Question

所以我正在努力创建自己的网站。我刚刚开始研究网站的关于我的部分，我想添加幻灯片来展示我的生活和兴趣的图片。我使用了书中的代码＆＃34; Jquery＆amp; Jon Duckett的Javascript＃34; 但由于某些原因，当我点击按钮切换到下一张幻灯片时，没有任何事情发生。

＆＃13; 我试图创建这个Content Panels- Responsive Slider

Answer 1

除非您想重新发明轮子本身，[参见下面的示例实现]您可以使用jquery ui carousel

http://code.runnable.com/WY_gouUfKGNOY4ET/output

或bootstrap创建轮播。
