전에 것보다 간단한 탭메뉴

<script language="javascript" type="text/javascript">
function tab(num) {
 var tabB = "tab"+num;
 for(i=1;i<3;i++){
  var tabnum = "tab"+i;
  document.getElementById(tabnum).style.display="none";
 }
 document.getElementById(tabB).style.display="block";
}
</script>

<div id="tab1" style="display:block;">
 <a href="javascript:tab(1)">asdasd</a>
 <a href="javascript:tab(2)">asdasd</a>asdasdasdasd
</div>

<div id="tab2" style="display:none;">
 <a href="javascript:tab(1)">asdasd</a>
 <a href="javascript:tab(2)">asdasd</a>dsssssssss
</div>

 

i로 갯수를 조절하자
