我试图让一个输入复选框触发问题的b版本是否出现。如果他们选择永不消失，它就会消失。我正在使用两个类来收听。单击.showb时，找到下一个.bques并显示它。单击.hidb时，找到下一个.bques并将其隐藏。看起来很简单，但是我不知道为什么它不起作用。请帮忙。
使用$（“ p”）。next（“。bques”）。show（“ fast”）;而不是$（this）.next（“。bques”）。show（“ fast”）;在页面上显示所有b问题。我也尝试过.nextAll，但是没有运气。为什么这不起作用？这是孩子的兄弟姐妹问题吗？

最佳答案
改成
$().ready(function() {
$(".showb").click(function () { $(this).parent().next(".bques").show("fast"); });
$(".hidb").click(function () { $(this).parent().next(".bques").hide("fast"); });
});
