$('a').one('click', callback) is executed at most once *per element*. $('a').one_for_all('click', callback) is executed at most once… *for all elements*.

1 - one_for_all.js

// Works with Zepto/jQuery
$.fn.one_for_all = function(type, callback) {
  var $all = $(this)

  $all.on(type, function(e) {
    $all.off(type)
    callback(e)
  })
}

2 - example.js

$links = $('a')

// .one()
$links.one('click', function(e) { console.log('clicky') })

$links.eq(0).trigger('click') // => clicky
$links.eq(0).trigger('click')
$links.eq(1).trigger('click') // => clicky
$links.eq(1).trigger('click')
$links.eq(2).trigger('click') // => clicky
$links.eq(2).trigger('click')

// .one_for_all()
$links.one_for_all('click', function(e) { console.log('clicky') })

$links.eq(0).trigger('click') // => clicky
$links.eq(0).trigger('click')
$links.eq(1).trigger('click')
$links.eq(1).trigger('click')
$links.eq(2).trigger('click')
$links.eq(2).trigger('click')
