antd Model.confirm 添加自定义按钮

有时候需求就是这样，不做也得做 

import React, { Component } from 'react';
import { Link, Prompt } from 'react-router-dom';
import {Row,Col,message, Modal,Input,Button,Select,Icon } from 'antd';
import 'antd/dist/antd.css';

const modal = Modal.confirm;

export default class Page3 extends Component {

    state={

    }

  // 销毁所有弹框
    closeConfirm(){
        Modal.destroyAll();
    }

  //向用户确认,返回true就直接跳转，返回字符串有提示框出来，返回false不跳转
    confirmToSave(location){
        modal({
            title: '',
            content: 

                内容已修改，离开时是否需要保存
                取消
            
,
            okText: '是',
            cancelText:'否',
            mask:false,
            icon: ,
            onOk:()=>{    // 点击'是',处理一些业务在跳转
                setTimeout(()=>{ // 两秒后跳转页面
                    window.location.href = location.pathname;
                },2000);
                return new Promise((resolve, reject) => {
                    setTimeout(Math.random() > 0.5 ? resolve : reject, 1000);
                }).catch(() => console.log('Oops errors!'));
            },
            onCancel:() => {    // 点击 ‘否’，说明用户不想做任何事情，直接跳转
                window.location.href = location.pathname;
            },
        });
        return false;
    }

  render() {
    return (
