如何更改 reactJS Leaflet 中的按钮位置?
How to change button position in reactJS Leaflet?
我想移动地图上的BasemapGallery Leaflet 和GeoSearch Leaflet 的位置,但是编码时不知道如何移动,这里是:
- BasemapGallery 传单想要向右移动,并且
- GeoSearch 传单要向左移动。

这是我的代码以及我需要更改的代码:
import { React, useState, useEffect } from 'react'
import {
LayersControl,
MapContainer,
TileLayer,
Marker,
Popup,
useMapEvents,
} from 'react-leaflet'
import List from '../Component/List'
import L from 'leaflet'
import SearchControl from './SearchControl'
const { BaseLayer } = LayersControl
function LocationMarker() {
const [position, setPosition] = useState(null)
const map = useMapEvents({
locationfound(e) {
setPosition(e.latlng)
map.flyTo(e.latlng, map.getZoom())
},
})
return position === null ? null : (
<Marker position={position}>
<Popup>Location Me</Popup>
</Marker>
)
}
function MyLocationMe() {
const [map, setMap] = useState(null)
const [position, setPosition] = useState(null)
useEffect(() => {
if (!map) return
L.easyButton('fa-map-marker', () => {
map.locate().on('locationfound', function (e) {
setPosition(e.latlng)
map.flyTo(e.latlng, map.getZoom())
})
}).addTo(map)
}, [map])
return (
<div className="flex ml-auto">
<List />
<div className="w-4/5">
<MapContainer
center={{ lat: 51.505, lng: -0.09 }}
zoom={20}
style={{ height: '100vh' }}
whenCreated={setMap}
>
<SearchControl className="MarkerIcon" />
<LayersControl>
<BaseLayer checked name="OpenStreetMap">
<TileLayer

url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png "
/>
</BaseLayer>
</LayersControl>
<LocationMarker />
</MapContainer>
</div>
</div>
)
}
export default MyLocationMe
控件应该有一个 position
属性:
<SearchControl className="MarkerIcon" position="topright" />
和
<LayersControl position="topleft">
<BaseLayer checked name="OpenStreetMap">
<TileLayer

/>
</BaseLayer>
