Params
方法用於 頁面資源,它返回前置資料中定義的資源參數映射。此方法不適用於 全域 或 遠端 資源。
範例
假設你的內容結構如下:
content/
├── posts/
│ ├── cats/
│ │ ├── images/
│ │ │ └── a.jpg
│ │ └── index.md
│ └── _index.md
└── _index.md
並且在 cats.md
的前置資料中加入以下內容:
content/posts/cats.md
---
resources:
- params:
alt: Photograph of black cat
temperament: vicious
src: images/a.jpg
title: Felix the cat
title: Cats
---
+++
title = 'Cats'
[[resources]]
src = 'images/a.jpg'
title = 'Felix the cat'
[resources.params]
alt = 'Photograph of black cat'
temperament = 'vicious'
+++
{
"resources": [
{
"params": {
"alt": "Photograph of black cat",
"temperament": "vicious"
},
"src": "images/a.jpg",
"title": "Felix the cat"
}
],
"title": "Cats"
}
使用以下模板:
{{ with .Resources.Get "images/a.jpg" }}
<figure>
<img alt="{{ .Params.alt }}" src="{{ .RelPermalink }}" width="{{ .Width }}" height="{{ .Height }}">
<figcaption>{{ .Title }} is {{ .Params.temperament }}</figcaption>
</figure>
{{ end }}
Hugo 渲染後將顯示:
<figure>
<img alt="Photograph of black cat" src="/posts/post-1/images/a.jpg" width="600" height="400">
<figcaption>Felix the cat is vicious</figcaption>
</figure>
