Question

以下是我的代码。在那，firstname，lastname，middlename输入田野在那里。我想使用单一方法来抛出错误那些领域。我只能通过里面的一个字段 validator.extend函数。例如：Validator.extend（'firstName'，{}）;. 但我想传递Validator.extend（'firstName'，'lastName'， 'middleName'，{}）;（或）Validator.extend（'fieldNames'，{}）;像这样。请帮忙。

您可以将对象传递给自定义验证（甚至可以在方法中返回）：

/Library/Python/2.7/site-packages/django/bin/django-admin.py startproject myproject

cd myproject
python manage.py runserver

如何使用vuejs2中的vee-validation为输入字段编写自定义/通用验证
