Concis组件库封装——Popover气泡卡片

您好，如果喜欢我的文章，可以关注我的公众号「量子前端」，将不定期关注推送前端好文~

气泡卡片...顾名思义，移动到或点击某块区域，出现一个气泡卡片dialog，组件库文档如下：

主要支持的有移动或点击触发，以及不同方向的气泡卡片，并提供了气泡卡片宽度，内容为调用端的DOM，样式也在调用端所控制。 API能力如下： 源码如下：

import React, {
  FC,
  memo,
  ReactNode,
  useState,
  useEffect,
  useMemo,
  useRef,
} from 'react';
import lodash from 'loadsh';
import './index.module.less';

interface popoverProps {
  children?: ReactNode;
  /**
   * @description 触发形式 hover/click
   * @default hover
   */
  type?: string;
  /**
   * @description 对齐方式 left/right/top/bottom
   * @default bottom
   */
  align?: string;
  /**
   * @description 卡片内容
   * @default <></>
   */
  content: ReactNode;
  /**
   * @description 卡片宽度
   * @default 200px
   */
  dialogWidth?: number;
  /**
   * @description 提供给调用层的卡片显示隐藏状态
   * @default false
   */
  propsVisiable?: boolean;
  /**
   * @description 卡片显示隐藏回调
   */
  onVisableChange?: Function;
}
type alignStyle = {
  left?: string;

  top?: string;
  bottom?: string;
};
const Popover: FC<popoverProps> = (props) => {
  const {
    children,
    type = 'hover',
    align = 'bottom',
    content,

  const showBtnRef = useRef();

    }
    return {
      width: showDialog ? `${dialogWidth}px` : '0px',
      height: showDialog ? '' : '0px',
      opacity: showDialog ? 1 : 0,

  return (

export default memo(Popover);
