Weight
文法
MENUENTRY.Weight
戻り値
int
If you define the menu entry automatically, the Weight method returns the page’s Weight.
If you define the menu entry in front matter or in site configuration, the Weight method returns the weight property, falling back to the page’s Weight.
In this contrived example, we limit the number of menu entries based on weight:
<ul>
{{ range .Site.Menus.main }}
{{ if le .Weight 42 }}
<li><a href="{{ .URL }}">{{ .Name }}</a></li>
{{ end }}
{{ end }}
</ul>
