• 弹窗封装文件 : ImportModal.tsx

import React, { useState, useImperativeHandle, forwardRef } from 'react'
import { Form, Modal, Select } from 'antd'
type TParams = { ttl: any[] }
// forwardRef : 传递ref
export const ImportTTLModal = forwardRef<any>(
  (props, ref) => {
    const [params, setParams] = useState<any>()
    const [isModalVisible, setIsModalVisible] = useState(false);
    // 确定事件
    const handleOk = () => {
      setIsModalVisible(false);
    };
  	// 取消事件
    const handleCancel = () => {
      setIsModalVisible(false);
    };
    // useImperativeHandle：自定义 ref.current
    useImperativeHandle(
      ref,
      () => ({
        show:(params: TParams) => {
            // 保存参数
            setParams(params)
            /** 改变状态 */
            setIsModalVisible(true)  
          },
      }),
      []
    )

    return (
      <Modal
        title='弹窗'
        visible={isModalVisible}
        onOk={handleOk} 
        onCancel={handleCancel}
      >
        <div>弹窗内容</div>
      </Modal>
    )
  }
)

• 使用自定义弹窗

import { Button, } from 'antd'
import React, { useRef, useState } from 'react'
import { ImportModal } from './components/ImportModal'

const Main: React.FC<any> = () => {
  const refImportModal = useRef<any>(null)
  const ttl = [7, 14, 30, 60, 90, 120, 150, 180, 270, 360, 720, -1]
  const showModal = () => {
  	// 显示弹窗并传参。
    refImportModal.current?.show({
      ttl: ttl,
    })
  }
  return (
    <div>
      <Button onClick= { showModal } >
        弹出弹窗
      < /Button>
      < ImportModal ref = { refImportModal } />
    </div>
    )
}
export default Main
