safe.HTMLAttr	Declares the given key-value pair as a safe HTML attribute.			aliases related returnType signatures safeHTMLAttr functions/safe/CSS functions/safe/HTML functions/safe/JS functions/safe/JSStr functions/safe/URL template.HTMLAttr safe.HTMLAttr INPUT	true	/functions/safehtmlattr

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:

{{ 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:

<time datetime="2024-05-26T07:19:55&#43;02:00">26 May 2024</time>

To declare the key-value pair as safe:

{{ 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:

<time datetime="2024-05-26T07:19:55+02:00">26 May 2024</time>
