How to access out of loop value inside golang template's loop?

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}}

{{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.

Chris Gregori · Accepted Answer

You should know that the variable passed in to the template is available as $. {{range .Pages}}

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

What about: {{$name := .Name}} {{range $page := .Pages}}

{{end}} Or simply make Pages a map with Name as value? type Site struct { Pages map[string]string } {{range $page, $name := .Pages}}
