基本用法
官方原生 JS 实例:https://lbsyun.baidu.com/jsdemo.htm#c1_14
import React, { useState } from 'react';
import { Map, Label, APILoader } from '@uiw/react-baidu-map';
const Example = () => {
const [visiable, setVisiable] = useState(true);
const [content, setContent] = useState('上海市 <del>青浦区</del> 徐泾镇盈港东路');
function labelRef(props) {
if (props && props.label) {
console.log('label:', props.label, props.map, props.BMap);
}
}
return (
<>
<input value={content} onChange={(e) => setContent(e.target.value)} />
<button onClick={() => setVisiable(!visiable)}>{visiable ? '隐藏' : '显示'}</button>
<Map zoom={13} widget={['NavigationControl']} style={{ height: 350 }} >
<Label visiable={visiable} content={content} position={{ lng: 121.436256, lat: 31.246926 }} />
<Label
ref={labelRef}
title="wwww"
content={content}
position={{ lng: 121.501365, lat: 31.224942 }}
onClick={() => setContent('您!点击了文本标注!')}
/>
<div>
<Label content="test" visiable={visiable} title="wwww" position={{ lng: 121.501365, lat: 31.234942 }}>
children - 2<br /> 上海市 <del>青浦区</del> 徐泾镇盈港东路
</Label>
</div>
</Map>
</>
);
}
const Demo = () => (
<div style={{ width: '100%' }}>
<APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
<Example />
</APILoader>
</div>
);
export default Demo;
使用 hooks
label
, setLabel
import React from 'react';
import { useRef, useEffect, useState } from 'react';
import { Map, APILoader, Provider, useMap, useLabel, useMapContext } from '@uiw/react-baidu-map';
const Example = () => {
const [zoom, setZoom] = useState(15)
const divElm = useRef(null);
const { map } = useMapContext();
const { label, Portal } = useLabel({
content: '徐泾镇',
position: { lng: 121.501365, lat: 31.224942 },
onClick: () => {
console.log('点击事件!');
}
});
useEffect(() => {
if (map) {
// 启用滚轮放大缩小,默认禁用
map.setZoom(zoom);
}
}, [zoom, map]);
let counts = zoom || 15;
return (
<>
<button onClick={() => setZoom(counts-1)}>-</button>
<span>{zoom || 10}</span>
<button onClick={() => setZoom(counts+1)}>+</button>
<Portal><div>xxxxxx</div></Portal>
</>
)
}
const Demo = () => (
<div style={{ width: '100%' }}>
<APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
<Map zoom={9} widget={['NavigationControl']} style={{ height: 350 }} >
<Example />
</Map>
</APILoader>
</div>
);
export default Demo;
使用 Provider
import React from 'react';
import { useRef, useEffect, useState } from 'react';
import { Map, APILoader, useMap, Provider, useLabel } from '@uiw/react-baidu-map';
const Example = () => {
const [zoom, setZoom] = useState(15)
const divElm = useRef(null);
const { map, setContainer } = useMap({
zoom: 9,
widget: ['GeolocationControl', 'NavigationControl']
});
const { label } = useLabel({ map,
content: '徐泾镇',
position: { lng: 121.436256, lat: 31.246926 },
onClick: () => {
console.log('点击事件!');
}
});
useEffect(() => {
if (map) {
// 启用滚轮放大缩小,默认禁用
map.setZoom(zoom);
}
}, [zoom, map]);
useEffect(() => {
if (divElm.current) {
setContainer(divElm.current);
}
}, [divElm.current]);
let counts = zoom || 15;
return (
<>
<button onClick={() => setZoom(counts-1)}>-</button>
<span>{zoom || 15}</span>
<button onClick={() => setZoom(counts+1)}>+</button>
<div ref={divElm} style={{ height: 350 }} />
</>
)
}
const Demo = () => (
<div style={{ width: '100%' }}>
<APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
<Provider>
<Example />
</Provider>
</APILoader>
</div>
);
export default Demo;
