: 9pt}
#subtickertape{
background-color:black;
position:absolute;
border: 1px solid black;
width:400;
height:12;
; font-family: "宋體"; font-size: 9pt
}
.subtickertapefont{
font:bold 9pt "宋體";
text-decoration:none;
color:white;
}
.subtickertapefont a{
color:white;
text-decoration:none;
; font-family: "宋體"; font-size: 9pt}
</style>
</head>
<body bgcolor="#fef4d9" onload="if (document.all||document.layers) {regenerate2();update()}">
<div id="linkView">
<div id="subtickertape" class="subtickertapefont">初始化...</div>
</div>
<script language="JavaScript">
