OverviewMapControl 缩略地图控件
缩略地图控件。你也可以使用 Map
组件 widget
属性来设置控件更方便。
import { OverviewMapControl, useOverviewMapControl } from '@uiw/react-baidu-map';
// 或者单独安装使用
import OverviewMapControl, { useOverviewMapControl } from '@uiw/react-baidu-map-overview-map-control';
基本用法
import React, { useState, useRef } from 'react';
import { Map, APILoader, OverviewMapControl } from '@uiw/react-baidu-map';
const Example = () => {
const [show, setShow] = useState(true);
return (
<div>
<button onClick={() => setShow(!show)}>
{show ? '关闭' : '开启'}
</button>
<Map zoom={13} style={{ height: 300 }}>
{show && (
<OverviewMapControl isOpen />
)}
<OverviewMapControl
isOpen
visiable={show}
offset={new BMap.Size(40, 40)}
anchor={BMAP_ANCHOR_TOP_RIGHT}
onViewChanged={() => {
console.log('onViewChanged ..')
}}
/>
</Map>
</div>
);
}
const Demo = () => (
<div style={{ width: '100%' }}>
<APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
<Example />
</APILoader>
</div>
);
export default Demo;
使用 hooks
overviewMapControl
, setGeolocationControl
import React from 'react';
import { useRef, useEffect, useState } from 'react';
import { Map, APILoader, Provider, useMap, useOverviewMapControl } from '@uiw/react-baidu-map';
const Example = () => {
const divElm = useRef(null);
const [show, setShow] = useState(true);
const { setContainer, map } = useMap();
const { overviewMapControl } = useOverviewMapControl({
map, anchor: BMAP_NAVIGATION_CONTROL_LARGE, visiable: show, isOpen: true,
});
useEffect(() => {
if (divElm.current && !map) {
setContainer(divElm.current);
}
}, [map]);
return (
<>
<button onClick={() => setShow(!show)}>
{show ? '关闭' : '开启'}
</button>
<div ref={divElm} style={{ height: '100%' }} />
</>
);
}
const Demo = () => (
<div style={{ width: '100%', height: '300px' }}>
<APILoader akay="eYpCTECSntZmw0WyoQ7zFpCRR9cpgHFG">
<Provider>
<Example />
</Provider>
</APILoader>
</div>
);
export default Demo;
