在警报框中显示所有验证错误

Question

Is it possible to list all validation errors in alertbox. Currently its showing only the first instance of the error.

function form_validation_alert(type, name, num){
  name = name.replace(/^\W*(\w*)\W*$/, "$1");
  msg = form_validation_alerts[type];
  msg = msg.replace('%%Name%%', name.substr(0, 1).toUpperCase()+name.substr(1, name.length-1).toLowerCase());
  msg = msg.replace('%%name%%', name.toLowerCase());
  msg = msg.replace('%%num%%', num);

  alert(msg);

  return false;
}

try to concatenate all messages.

function form_validation_alert(type, name, num){
  name = name.replace(/^\W*(\w*)\W*$/, "$1");
  msg = form_validation_alerts[type];
  msg = msg + msg.replace('%%Name%%', name.substr(0, 1).toUpperCase()+name.substr(1, name.length-1).toLowerCase());
  msg = msg + msg.replace('%%name%%', name.toLowerCase());
  msg = msg + msg.replace('%%num%%', num);

  alert(msg);

  return false;
}
