访问golang模板循环内的循环外值

Question

I have this struct :

type Site struct {
    Name string
    Pages []int
}

I pass an instance of Site to a template.

If I want to write a list of all pages, I do

{{range .Pages}}
    <li><a href="{{.}}">{{.}}</a></li>
{{end}}

Now, what's the simplest way to use the Name field inside the loop (for example to change the href to Name/page) ?

Note that a solution based on the fact that the external object is the global one that was passed to the template would be OK.

Answer 1

You should know that the variable passed in to the template is available as $.

{{range .Pages}}
    <li><a href="{{$.Name}}/{{.}}">{{.}}</a></li>
{{end}}

(See the text/template documentation under "Variables".)
