antd modal拖拽，自定义modal拖拽react-draggable

"antd": "^4.9.4"时，可以直接使用如下代码：

import React, { Component } from "react";
import { Modal, Button } from 'antd';
import Draggable from 'react-draggable';
class Drag extends Component {constructor(props) {super(props);this.state = {visible: false,disabled: true,bounds: { left: 0, top: 0, bottom: 0, right: 0 },};}draggleRef = React.createRef();showModal = () => {this.setState({visible: true,});};handleOk = e => {console.log(e);this.setState({visible: false,});};handleCancel = e => {console.log(e);this.setState({visible: false,});};onStart = (event, uiData) => {const { clientWidth, clientHeight } = window?.document?.documentElement;const targetRect = this.draggleRef?.current?.getBoundingClientRect();this.setState({bounds: {left: -targetRect?.left + uiData?.x,right: clientWidth - (targetRect?.right - uiData?.x),top: -targetRect?.top + uiData?.y,bottom: clientHeight - (targetRect?.bottom - uiData?.y),},});};render() {const { bounds, disabled, visible } = this.state;return (<><Button onClick={this.showModal}>Open Draggable Modal</Button><Modaltitle={<divstyle={
   {width: '100%',cursor: 'move',}}onMouseOver={() => {if (disabled) {this.setState({disabled: false,});}}}onMouseOut={() => {this.setState({disabled: true,});}}// fix eslintjsx-a11y/mouse-events-have-key-events// https://github.com/jsx-eslint/eslint-plugin-jsx-a11y/blob/master/docs/rules/mouse-events-have-key-events.mdonFocus={() => {}}onBlur={() => {}}// end>Draggable Modal</div>}visible={visible}onOk={this.handleOk}onCancel={this.handleCancel}modalRender={modal => (<Draggabledisabled={disabled}bounds={bounds}onStart={(event, uiData) => this.onStart(event, uiData)}><div ref={this.draggleRef}>{modal}</div></Draggable>)}><p>Just don&apos;t learn physics at school and your life will be full of magic andmiracles.</p><br /><p>Day before yesterday I saw a rabbit, and yesterday a deer, and today, you.</p></Modal></>);}
}
export default Drag;

"antd": "^3.26.16"，低版本antd无法实现拖拽，所以我自己写了一个modal，下面为完整代码

import React, { Component } from "react";
import { Button, Icon } from 'antd';
import Draggable from 'react-draggable';
import "./Draggable.css";
class Drag extends Component {constructor(props) {super(props);this.state = {visible: false,};}showModal = () => {this.setState({visible: true,});};handleOk = e => {this.setState({visible: false,});};handleCancel = e => {this.setState({visible: false,});};render() {const { visible } = this.state;return (<><Button onClick={this.showModal}>Open Draggable Modal</Button>{visible&&<div className="drag_modal_container"><div className="drag_modal_mask"></div><div className="drag_modal_wrap"><Draggable><div className="drag_modal"><div className="drag_modal_content"><button className="drag_modal_close"><span className="drag_modal_close_icon"><Icon type="close" onClick={this.handleCancel}/></span></button><div className="drag_modal_header"><div className="drag_modal_title">Draggable Modal</div></div><div className="drag_modal_body"><p>Just don&apos;t learn physics at school and your life will be full of magic andmiracles.</p><br /><p>Day before yesterday I saw a rabbit, and yesterday a deer, and today, you.</p></div><div className="drag_modal_footer"><Button onClick={this.handleCancel}>Cancel</Button><Button type="primary" className="drag_right_button" onClick={this.handleOk}>OK</Button></div></div></div></Draggable></div></div>}</>);}
}
export default Drag;
