下面是我写的ｊｑｕｅｒｙ哪里出错了？求指点
$(".main-lnav li").click(function(e){
$(this).siblings().removeClass('lgo');
$(this).addClass('lgo');
e.stopPropagation();
//table切换
$(".tab").siblings().removeClass('xian');
$(".tab").addClass('xian');
e.stopPropagation();
});
$(".tab").siblings().removeClass('xian'); $(".tab").addClass('xian');这里的代码逻辑有问题，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>
