I am trying to show multiple routes on google map but It is showing only one. Can you please what I am doing wrong?
<div class="searchmap" style="float:left;margin-left:1%" id="map"></div>
var map = null;
var markerPoints = [];
var directionDisplay;
var directionsService = new google.maps.DirectionsService();
function initialize()
{
directionsDisplay = new google.maps.DirectionsRenderer();
map = new google.maps.Map(document.getElementById("map"), {scrollwheel:false, mapTypeId: google.maps.MapTypeId.ROADMAP, mapTypeControl: false, streetViewControl: false, center:new google.maps.LatLng(19.0759837, 72.87765590000004), zoom:13});
directionsDisplay.setMap(map);
}
function calcRoute(flat, flng, tlat, tlng)
{
var start = new google.maps.LatLng(flat, flng);
var end = new google.maps.LatLng(tlat, tlng);
var request = {
origin:start,
destination:end,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsDisplay = new google.maps.DirectionsRenderer({
suppressMarkers: false,
suppressInfoWindows: true
});
directionsDisplay.setMap(map);
directionsService.route(request, function(result, status) {
console.log(result);
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(result);
}
});
}
calcRoute("19.210430", "72.843422", "19.109858", "72.878433");
calcRoute("19.228977", "72.856812", "19.117302", "72.884041");
Can you please let me know what I am doing wrong?
