Easy Code Stuff: Getting The Direction Between Two Locations Using Google MAP API

In this article I'm going to show guys to get the direction between two locations. In-order to do that I have created a simple html page consisting four text fields to enter the from locations and to locations latitude and longitude. You can enter the locations latitude and longitudes of from and to locations and click the "Get Direction" button. After clicking the button you will get the direction.

Have a look on the code. It's simply created using Html and JavaScript.

  <script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?sensor=false&libraries=geometry,places"></script>
  <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.10.1.min.js"></script>
 </head>
 <body> 
  <div>
   <strong>From Location</strong><br/>
   <span>Latitude : </span>
   <input type="text" id="fromLat"/>
   <span>Longitude : </span>
   <input type="text" id="fromLng"/>
   <br/><br/>

   <strong>To Location</strong><br/>
   <span>Latitude : </span>
   <input type="text" id="toLat"/>
   <span>Longitude : </span>
   <input type="text" id="toLng"/>
   <br/><br/>

   <input type="button" value="Get Direction" onclick="getDirection()"/>
   <br/><br/>
   <div id="direction"></div>
  </div>
  
  <script type="text/javascript">

      function getDirection() {
          var fromLocation = new google.maps.LatLng($("#fromLat").val(), $("#fromLng").val());
          var toLocation = new google.maps.LatLng($("#toLat").val(), $("#toLng").val());
          var service = new google.maps.DistanceMatrixService();
          service.getDistanceMatrix({
              origins: [fromLocation],
              destinations: [toLocation],
              travelMode: google.maps.TravelMode.DRIVING,
              unitSystem: google.maps.UnitSystem.METRIC,
              avoidHighways: false,
              avoidTolls: false
          }, callback_direction);
      }

      function callback_direction(response, status) {
          if (status != google.maps.DistanceMatrixStatus.OK) {
              alert('Error was: ' + status);
          } else {
              var origins = response.originAddresses;
              var destinations = response.destinationAddresses;
              var str = '';

              for (var i = 0; i < origins.length; i++) {
                  var results = response.rows[i].elements;
                  if (results[0].status != 'ZERO_RESULTS') {
                      for (var j = 0; j < results.length; j++) {
                          str += origins[i] + '<strong> to </strong>' + destinations[j] + '<strong> : </strong>' + results[j].distance.text + '<strong> in </strong>' + results[j].duration.text + '<br/>';
                      }
                  } else {
                      str = 'No Direction Found.';
                  }
              }

              $("#direction").html(str);
          }
      }
  </script>
 </body>
</html>

Just check the code in browser, you will get the following output.

When you are getting the direction between two locaions, you must specify the mode of the travel. Following are the travel modes supported by google.

google.maps.TravelMode.DRIVING (Default) indicates standard driving directions using the road network.
google.maps.TravelMode.BICYCLING requests bicycling directions via bicycle paths & preferred streets.
google.maps.TravelMode.TRANSIT requests directions via public transit routes.
google.maps.TravelMode.WALKING requests walking directions via pedestrian paths & sidewalks.
