I'm a new leaflet learner with React typescript. Want to create a custom button on the map. On clicking the button a popup will appear. I saw many example but they are all based on older version and I also tried to create my own but no luck. The documentation also not providing much help. Even a functional custom control component is also very effective for my app. Any help on this will be much appreciated. Here is my code,
Custom button
import React, { Component } from "react";
import { useMap } from "react-leaflet";
import L, { LeafletMouseEvent, Map } from "leaflet";
class Description extends React.Component<{props: any}> {
createButtonControl() {
const MapHelp = L.Control.extend({
onAdd: (map : Map) => {
const helpDiv = L.DomUtil.create("button", ""); //how to pass here the button name and
//other property ?
//a bit clueless how to add a click event listener to this button and then
// open a popup div on the map
}
});
return new MapHelp({ position: "bottomright" });
}
componentDidMount() {
const { map } = this.props as any;
const control = this.createButtonControl();
control.addTo(map);
}
render() {
return null;
}
}
function withMap(Component : any) {
return function WrappedComponent(props : any) {
const map = useMap();
return <Component {...props} map={map} />;
};
}
export default withMap(Description);
The way I want to call it
<MapContainer
center={defaultPosition}
zoom={6}
zoomControl={false}
>
<Description />
<TileLayer

/>
<ZoomControl position={'topright'}/>
</MapContainer>
