关于go:Golang-语雀内容系统5-详情页Toc导航栏

实现性能

• 减少文章详情页Toc文章目录

实现思路

对文章内容提取 h1, h2, h3, h4, h5 标签与锚，这里咱们将采纳到第三方包

• github.com/PuerkitoBio/goquery

// handler/post.gohtml = `<h1 id="H55oy1">语雀文章内容</h1><h2 id="H55oy2">语雀文章内容</h2><h3 id="H55oy3">语雀文章内容</h3><h4 id="H55oy4">语雀文章内容</h4><h5 id="H55oy5">语雀文章内容</h5>`doc, _ := goquery.NewDocumentFromReader(strings.NewReader(html))var navs []*Navdoc.Find("h1, h2, h3, h4, h5").Each(func(i int, s *goquery.Selection) {    // ...    navs = append(navs, &Nav{        ID: "",        Title: "",        Level: "",    })})type Nav struct {    ID string    Title string    Level int}
