PHP简单的滑动菜单制作
本例使用无线表格，以类的书写方式表述。
本代码可自由扩散。
--->
<style>
table {font-size = 9pt}
td {height = 20px}
</style>
<body>
<span id="menus"></span>
<span id="view"></span>
</body>
<script for=pad event=onclick>
// 大类节点点击响应
for(var i=1;i<this.parentElement.rows.length;i+=2)
this.parentElement.rows[i].style.display = "none";
this.parentElement.rows[this.rowIndex+1].style.display=´block´;
view.innerHTML = this.v1 +":"+ this.v2; // 根据大小类自行构造相应动作
</script>
<script for=bar event=onclick>
// 小类节点点击响应
view.innerHTML = this.v1 +":"+ this.v2; // 根据大小类自行构造相应动作
</script>
