我的代码如下，我的react应用程序中没有使用任何外部库

import React, { Component } from "react";
import MarkerInfo from "./MarkerInfo";
import { render } from "react-dom";

class Map extends Component {
componentDidMount() {
    this.renderMap();
}

renderMarkerInfo = () => {
    return (
    <div id="markerinfo">
        <h1>THis is info marker</h1>
    </div>
    );
};

renderMap = () => {
    loadScript(
    "https://maps.googleapis.com/maps/api/js?key=KEY&callback=initMap"
    );
    window.initMap = this.initMap;
};

initMap = () => {
    var uluru = { lat: -25.363, lng: 131.044 };
    var map = new window.google.maps.Map(document.getElementById("map"), {
    zoom: 4,
    center: uluru
    });

    var contentString =
    '<div id="content">' +
    '<div id="siteNotice">' +
    "</div>" +
    '<h1 id="firstHeading" class="firstHeading">Uluru</h1>' +
    '<div id="bodyContent">' +
    "<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large " +
    "sandstone rock formation in the southern part of the " +
    "Northern Territory, central Australia. It lies 335&#160;km (208&#160;mi) " +
    "south west of the nearest large town, Alice Springs; 450&#160;km " +
    "(280&#160;mi) by road. Kata Tjuta and Uluru are the two major " +
    "features of the Uluru - Kata Tjuta National Park. Uluru is " +
    "sacred to the Pitjantjatjara and Yankunytjatjara, the " +
    "Aboriginal people of the area. It has many springs, waterholes, " +
    "rock caves and ancient paintings. Uluru is listed as a World " +
    "Heritage Site.</p>" +
    '<p>Attribution: Uluru, <a href="https://en.wikipedia.org/w/index.php?title=Uluru&oldid=297882194">' +
    "https://en.wikipedia.org/w/index.php?title=Uluru</a> " +
    "(last visited June 22, 2009).</p>" +
    "</div>" +
    "</div>";

    var infowindow = new window.google.maps.InfoWindow({
    content: contentString
    });

    var marker = new window.google.maps.Marker({
    position: uluru,
    map: map,
    title: "Uluru (Ayers Rock)"
    });
    marker.addListener("click", function() {
    infowindow.open(map, marker);
    });
};

render() {
    return (
    <div id="map">
        <MarkerInfo />
    </div>
    );
}
}

function loadScript(url) {
    var index = window.document.getElementsByTagName("script")[0];
    var script = window.document.createElement("script");
    script.src = url;
    script.async = true;
    script.defer = true;
    index.parentElement.insertBefore(script, index);
}

export default Map;

当前我正在显示info window硬编码文本，我想使用react组件显示它，我怎么能做到这一点？

我写了另一个组件，每当标记时我想动态显示react组件
