vee-validate下meta的使用

const password = useField<string>("password");

const passwordHint = computed(() => {
  if (password.meta.dirty) {
    return "";
  }
  return "This should contain 8 to 128 characters with a mix of uppercase letters, lowercase letters and numbers.";
});

可以通过 password.meta.dirty 来判断 password输入是否发生改变,这两个属性是vee-validate提供的.
