js實作無限級樹狀導航列表效果程式碼_javascript技巧

本文實例講述了js實現無限級樹形導航列表效果代碼。分享給大家供大家參考。具體如下：

這是一款js實現無限級樹形下拉導航選單，簡潔實用，用到一個已封裝好的JS類，有用的大家借鏡一下。

運作效果截圖如下：

線上示範網址如下：

具體程式碼如下：

<style type="text/css"> 
 *{ margin:0; padding:0; list-style:none;} 
 body { margin:20px;} 
 h2 { font-family:"黑体"; font-size:24px; text-align:center; line-height:32px;} 
 h5 { font-size:12px; text-align:center; font-weight:normal; color:#666; line-height:28px;} 
 #nav a { text-decoration:underline;color:#06c; font-size:14px; line-height:24px;} 
 #nav ul{ margin-bottom:5px;} 
 #nav strong{ color:#696;} 
 #nav.dyn li ul{ display:none;} 
 #nav.dyn li ul.show{ display:block;} 
 #nav.dyn li{ padding-left:15px;} 
 #nav.dyn li.parent{ background:url(images/user_23.gif) 5px 10px no-repeat;} 
 #nav.dyn li.open{ background:url(images/user_23.gif) 5px -34px no-repeat;}
