I want to add a random article picker to my blog as another way to discover past posts, aside from categories and tags on the right side and making it easier on mobile.
I couldn’t find a simple enough solution that suits my needs after brief Googling. The options I found were either to randomize at build time, which means the article doesn’t change with each click or refresh, or to generate a JSON index, which I had trouble with probably because my lack of understanding of Hugo.
I thought such a simple feature should be achievable with just JS + HTML, so I decided to write my own. Performance shouldn’t be an issue for a blog with a few tens to thousands of articles. Here’s a solution I came up with for reference.
我想给自己的博客加一个随机文章入口，作为页面右边的分类和 tag 之外的另一个发掘文章入口，移动端也更容易。在网上一搜，Google 第一页没有看到太显眼的简单适合我博客的答案：要么是最简单的 build time randomize，不能每次点击/刷新都出新文章；要么要生成 json 索引，对 hugo 语言和 config 不是很熟悉的我折腾了一下没搞出来，遂放弃。
想说这么简单个功能不至于不能纯拿 JS + html 写吧，博客少则几十多则几千的随机数性能应该也不成问题，随自己折腾出来个方案供大家参考。
