使用 JavaScript 处理重复的 HTML 数据好不好？
假设您有一个网站所有页面都相同的菜单。您应该使用客户端脚本还是服务器端脚本？
Let's say you have a menu that's the same for all pages of a website. Should you use client-side or server-side scripting for that?

我会在服务器端生成它并缓存它。为什么要让每个浏览器都做一些工作？
您可以为每个页面生成/输出相同的响应，而不是让 javascript 进行额外的调用或导致菜单仅在脚本运行完毕后才出现。
I would generate it on the server side and cache it. Why make every browser do some work?
You can generate/output it with the same response for each page instead of having javascript make extra calls or cause the menu to only appear after the script finished running.
如果是重复内容，我会通过
通过菜单，您还可以推迟脚本，以便它可以与用户访问网站要查看的主要内容并行下载。
If it's repetitive content, I would do client-side script loaded via
<script src=...>so that the repetitive content is separately cacheable to reduce the amount your users have to download. One caveat though, if your site has to work without javascript enabled, you obviously have to do it server-side.With menus, you can also make the script deferred, so that it can download in parallel to the main content that your users came to the site to see.
