Question

我在github.com上复制别人work时遇到很大困难

我正在尝试做什么

我正在尝试为我的网站构建（复制）自定义滚动条。

什么无效

好的，所以我正确地下载了文件夹，我创建了一个index.html并将所有文件链接到它。因此，当我在浏览器（chrome或firefox）上运行index.html时，条形图不会上下滑动，它处于静止位置;但内容仍在滚动。此外，我无法用光标抓住栏以滚动文本。我是一个表面专业4，128gb $ 800的价值，但得到它200美元，所以我只能使用触摸屏滚动。

我想要什么

我只想要链接中的自定义栏，但实际上效果很好。如果您有更好的解决方案，那么他们展示的那个请告诉我！

Here is there example!

      <p>But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?</p>

Answer 1

您所做的只是复制相关网站的整个HTML输出。

如果您想使用给定的库，您必须在README部分中执行他们所说的内容：

https://github.com/buzinas/simple-scrollbar#manual-binding

要像这样使用它，您需要将脚本添加到代码库中。这就是关于两个javascript文件的问题出现的地方：有两个给定的javascript文件，一个以WITH .min.js结尾，另一个WITHOUT .min.js.。 min指的是minified，因此它不会占用太多空间。

请不要在Instagram上分享视频。非常不专业。

Answer 2

我认为你应该从这个案例的基础开始，然后在你自己的网站上复制代码。

很棒的教程，很好的例子可以在这里找到： https://www.w3schools.com/jS/default.asp
