問題解答

$(".tab").siblings().removeClass('xian');$(".tab").addClass('xian');

這里的代碼邏輯有問題，你先自己想想。

<script type="text/javascript">$(".main-lnav li").each(function(i){ $(this).click(function(){$(this).addClass('lgo').siblings().removeClass('lgo');$(".tab").removeClass('xian');$(".tab").eq(i).addClass('xian') })})</script>
