在页面上单击随机 div 显示并使用 jquery 隐藏

Question

我在应用程序中有两个 div。 当单击导航链接和下一页完全加载时，我想要两个随机显示和隐藏那些 div。

下面的例子不包括多页，只包括单页。 所以想要从多个页面加载中随机显示和隐藏 div。

示例 - div 1 始终可见，因此如果用户单击任何导航链接并打开下一页，则第一个 div 隐藏第二个 div 将显示同样适用于其他导航链接单击。 随机切换两个div。

代码 ：

 $(".navbar .nav-link").click(function() { if ($('.card1:visible').length) { $('.card1').hide(); $('.card2').show(); } else { $('.card1').show(); } });

 .hide { display: none; } .Wrap .card img { height: 250px; }

这是一个工作演示，希望它能帮助我对您的代码进行了一些小的更改，现在它可以工作了。

 $(document).ready(function () { $('.card2').hide(); $(".navbar .nav-link").click(function () { if ($('.card1:visible').length) { $('.card2').show(); $('.card1').hide(); } else { $('.card1').show(); $('.card2').hide(); } }); });

 .hide { display:none; } .Wrap .card img { height: 250px; }
