Google मानचित्र पर कई मार्ग प्रदर्शित करें

Question

मैं Google मानचित्र पर कई मार्ग दिखाने की कोशिश कर रहा हूं लेकिन यह केवल एक दिखा रहा है। क्या आप कृपया क्या कर सकते हैं मैं गलत कर रहा हूँ?

<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"); 

तुम मुझे जानते हो मैं गलत क्या कर रहा हूँ तो कृपया कर सकते हैं?

Answer 2

आपका directionsDisplay चर google.maps.DirectionsRenderer() का एक उदाहरण है और यह एक समय में केवल एक दिशा निर्देश रख सकता है। यदि आप एक से अधिक मार्ग प्रदर्शित करना चाहते हैं, तो आपको कई google.maps.DirectionsRenderer() की आवश्यकता है।
