safe.HTMLAttr

Syntax

safe.HTMLAttr INPUT

Returns

template.HTMLAttr

Alias

safeHTMLAttr

Given a site configuration that contains this menu entry:

hugo.

menus:
  main:
  - name: IRC
    url: irc://irc.freenode.net/#golang

[menus]
[[menus.main]]
    name = 'IRC'
    url = 'irc://irc.freenode.net/#golang'

{
   "menus": {
      "main": [
         {
            "name": "IRC",
            "url": "irc://irc.freenode.net/#golang"
         }
      ]
   }
}

Attempting to use the url value directly in an attribute:

{{ range site.Menus.main }}
  <a href="{{ .URL }}">{{ .Name }}</a>
{{ end }}

Will produce:

<a href="#ZgotmplZ">IRC</a>

ZgotmplZ is a special value, inserted by Go’s template/html package, that indicates that unsafe content reached a CSS or URL context.

To indicate that the HTML attribute is safe:

{{ range site.Menus.main }}
  <a {{ printf "href=%q" .URL | safeHTMLAttr }}>{{ .Name }}</a>
{{ end }}
