antd安装启动后报错Variable @primary-color-hover is undefined

报错前package.json中依赖版本信息:

"dependencies": {
    ...
    "@ant-design/pro-form": "^1.15.1",
    "@ant-design/pro-layout": "^6.15.0",
    "@ant-design/pro-table": "^2.27.1",
    "antd": "4.9.4",
  },

错误原因:@ant-design/pro-layout@ant-design/pro-table包版本导致的,锁定为固定版本就可以了

"dependencies": { ... "@ant-design/pro-form": "^1.15.1", "@ant-design/pro-layout": "6.15.0", "@ant-design/pro-table": "2.27.1", "antd": "4.9.4", },

antd switch 赋值不成功

最近在使用antd switch时,遇到一个意外的问题,switch组件初始化赋值没成功

import React, { useEffect } from 'react';
import { Form, Switch } from 'antd';

const ModalCreater = ({ data, close, callback }) => {
  const [form] = Form.useForm();

  const onFinish = async (values) => {};

  useEffect(() => {
    if (data) {
      form.setFieldsValue({
        status: !!data.status,
      });
    } else {
      form.setFieldsValue({
        status: true,
      });
    }
  }, [data]);

  return (
    <Form
      form={form}
      onFinish={onFinish}
    >
      <Form.Item
        label="状态"
        name="status"
       >
        <Switch />
      </Form.Item>
            ...
    </Form>
  );
};

export default ModalCreater;

发现在赋值是,switch并没有按照指定状态选中

查看form文档得知,form在初始化值是,Form.Item默认初始化的属性值是value,这也就是组件值通过value填充的组件都没什么问题,比如Input、Select等,而Switch组件填充值为checked

知道问题原因后就好修改了:设置Form.Item渲染属性值checked,通过valuePropNameapi来实现

使用方式如下:

<Form.Item
  label="状态"
  name="status"
  valuePropName="checked"
>
  <Switch />
</Form.Item>

大功告成!!!

antd Modal中使用Form组件, Modal确认按钮提交表单

方法一:使用okButtonProps属性来提交表单

设置htmlTypeformform为表单的name属性

import React from 'react';
import { Form, Modal } from 'antd';

const App = (props) => {
  const onFinish = (values) => {
    console.log('values', values);
  };

  return (
    <Modal
      title='标题'
      open={props.visible}
      onCancel={() => {}}
      destroyOnClose
      okButtonProps={{
        htmlType: 'submit',
        form: 'form',
      }}
    >
     <Form
        name='form'
        preserve={false}
        onFinish={onFinish}
      >
        ...
      </Form>
    </Modal>
  );
};

export default App;

方法二:使用ref来提交表单

import React, { useRef } from 'react';
import { Form, Modal } from 'antd';

const App = (props) => {
  const formRef = useRef();

  const onFinish = () => {
    const values = formRef.current?.getFieldsValue();
    console.log('values', values);
  };

  return (
    <Modal
      title='安全验证'
      open={props.visible}
      onCancel={() => { }}
      onOk={onFinish}
      destroyOnClose
      width={400}
    >
      <Form
        name='form'
        preserve={false}
        ref={formRef}
      >
        ...
      </Form>
    </Modal>
  );
};

export default App;

在使用过程中,优先使用第一种方式,因为这样可以效验form的rules,通过ref方法只能获取到表单提交的数据,做不到数据的效验

antd form validateTrigger效验时机

设置失去焦点效验

<Form.Item
  name='code'
  rules={[
    {
      required: true,
      message: '请输入验证码!',
    },
    {
      pattern: /^\d{4}$/,
      message: '请输入4位数字验证码',
    },
  ]}
  validateTrigger={['onBlur']}
>
  ...
</Form.Item>
