## Introduction
|
|
|
|
{{% include "functions/_common/go-html-template-package.md" %}}
|
|
|
|
## Usage
|
|
|
|
Use the `safe.HTMLAttr` function to encapsulate an HTML attribute from a trusted source.
|
|
|
|
Use of this type presents a security risk: the encapsulated content should come from a trusted source, as it will be included verbatim in the template output.
|
|
|
|
See the [Go documentation] for details.
|

|
|
|
|
## Example
|
|
|
|
Without a safe declaration:
|
|
|
|
```go-html-template
|
|
{{ with .Date }}
|
|
{{ $humanDate := time.Format "2 Jan 2006" . }}
|
|
{{ $machineDate := time.Format "2006-01-02T15:04:05-07:00" . }}
|
|
<time datetime="{{ $machineDate }}">{{ $humanDate }}</time>
|
|
{{ end }}
|
|
```
|
|
|
|
Hugo renders the above to:
|
|
|
|
```html
|
|
<time datetime="2024-05-26T07:19:55+02:00">26 May 2024</time>
|
|
```
|
|
|
|
To declare the key-value pair as safe:
|
|
|
|
```go-html-template
|
|
{{ with .Date }}
|
|
{{ $humanDate := time.Format "2 Jan 2006" . }}
|
|
{{ $machineDate := time.Format "2006-01-02T15:04:05-07:00" . }}
|
|
<time {{ printf "datetime=%q" $machineDate | safeHTMLAttr }}>{{ $humanDate }}</time>
|
|
{{ end }}
|
|
```
|
|
|
|
Hugo renders the above to:
|
|
|
|
```html
|
|
<time datetime="2024-05-26T07:19:55+02:00">26 May 2024</time>
|
|
```
