| hexo.extend.generator.register('random', function (locals) {
const config = hexo.config.random || {}
const posts = []
for (const post of locals.posts.data) {
if (post.random !== false) posts.push(post.path)
}
return {
path: config.path || 'random/index.html',
data: `<html><head><script>var posts=${JSON.stringify(posts)};window.open('/'+posts[Math.floor(Math.random() * posts.length)],"_self")</script></head></html>`
}
})

在你想要的位置引用/random/index.html即可

const posts = []
hexo.locals.get('posts').map(function (post) {
if (post.random !== false) posts.push(post.path)
})
data += `<script>var posts=${JSON.stringify(posts)};function toRandomPost(){ window.pjax ? pjax.loadUrl('/'+posts[Math.floor(Math.random()*posts.length)]) : window.open('/'+posts[Math.floor(Math.random()*posts.length)], "_self"); };</script>`
return data
})

正常调用toRandomPost()函数即可。
