我在 google maps 文档中找到了很多有用的信息，但是在 html 中简单地使用了 js，react老实说我不明白。

源代码：

import React, { Component } from 'react';
import {Map, InfoWindow, Marker, GoogleApiWrapper} from 'google-maps-react';

export class MainMap extends Component {
    render() {
        return (
            <div>
                <h1 className="text-center">My Maps</h1>
            <Map google={this.props.google}
                 style={{width: '80%', margin: 'auto'}}
                 className={'map'}
                 zoom={14}>
                <Marker
                    title={'The marker`s title will appear as a tooltip.'}
                    name={'SOMA'}
                    position={{lat: 37.778519, lng: -122.405640}} />
                <Marker
                    name={'Dolores park'}
                    position={{lat: 37.759703, lng: -122.428093}} />
                <Marker />
                <Marker
                    name={'Your position'}
                    position={{lat: 46.475640, lng: 30.759497}}/>
            </Map>
            </div> …

我正在使用反应,我试图简单地显示我的弹出窗口,但我有这个错误

Uncaught TypeError: Cannot set property 'onclick' of null
    at eval (index.js:33)
    at Object../src/index.js (main.js:680)
    at __webpack_require__ (main.js:20)
    at eval (index.js:9)
    at Object../examples/src/index.js (main.js:97)

    at Object.0 (main.js:702)
    at __webpack_require__ (main.js:20)
    at main.js:84

这是我的完整index.js

import React from 'react';
import './style.scss';
import ReactDOM from "react-dom";

const modal = document.getElementById('myModal');

const btn = document.getElementById("myBtn");

const span = document.getElementsByClassName("close")[0];

btn.onclick = function() {
    modal.style.display = "block";
};

span.onclick = function() {
    modal.style.display = "none";
};

window.onclick = function(event) …

这是我的代码

select top 100
       ih.streetname,
       ih.district,
       ih.intervalhouse
from vw_pn_intervalshouse ih
inner join vw_pn_street s on s.id = ih.streetname
CROSS APPLY STRING_SPLIT(ih.intervalhouse, ',');

我正在尝试使用string_split，但结果不正确

我会告诉你一些输出

district        streetname      intervalhouse
32000100001832  1008302496093   1,17
32000100001832  1008302496093   1,17
32000100001832  1008302496095   8,10,12
32000100001832  1008302496095   8,10,12
32000100001832  1008302496095   8,10,12

结果一定像

district        streetname      intervalhouse
32000100001832  1008302496093   1
32000100001832  1008302496093   17
32000100001832  1008302496095   8
32000100001832  1008302496095   10
32000100001832  1008302496095   12

可能是什么问题呢？有什么解决办法吗？
