Given a site configuration that contains this menu entry:
|
||
|
|
|
||
|
|
{{< code-toggle file=hugo >}}
|
||
|
|
[[menus.main]]
|
||
|
|
name = "IRC"
|
||
|
|
url = "irc://irc.freenode.net/#golang"
|
||
|
|
{{< /code-toggle >}}
|
||
|
|
|
||
|
|
Attempting to use the `url` value directly in an attribute:
|
||
|
|
|
||
|
|
```go-html-template
|
||
|
|
{{ range site.Menus.main }}
|
||
|
|
<a href="{{ .URL }}">{{ .Name }}</a>
|
||
|
|
{{ end }}
|
||
|
|
```
|
||
|
|
|
||
|
|
Will produce:
|
||
|
|
|
||
|
|
```html
|
||
|
|
<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:
|
||
|
|
|
||
|
|
```go-html-template
|
||
|
|
{{ range site.Menus.main }}
|
||
|
|
<a {{ printf "href=%q" .URL | safeHTMLAttr }}>{{ .Name }}</a>
|
||
|
|
{{ end }}
|
||
|
|
```
|
||
|
|
|
||
|
|
{{% note %}}
|
||
|
|
As demonstrated above, you must pass the HTML attribute name _and_ value through the function. Applying `safeHTMLAttr` to the attribute value has no effect.
