我有一个框，其中的文本向上滚动，就像旧的已知选取框标签一样。
我正在使用我在这个网站上找到的 jquery 滚动框:
http://wmh.github.io/jquery-scrollbox/
现在，在我的 css 文件中，我想用类替换 ul 和 il 标签，比如:.list_wrapper 将代替 ul，.list 将代替 li，到目前为止一切顺利......
修改css后，scroller停止工作，我发现我也需要修改“jquery.scrollbox.js”文件，但我对js的了解很基础。

这是 js 文件(我认为这与“('ul:first-child')和('li:first-child')有关):

谢谢!
最佳答案
打开 jquery-scrollbox.js 并尝试手动(不是自动)更改 div 标签上的所有 ul&li 标签
关于javascript - 用类 'ul:first-child' 替换选择器 '.list_wrapper:first-child'，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18510726/
