【问题描述】:
目前,我已经成功地将地图组件渲染成一个可重用的组件,使用 InfoModal 显示一个图标,但是,标准的红色谷歌地图图标我没有修改,我想自己创建一个自定义图标。我不确定 ES6 和 JSX 语法我需要做什么。我查看了 react-google-maps 问题并试图查看是否有任何当前或更新的材料可以做到这一点(这可能很简单),但我不确定 react-google-maps 是否有自定义的东西以插件或正确格式创建标记。
import React, { Component } from 'react'
import { withGoogleMap, GoogleMap, Marker, InfoWindow } from 'react-google-maps'
import { DEFAULT_MARKER } from '../../constants/mapDefaults'
const MapGoogleMap = withGoogleMap(props => (
<GoogleMap
defaultZoom={16}
center={props.center}
>
{props.markers.map((marker, index) => (
<Marker
key={index}
position={marker.position}
onClick={() => props.onMarkerClick(marker)}
>
{marker.showInfo && (
<InfoWindow onCloseClick={() => props.onMarkerClose(marker)}>
<div>{marker.infoContent}</div>
</InfoWindow>
)}
</Marker>
))}
</GoogleMap>
))
export default class Map extends Component {
state = {
center: {
lat: 28.3421135,
lng: -80.6149092
},
markers: [
{
position: new google.maps.LatLng(28.3431165, -80.6135908),
showInfo: false,
infoContent: (

}, DEFAULT_MARKER
]
}
handleMarkerClick = this.handleMarkerClick.bind(this);
handleMarkerClose = this.handleMarkerClose.bind(this);
handleMarkerClick (targetMarker) {
this.setState({
markers: this.state.markers.map(marker => {
if (marker === targetMarker) {
return {
...marker,

return marker

handleMarkerClose (targetMarker) {
this.setState({

return {
...marker,

}
}
return marker
})
})
}
render () {
return (
<MapGoogleMap

<div style={{ height: `500px` }} />
}
mapElement={

}
center={this.state.center}
