Question

目前，我已使用InfoModal成功地将地图组件渲染为可重用组件，以显示图标，但是，我没有修改标准的红色Google Map图标，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，如何做到这一点（这可能很简单），但我不确定react-google-maps是否有东西用于以插件或正确格式创建自定义标记。

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: (
          <svg
            id="Layer_1"
            xmlns="http://www.w3.org/2000/svg"
            width="16"
            height="16"
            viewBox="0 0 16 16"

            />
          </svg>
        )
      }, 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,
            showInfo: true
          }
        }
        return marker
      })
    })
  }

  handleMarkerClose (targetMarker) {
    this.setState({
      markers: this.state.markers.map(marker => {
        if (marker === targetMarker) {
          return {
            ...marker,
            showInfo: false
          }
        }
        return marker
      })
    })
  }

  render () {
    return (
      <MapGoogleMap
        containerElement={
          <div style={{ height: `500px` }} />
        }
        mapElement={
          <div style={{ height: `500px` }} />
        }
        center={this.state.center}
        markers={this.state.markers}
        onMarkerClick={this.handleMarkerClick}
        onMarkerClose={this.handleMarkerClose}
      />
    )
  }
}

Answer 1

标记扩展运算符在key = {index}之上缺失。这是正确的代码。图标本身在另一个名为mapDefaults.js的文件中定义，如果有人遇到这个问题，请不要犹豫与我联系。

<Marker
        {...marker}
        key={index}
        position={marker.position}
        onClick={() => props.onMarkerClick(marker)}
>

这就是我固定的方式

let iconMarker = new window.google.maps.MarkerImage(
                "https://lh3.googleusercontent.com/bECXZ2YW3j0yIEBVo92ECVqlnlbX9ldYNGrCe0Kr4VGPq-vJ9Xncwvl16uvosukVXPfV=w300",
                null, /* size is determined at runtime */
                null, /* origin is 0,0 */
                null, /* anchor is bottom center of the scaled image */
                new window.google.maps.Size(32, 32)
            );
            return(
                <Marker
                    icon={iconMarker}
                    key={marker.id}
                    onClick={onClick}
                    position={{ lat: parseInt(marker.latitude), lng: parseInt(marker.longitude)}}>
                    {props.selectedMarker === marker &&
                    <InfoWindow>
                        <div style={{'color':'black'}}>
                           Shop {marker.name} {stretTexte}
                        </div>
                    </InfoWindow>}
                </Marker>
            )

富兰克林，您可以在React Google地图中使用。它具有两个优点，使其可以在信息窗口或简单的Marker组件上使用。我们有图标选项可自定义标记。我们有完全可定制的div元素。您只需传递图标网址即可。 LabelStyling是可选的。随时问任何问题。

import { MarkerWithLabel } from 'react-google-maps/lib/components/addons/MarkerWithLabel';

var markerStyling= {
  clear: "both", display: "inline-block", backgroundColor: "#00921A", fontWeight: '500',
  color: "#FFFFFF", boxShadow: "0 6px 8px 0 rgba(63,63,63,0.11)", borderRadius: "23px",
  padding: "8px 16px", whiteSpace: "nowrap", width: "160px", textAlign: "center"
};

 <MarkerWithLabel
  key={i}
  position={marker.position}
  labelAnchor={new google.maps.Point(75, 90)}
  labelStyle={markerStyling}
  icon={{
    url: '/build/icon/markPin.svg',
    anchor: new google.maps.Point(5, 58),
  }}
>
  <div>
    <p> My Marker </p>
  </div>
</MarkerWithLabel>
