代码作用:
$(function() { $(".tablea").find(".box:first").show(); //为每个box的第一个元素显示 $("#oranger a").on("mouseover", function() { //给a标签添加事件 var index = $(this).index(); //获取当前a标签的个数 $(this).parent().next().find(".box").hide().eq(index).show(); //返回上一层,在下面查找css名为box隐藏,然后选中的显示 $(this).addclass("hover").siblings().removeclass("hover"); //a标签显示,同辈元素隐藏 }) })
