antdv3 resetFields

The `resetFields` method of Ant Design v3 is used to reset the values of one or more form fields to their initial state. This method can be called on the `Form` instance or on a `Form.Item` instance.

Here's an example of calling `resetFields` on a `Form` instance:

import { Form, Input, Button } from 'antd';

const MyForm = () => {
  const [form] = Form.useForm();

  const handleReset = () => {
    form.resetFields();
  };

  return (
    <Form form={form}>
      <Form.Item name="username" label="Username">
        <Input />
      </Form.Item>
      <Form.Item name="password" label="Password">
        <Input.Password />
      </Form.Item>
      <Button onClick={handleReset}>Reset</Button>
    </Form>
  );
};

In the above example, the `handleReset` function is called when the "Reset" button is clicked. This function calls `resetFields` on the `form` object, which resets the values of both the "username" and "password" fields to their initial state.

You can also pass an array of field names to `resetFields` to only reset specific fields:

const handleReset = () => {
  form.resetFields(['username']);
};

In this example, only the "username" field will be reset when the "Reset" button is clicked.
