rescan()

[TimNZ]

rescan() needs work

• You are checking for attribute [ays-orig], which is never set anywhere. I guess you only want to pick up fields not existing before.
• Subsequently all matchings fields are rescaned (no problem with this as I want to refresh the values after I have saved the form via ajax), but bind handlers are rebound each time and duplicated.

For my purposes the rescan should be complete, or support a 'all' parameter. Perhaps use namespaces for the events as well. I'm no JS expert, so feel free to question or criticise anything I said :)

var rescan = function(all) {
  var $form = $(this);
  var fields = $form.find(settings.fieldSelector);
  if (!all) fields = fields.not("[ays-orig]");
  $(fields).each(storeOrigValue);
  $(fields).unbind('change.areYouSure keyup.areYouSure', checkForm).bind('change.areYouSure keyup.areYouSure', checkForm)
};
