自定义标记图标与反应传单

标签: icons maps leaflet marker react-leaflet

我尝试了在网络上找到的所有东西,Stackoverflow和Github,我仍然无法做到。

我想用自定义图标制作自定义标记,但是我的代码总是出现错误:'TypeError:options.icon.createIcon不是函数'

这是我的代码(文件夹路径没有错误,一切都在src / js或src / img中)

Icon.js

import L from 'leaflet';

const iconPerson = L.Icon.extend({
  options: {
    iconUrl: require('../img/marker-pin-person.svg'),
    iconRetinaUrl: require('../img/marker-pin-person.svg'),
    iconAnchor: null,
    popupAnchor: null,
    shadowUrl: null,
    shadowSize: null,
    shadowAnchor: null,
    iconSize: new L.Point(60, 75),
    className: 'leaflet-div-icon'
  }
});

export { iconPerson };

MarkerPinPerson

import React from 'react';
import { Marker } from 'react-leaflet';
import {  iconPerson  } from './Icons';


export default class MarkerPinPerson extends React.Component {

  render() {

    return (
      <Marker
        position={this.props.markerPosition}
        icon={ iconPerson }
        >
      </Marker>
      );
  }
}

真的在寻求你的帮助!

我终于找到了 Icon.js 文件的正确代码:

import L from 'leaflet';

const iconPerson = new L.Icon({
    iconUrl: require('../img/marker-pin-person.svg'),
    iconRetinaUrl: require('../img/marker-pin-person.svg'),
    iconAnchor: null,
    popupAnchor: null,
    shadowUrl: null,
    shadowSize: null,
    shadowAnchor: null,
    iconSize: new L.Point(60, 75),
    className: 'leaflet-div-icon'
});

export { iconPerson };

在试图弄清楚如何渲染自定义图标服务器端(使用react-leaflet-universal)时,我被带到这里。我以为我会发布此邮件,以防将来有人出于同样的原因而在这里找到自己。就像在react-leaflet-markercluster的情况下一样,我能够通过在return函数中要求传单来使此工作正常进行,例如:

<Map center={this.props.center}
             zoom={zoom}
             className={leafletMapContainerClassName}
             scrollWheelZoom={false}
             maxZoom={18}
             preferCanvas={false}
        >
            {() => {
                const MarkerClusterGroup = require('react-leaflet-markercluster').default;
                const L = require('leaflet');

                const myIcon = L.icon({
                    iconUrl: require('../assets/marker.svg'),
                    iconSize: [64,64],
                    iconAnchor: [32, 64],
                    popupAnchor: null,
                    shadowUrl: null,
                    shadowSize: null,
                    shadowAnchor: null
                });

                return (
                    <React.Fragment>
                        <TileLayer
                            url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
                            attribution=''
                            setParams={true}
                        />
                        <MarkerClusterGroup>
                            {coordArray.map(item => {
                                return (
                                    <Marker icon={myIcon} key={item.toString()} position={[item.lat, item.lng]}>
                                        {item.title && <Popup>
                                            <span>{item.title}</span>
                                        </Popup>}
                                    </Marker>
                                )
                            })}
                        </MarkerClusterGroup>
                    </React.Fragment>
                );
            }}
        </Map>

您不需要使用require。无需提供iconUrl =“ ../assets/name”,只需导入png或svg,然后将源提供给iconUrl即可。看下面的例子:

//首先导入图片或svg

import heart from "../../images/other/love.svg";

//将来源提供给您的图标

let loveIcon = L.icon({
  iconUrl: heart,
  iconRetinaUrl: heart,
  iconAnchor: [5, 55],
  popupAnchor: [10, -44],
  iconSize: [25, 55],
});

//只需将其添加到您的地图

L.marker([28, 50], {
       icon: loveIcon,
     }).addTo(map);

我也遇到了同样的问题。 这是我的工作解决方案:

`import L from 'leaflet';
import marker from '../assets/placer.svg';
const myIcon = new L.Icon({
    iconUrl: marker,
    iconRetinaUrl: marker,
    popupAnchor:  [-0, -0],
    iconSize: [32,45],     
});`
