parameters and helper functions about meteor-jade HOT 3 CLOSED

I am trying something similar:

UI.registerHelper 'e', (a) ->
  a

template(name='test')
  = e 'asd'
  // I also tried
  = e asd

Any advice on how to pass arguments to helpers?

from meteor-jade.

@juanpastas your method names aer a bit cryptic.

i think you can just use handlebars {{ }}

template(name='test')
  {{e "blah" }}

or pass an object too.
what you can't do, afaik is to pass array indexes eg.

UI.registerHelper 'arrayItem', (ary, idx) ->
  return ary[idx]

template(name='test')
  {{arrayItem stuff 3}}
  {{arrayItem stuff 4}}
  {{arrayItem stuff 5}}

# there is some weird syntax to get at array content inside a template, maybe:
 {{stuff.0}}

# but it doesnt work for parameter passing
 {{someFunc stuff.0 }}

overall meteor jade seems to have a lot of holes from the normal jade spec but there's usually one way of doing things that works. you just have to poke around to find it!

from meteor-jade.

Due to the lack of inline javascript expression, it's not (yet) possible to use something like:

a(title=trans(this.text))

Instead you should use the following workaround:

a(title="{{trans text}}")

I'm closing in favor of #1
