The internal v-form component makes it easy to add validation to form inputs. All input components have a rules prop which takes an array of functions. These functions allow you to specify conditions in which the field is valid or invalid. Whenever the value of an input is changed, each function in the array will receive the new value. If a function returns false or a string, validation has failed.

Rules allow you to apply custom validation on all form components. These are validated sequentially and will display a maximum of 1 error at a time, so make sure you order your rules accordingly.

Vee-validate是另一个验证插件，允许您检查您的表单。一个警告是，当您使用value属性时必须添加type="checkbox"来正确验证一个v-checkbox。
