Marker 点标注组件

表示地图上一个图像标注。

import { Marker, useMarker } from '@uiw/react-baidu-map';
// 或者单独安装使用
import Marker, { useMarker } from '@uiw/react-baidu-map-marker';

🚧 注意：需要使用到 <Provider>，新的封装 Marker 组建使用了 Context 来避免 map 对象传来传去。

基本用法

import React from 'react';
import { Map, Provider, Marker, APILoader } from '@uiw/react-baidu-map';

const Demo = () => {
  function markerRef(props) {
    if (props && props.marker) {
      console.log('marker::', props.marker, props.map, props.BMap);
    }
  }
  return (
    <div style={{ width: '100%' }}>
      <APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
        <Provider>
          <Map widget={['NavigationControl']} zoom={13} style={{ height: 350 }}>
            <Marker ref={markerRef} animation={2} position={{ lng: 121.411535, lat: 31.222965 }} />
            <Marker position={{ lng: 121.465145, lat: 31.241245 }} />
            <Marker position={{ lng: 121.466008, lat: 31.220001 }} type="loc_red" /> 
            <Marker position={{ lng: 121.501365, lat: 31.224942 }} type="simple_blue" />
            <Marker position={{ lng: 121.464858, lat: 31.202705 }} type="simple_red" />
            <Marker position={{ lng: 121.458534, lat: 31.224942}} type="start" />
            <Marker position={{ lng: 121.434962, lat: 31.200729 }} type="end" />
            <Marker position={{ lng: 121.478943, lat: 31.2531 }} type="location" />
            <Marker position={{ lng: 121.516888, lat: 31.249149 }} type="red1" />
            <Marker position={{ lng: 121.512576, lat: 31.240504 }} type="red2" />
            <Marker position={{ lng: 121.513726, lat: 31.233588}} type="blue3" />
            <Marker position={{ lng: 121.520912, lat: 31.234576}} type="blue4" />
            <Marker position={{ lng: 121.491879, lat: 31.195045}} type="dot_red" />
            <Marker position={{ lng: 121.485555, lat: 31.195045}} type="dot_blue" />
          </Map>
        </Provider>
      </APILoader>
    </div>
  );
};

export default Demo;

自定义标点

import React from 'react';
import { useState } from 'react';
import { Map, Provider, Marker, APILoader } from '@uiw/react-baidu-map';
const CustomIcon = () => {
  const [position, setPosition] = useState({ lng: 121.466008, lat: 31.220001 });
  const icon = new BMap.Icon('http://developer.baidu.com/map/jsdemo/img/fox.gif', new BMap.Size(300, 157));
  return (
    <>
      <button onClick={() => setPosition({lng: 121.545202, lat: 31.246679})}>设置 position</button>
      <Map zoom={13} center={{ lng: 121.460977, lat: 31.227906 }} style={{ height: 350 }}>
        <Marker position={position} icon={icon} animation={2} />
      </Map>
    </>
  );
}

const Demo = () => (
  <div style={{ width: '100%' }}>
    <APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
      <Provider>
        <CustomIcon />
      </Provider>
    </APILoader>
  </div>
);

export default Demo;

添加事件

import React from 'react';
import { useState } from 'react';
import { Map, Provider, Marker, APILoader } from '@uiw/react-baidu-map';

const CustomIcon = () => {
  const [count, setCount] = useState(0)
  const [message, setMessage] = useState('请点击标注点，小箭头!')
  const [addEvent, setAddEvent] = useState(false);
  const icon = new BMap.Icon('http://developer.baidu.com/map/jsdemo/img/fox.gif', new BMap.Size(300, 157));
  function clickHandle({ type, target}) {
    console.log('~~~~~clickHandle~~~~~', type, target);
    setMessage('啊哈哈！你真的点击了！');
    setCount(count + 1);
  }
  return (
    <>
      <div>{message} {count}</div>
      <Map zoom={13} center={{ lng: 121.460977, lat: 31.227906 }}>
        <Marker onClick={clickHandle} position={{ lng: 121.466008, lat: 31.220001 }}  />
      </Map>
    </>
  );
}

const Demo = () => (
  <div style={{ width: '100%', height: '350px' }}>
    <APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
      <Provider>
        <CustomIcon />
      </Provider>
    </APILoader>
  </div>
);

  const [isAddEvent, setIsAddEvent] = useState(false);
  const iconfox = new BMap.Icon('http://developer.baidu.com/map/jsdemo/img/fox.gif', new BMap.Size(300, 157));
  const iconfox1 = new BMap.Icon('http://api0.map.bdimg.com/images/copyright_logo.png', new BMap.Size(300, 157));
  const [icon, setIcon] = useState(iconfox);

使用 hooks

marker, setMarker, type, setType

import React from 'react';
import { useRef, useEffect, useState } from 'react';
import { Provider, APILoader, useMap, useMarker } from '@uiw/react-baidu-map';

const Example = () => {
  const divElm = useRef(null);
  const { setContainer, map } = useMap({ widget: ['GeolocationControl', 'NavigationControl'], zoom: 8 });
  const { setType, marker } = useMarker({ map, position: { lng: 121.444017, lat: 31.237787 } });
  useEffect(() => {
    if (divElm.current && !map) {
      setContainer(divElm.current);
    }
  });
  return (
    <>
      <button onClick={() => setType('red2')}>设置 red2</button>
      <button onClick={() => setType('loc_blue')}>设置 loc_blue</button>
      <button onClick={() => marker.setPosition(new BMap.Point(121.497197, 31.232847))}>设置坐标点</button>
      <button onClick={() => marker.setAnimation(2)}>设置动画</button>
      <button onClick={() => marker.setAnimation(null)}>取消动画</button>
      <div ref={divElm} style={{ height: 350 }} />
    </>
  )
}

const Demo = () => (
  <div style={{ width: '100%' }}>
    <APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
      <Provider>
        <Example />
      </Provider>
