Iterating over jQuery DOM elements in coffeescript: $(@). shortcut

Question

I have a great many loops in my coffeescript that iterate over a collection of DOM elements, and execute more jQuery. These functions tend to look like this:

$('.iterable.object').each ->
    $(@).doThis
    $(@).doThat

    ## More complicated usage
    $(@).jqueryPluginCall
        x: $(@).data('attr1')
        x: $(@).data('attr2')

    ## More complicated usage
    $(@).children('ul.animateable').each ->
        if $(@).data('animation') is "fancy"
            $(@).animate fancy: animation
        else
            $(@).animate simple: animation
        $(@).focus(
            ->
                $(@).animate some: more
            , ->
                $(@).animate even: more
        ) ## Or however you do double callbacks

I made about 3 typos entering the $(@). 's again and again, and it's becoming a pain.

There isn't a shortcut syntax for $(@) ? It's kind of a pain to type and seems like a pretty common syntax. It'd be cool if it operated similarly to @ as an automated function caller, like &doThis instead of &.doThis .

EDIT: I'd like to be able to define an alias right in javascript after jQuery loads that responds with the DOM element when called & and chains to methods &doThis , rather than at the top of each loop the way @bennedich suggests below.

Answer 1

How about function chaining:

$('.iterable.object').each ->
  $(@)
    .doThis()
    .doThat()

Or storing $(@) to a variable:

$('.iterable.object').each ->
  t = $(@)
  t.doThis()
  t.doThat()

Or a combination of the two. Last thing I can think of is IDE snippets, eg textmate will let you configure letter+TAB be replaced by $(@) .
