these are js autocleaners for attributes we'll be validating with a regexp server side

autoclean.js

  /* autocleaning attributes */
  var cleaner = {};
  cleaner.phone = function(){
    var regex   = /[^0-9x]/g;
    var value   = $(this).val();
    if (regex.test(value)) {
      $(this).val(value.replace(regex, ''));
    }
  };
  cleaner.date = function(){
    var regex  = /[^0-9\-]/g;
    var value  = $(this).val();
    value = value.replace(/\/|\s/g, '-');
    value = value.replace(/^(\d{2})$|^(\d{2}-\d{2})$/, "$1$2-");
    value = value.replace(/^(\d{1})-/, "0$1-");
    value = value.replace(/^(\d{2})-(\d{1})-/, "$1-0$2-");
    value = value.replace(regex, '');
    $(this).val(value.replace(/(\-\-)+/g, '-'));
  };
  
  $('.autoclean.phone').live('blur', cleaner.phone).live('keyup', cleaner.phone);
  $('.autoclean.date').live('blur',  cleaner.date).live('keyup',  cleaner.date);
