</ul>
</li>
<script>
function showMenu(s){
if(s == 1){
document.getElementById("ul1").style.display="block";
document.getElementById("ul2").style.display="none";
}else if(s == 2){
document.getElementById("ul2").style.display="block";
document.getElementById("ul1").style.display="none";
}
}
</script>
这样就行了

、。。。不止二个菜单的，没说清楚，对不起饿。。。
追答
数量是不定的还是有定值?如果数量是定值的话,就在ul标签上加ID,然后在showMenu方法里面往上叠加就行
