Call a function in template while iterating using Range

[DEXTER]

Hi
How do I call a function in template while iterating

If I call the function outside the
{{range $index,$val := .Options.Attrs}}
{{$index}}
{{end}}
{{.GetOptionKey 1}} //GetOptionKey is my function

the function executes

But when I try this

{{range $index,$val := .Options.Attrs}}
{{.GetOptionKey $index}} //i want to pass the variable index to
the function
{{end}}

It does parse the template file and does not return any error. The
template block above the range condition is parsed & returned

Maybe you can pass the function using http://golang.org/pkg/html/template/#Template.Funcs.
See "Defining Functions" section at http://jan.newmarch.name/golang/template/chapter.html for example.

ranging changes what the dot points at. Try this:

{{if $self := .}}

{{range $index,$val  := .Options.Attrs}}
                     {{$self.GetOptionKey $index}} //i want to pass the variable index to
the function
{{end}}{{end}}

Hi,
Thanks this worked.

{if $self := .}}
{{range $index,$val := .Options.Attrs}}

{{$k := $self.Options.GetOptionKey $index}}
<div id="{{$k}}">{{$k}}</div>
{{end}}
{{end}}

Now I have another problem
Can I call function that returns multiple values from a template

{if $self := .}}
{{range $index,$val := .Options.Attrs}}

{{$k,$v := $self.Options.GetOptionKey $index}}
<div id="{{$k}}">{{$v}}</div>
{{end}}
{{end}}

It only works when the function returns 1 value
