Display attributes for Selected Store

Listen to the Selected Store and pass it to a component where you would like to display your stores attributes.

1. MVC Object
2. Set SelectedStore State
3. Create an InfoBox Component
4. Result

MVC Object

The Woosmap Store Locator JS API provide a class called MVCObject() implementing the KVO mechanism, for Key Value Observing. Using it you can observe properties changes of an object.

The woosmap.TiledView handles the click event on all store markers and save the store clicked into property called selectedStore. As the TiledView extends the MVCObject this property is bindable. Therefore, to be aware that a user select a store on the Map, create a new MVCObject and bind it to this property on the TiledView.

Map.js

JavaScript

        const mapView = new window.woosmap.TiledView(map, conf.markersOptions);
const selectedStoreObserver = new window.woosmap.utils.MVCObject();
selectedStoreObserver.selectedStore_changed = () => {
    console.log(selectedStoreObserver.get('selectedStore'));
};
selectedStoreObserver.bindTo('selectedStore', mapView);

    

Set SelectedStore State

The purpose here is to create a state for the Map component to save the selected store. With useState hook, React can remember a state variable for us, making sure it gets passed into our component instance correctly.

Map.js

JavaScript

        const Map = () => {
    const [selectedStore, setSelectedStore] = useState()
    
    //in initMap()
    selectedStoreObserver.selectedStore_changed = () => {
        setSelectedStore(selectedStoreObserver.get('selectedStore'));
    };
}


    

Create an InfoBox Component

Now that you are able to collect and remember the selected store, you can create a component and pass in this state, so the component will update on selected store change. Create a new file components/InfoBox.js and build a component accepting the store as parameter.

components/InfoBox.js

JavaScript

        const Infobox = ({store}) => {
    return (
        <div className='infoBox' id={`infobox-${store.properties.store_id}`}>
            <div className="infoBox__storeName">{store.properties.name}</div>
            {store.properties.address && <div>
                <h4 className="infoBox__addressTitle">Address</h4>
                <div className="infoBox__addressLines">{store.properties.address.lines}</div>
                <div className="infoBox__addressCity">{store.properties.address.city}</div>
            </div>}
            {store.properties.contact && <div>
                <h4 className="infoBox__contactTitle">Contact</h4>
                <div className="infoBox__contactPhone">{store.properties.contact.phone}</div>
                <div className="infoBox__contactWebsite"><a href={store.properties.contact.website} target='_blank'>go
                    to website</a>
                </div>
            </div>}
        </div>
    );
};
export default Infobox;

    

You can also add a default return when no store is selected, which is the case before the user clicks on a marker.

JavaScript

        if (!store) {
    return (<div className="infoBox">Click on a Store Marker...</div>);
}

    

The infobox needs a few styling rules to display over the Map component correctly. Add the following CSS to the InfoBox.css file:

components/InfoBox.css

CSS

        .infoBox {
    display: inline-block;
    position: absolute;
    top: 0;
    left: 0;
    margin: 15px;
    padding: 15px;
    background-color: #FFF;
    border-radius: 4px;
    color: #1d1d1d;
    z-index: 1;
    box-shadow: 0 2px 5px rgba(0, 0, 0, 0.3);
    max-width: 300px;
}

    

Finally, in your Map component, add your newly created InfoBox with the state property store={selectedStore}.

Map.js

JavaScript

        import Infobox from "./components/InfoBox";
/*...*/
return (
    <div>
        <Infobox store={selectedStore}/>
        <div className='mapContainer' ref={mapContainerRef}/>
    </div>
);

    

Result

You have created a React app that uses Woosmap Store Locator JS API to render a map, display your stores on top of it, and let the user interacts with them to display relative attributes.

You can explore this example and other more complex in the Woosmap React examples GitHub repository.
