{{ range .Ancestors }}
<a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
{{ end }}在 2023 年 11 月拍卖页面上,Hugo 渲染:
<a href="/auctions/2023-11/">Auctions in November 2023</a>
<a href="/auctions/">Auctions</a>
<a href="/">Home</a>在上面的示例中,注意 Hugo 从最近到最远排序祖先。这使得面包屑导航变得简单:
<nav aria-label="breadcrumb" class="breadcrumb">
<ol>
{{ range .Ancestors.Reverse }}
<li>
<a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
</li>
{{ end }}
<li class="active">
<a aria-current="page" href="{{ .RelPermalink }}">{{ .LinkTitle }}</a>
</li>
</ol>
</nav>使用一些 CSS,上面的代码渲染如下,每个面包屑链接到其页面:
Home > Auctions > Auctions in November 2023 > Auction 1
