In this tutorial, we’ll be learning about how to draws a route between two points. We’ll be using Google Maps Directions API in our application.
Create a new Google Map API Key from the API console using the steps demonstrated in this tutorial.
CSS
You can define map height and width under #map section
Add this code in your head section of the html file
<style>
#map {
height: 100%;
}
html, body {
height: 100%;
margin: 0;
padding: 0;
}
</style>
Script
<script>
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: {lat: 17.3483, lng: 78.3915}, //Default location to show on the map
mapTypeId: 'terrain'
});
//Two coordinates to draw a path
var flightPlanCoordinates = [
{lat: 17.4483, lng: 78.3915},
{lat: 17.291, lng: 78.821}
];
//Draw a simple Polyline
var flightPath = new google.maps.Polyline({
path: flightPlanCoordinates,
geodesic: true,
strokeColor: '#FF0000',
strokeOpacity: 1.0,
strokeWeight: 2
});
flightPath.setMap(map);
}
</script>
Use your API key here, that you created in the google console.
If you are not created follow this link to create, it's a simple process.
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
</script>
Body
<body>
<div id='map'>
</body>
Result
The content looks real with valid information. Good Work
