How can HTML5 geolocation be utilized to provide real-time latitude and longitude coordinates for integration with the Google Maps API?

I am currently working on a project where I need to dynamically fetch longitude and latitude values from the browser geolocation and then include them in the options array for the Google Maps API. Here is the code snippet I am using:

function initMap(){

if (navigator.geolocation){
    navigator.geolocation.getCurrentPosition(position =>{
        long = position.coords.longitude;
        lat = position.coords.latitude;

        var options = {
            zoom: 12,
            center: {lat: ${lat},${long}}
        }

    var map = new google.maps.Map(document.getElementById('map'), options);
});

}

Unfortunately, I am facing an issue where the variables I have set up for the latitude and longitude values are not being accepted by the options > center tag. I have tried different approaches but no luck so far. Can someone guide me on how to solve this problem or if there is something I might be overlooking?

Appreciate any help!

Answer №1

Here, the usage is incorrect.

Edit

var settings = {
            zoom: 12,
            center: {lat: ${latitude},${longitude}}
        }

Replace with

var settings = {
                zoom: 12,
                center: { lat: latitude, lng: longitude }
           }

The final code will appear as follows...

function initializeMap() {
            if (navigator.geolocation) {
                navigator.geolocation.getCurrentPosition(position => {
                    longitude = position.coords.longitude;
                    latitude = position.coords.latitude;

                    var settings = {
                        zoom: 12,
                        center: { lat: latitude, lng: longitude }
                    }

                    var map = new google.maps.Map(document.getElementById('map'), settings);
                });

            }
        }
