`safeHTMLAttr` declares the provided string as a "safe" HTML attribute
|
|
from a trusted source (e.g., ` dir="ltr"`) to prevent Go html/template from filtering it as unsafe.
|
|
|
|
Example: Given a site-wide `config.toml` that contains this menu entry:
|
|
|
|
```toml
|
|
[[menu.main]]
|
|
name = "IRC: #golang at freenode"
|
|
url = "irc://irc.freenode.net/#golang"
|
|
```
|
|
|
|
* <span class="bad">`<a href="{{ .URL }}">` → `<a href="#ZgotmplZ">`</span>
|
|
* <span class="good">`<a {{ printf "href=%q" .URL | safeHTMLAttr }}>` → `<a href="irc://irc.freenode.net/#golang">`</span>
