If you're using angularJS or some variant of the Q promise library, then you have a .all() method that solves this exact problem.

var savePromises = [];
angular.forEach(models, function(model){
  savePromises.push(
    model.saveToServer()
  )
});

$q.all(savePromises).then(
  function success(results){...},
  function failed(results){...}
);
