Map 组件是其他组件的基础,Map 组件会给所有的子组件注入三个属性 map
,container
和 AMap
,
⚠️ 注意
- 组件
<Map>
必须包裹在<APILoader>
组件内,该组件作用是加载高德地图 SDK。- 其他地图组件必须作为
<Map>
的子组件使用;
import { Map, APILoader } from '@uiw/react-amap';
// 或者单独安装使用
import { Map } from '@uiw/react-amap-map';
Map 的父组件必须具有宽度和高度;
import React from 'react';
import ReactDOM from 'react-dom';
import { Map, APILoader } from '@uiw/react-amap';
const Demo = () => (
<div style={{ width: '100%', height: '300px' }}>
<APILoader akay="a7a90e05a37d3f6bf76d4a9032fc9129">
<Map />
</APILoader>
</div>
);
export default Demo
通过 React 的 Context 提供了一个无需
为每层组件手动注入 ,map
和 container
三个属性 AMap
props
,就能在组件树间进行传递。
import React, { useRef, useEffect } from 'react';
import ReactDOM from 'react-dom';
import { useMap, useMapContext, APILoader, Provider } from '@uiw/react-amap';
const Marker = () => {

const { setContainer } = useMap({
container: warpper.current,
center: [116.397428, 39.90923],
zoom: 10
});
useEffect(() => {
if (map) {
const marker = new AMap.Marker({
icon: new AMap.Icon({
imageSize: new AMap.Size(25, 34),
image: '//a.amap.com/jsapi_demos/static/demo-center/icons/poi-marker-default.png'
}),
position: [116.405285,39.904989],
offset: new AMap.Pixel(-13, -30)
});
// 创建点标记
const marker1 = new AMap.Marker({
position: new AMap.LngLat(116.32945,39.939772)
});
map.add(marker1);
marker.setMap(state.map);
}
}, [map]);

获取地图实例对象。
import ReactDOM from 'react-dom';
