Google Map Point A to Point B Direction Example

Hello devs,

In this tutorial, I will show you an example of how we can draw a google map from point a to point b with a direction route. If you don't know google maps api draw route between multiple points then this example is for you. I will use direction api to draw this map with to point.

So from this direction map example, I will draw line from point a to point b using latitude and longitude with the static value. You can make it dynamic with your latitude and longitude. So from this example you will learn how to draw a google map with two point with polygonal line. 

See the example preview:

First create a div with this id like:

 

And use this javascript api code to generate this above map:

function initMap() {
    var pointA = new google.maps.LatLng(51.7519, -1.2578),
        pointB = new google.maps.LatLng(50.8429, -0.1313),
        myOptions = {
            zoom: 7,
            center: pointA
        },
        map = new google.maps.Map(document.getElementById('map-canvas'), myOptions),
        // Instantiate a directions service.
        directionsService = new google.maps.DirectionsService,
        directionsDisplay = new google.maps.DirectionsRenderer({
            map: map
        }),
        markerA = new google.maps.Marker({
            position: pointA,
            title: "point A",
            label: "A",
            map: map
        }),
        markerB = new google.maps.Marker({
            position: pointB,
            title: "point B",
            label: "B",
            map: map
        });

    // get route from A to B
    calculateAndDisplayRoute(directionsService, directionsDisplay, pointA, pointB);

}



function calculateAndDisplayRoute(directionsService, directionsDisplay, pointA, pointB) {
    directionsService.route({
        origin: pointA,
        destination: pointB,
        avoidTolls: true,
        avoidHighways: false,
        travelMode: google.maps.TravelMode.DRIVING
    }, function (response, status) {
        if (status == google.maps.DirectionsStatus.OK) {
            directionsDisplay.setDirections(response);
        } else {
            window.alert('Directions request failed due to ' + status);
        }
    });
}

initMap();
