I'm trying to calculate the total distance for a route with a single waypoint in it, but somehow my code only returns the distance to the first waypoint instead of the total distance.
Here's my code:
function calcRoute(homebase,from,to,via){
var start = from;
var end = to;
var wypt = [ ];
wypt.push({
location:via,
stopover:true});
var request = {
origin:start,
destination:end,
waypoints:wypt,
optimizeWaypoints: true,
travelMode: google.maps.DirectionsTravelMode.DRIVING,
unitSystem: google.maps.DirectionsUnitSystem.METRIC
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
var distance = response.routes[0].legs[0].distance.text;
var time_taken = response.routes[0].legs[0].duration.text;
var calc_distance = response.routes[0].legs[0].distance.value;
}
});
}
The reason you only get the distance for legs[0] is because that is what your code is calculating. You need to sum up the distances of all the legs:

I'am trying to create a web app with google map direction API,In a variablesummaryPanel.innerHTMLContains the details regarding the address and distance.I required to use distance for other calculations ,so how can i access the variable,can we access the variable from the angular controller?
script.js
function initMap() {
var directionsService = new google.maps.DirectionsService;
var directionsDisplay = new google.maps.DirectionsRenderer;
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 6,
center: {lat: 41.85, lng: -87.65}
});
directionsDisplay.setMap(map);
document.getElementById('submit').addEventListener('click', function() {
calculateAndDisplayRoute(directionsService, directionsDisplay);
});
}
function calculateAndDisplayRoute(directionsService, directionsDisplay) {
var waypts = [];
var checkboxArray = document.getElementById('waypoints');
for (var i = 0; i < checkboxArray.length; i++) {
if (checkboxArray.options[i].selected) {
waypts.push({
location: checkboxArray[i].value,
stopover: true
});
}
}
directionsService.route({
origin: document.getElementById('start').value,
destination: document.getElementById('end').value,
waypoints: waypts,
optimizeWaypoints: true,
travelMode: 'DRIVING'
}, function(response, status) {
if (status === 'OK') {
directionsDisplay.setDirections(response);
var route = response.routes[0];
var summaryPanel = document.getElementById('directions-panel');
summaryPanel.innerHTML = '';
// For each route, display summary information.
for (var i = 0; i < route.legs.length; i++) {
var routeSegment = i + 1;
summaryPanel.innerHTML += '<b>Route Segment: ' + routeSegment +
'</b><br>';
summaryPanel.innerHTML += route.legs[i].start_address + ' to ';
summaryPanel.innerHTML += route.legs[i].end_address + '<br>';
summaryPanel.innerHTML += route.legs[i].distance.text + '<br><br>';
console.log(summaryPanel.innerHTML);//Variable required to access
}
} else {
window.alert('Directions request failed due to ' + status);
}
});
}
Using jQuery:
var htmlString = $(summaryPanel).html();
Then you'll have to parse whatever htmlString comes out to, but it will have what you're looking for.

}
});
}
above code works fine.But when I changed the part below,it gives me error code "Directions request failed due to zero_results".because of it can not find this coordinat (36.9165612, 34.895210200000065) in map.But actually I am getting this coordinats another google api.so this coordinat exists.Even it finds the address in google map https://www.google.com.tr/maps/place/36.9165612,+34.895210200000065/data=!4m2!3m1!1s0x0:0x0?sa=X&ved=0ahUKEwiB6OT03JjNAhWLLMAKHZrIApgQ8gEIGjAA
lastly when I change to coordinat to (41.85, -87.65), it works fine coz it finds the address.Many less coordinats works like this.
I want to find all coordinats in google maps.
How can I solve this problem?
var waypts = [];
var checkboxArray = document.getElementById('waypoints');
for (var i = 0; i < checkboxArray.length; i++) {
if (checkboxArray.options[i].selected) {
waypts.push({
location: new google.maps.LatLng(36.9165612, 34.895210200000065),
stopover: true
});
}
}
It may not find an address from a lat and lng. You have to consider it.

I need to display the results of a distance matrix request without geocoding. The problem is my locations are too close together and thus the resultant geocoded addresses are the same.
If I could display the results with the variable names or even the original lat/lon coordinate pairs I would be able to distinguish between the locations.
I checked the documentation for the Distance Matrix Response Elements and I did not see this functionality.
The javascript is below.
function initMap() {
var bounds = new google.maps.LatLngBounds;
var markersArray = [];
var origin1 = {lat: 37.2692332704, lng: -81.7261622975};

});
var geocoder = new google.maps.Geocoder;

} else {

var destinationList = response.destinationAddresses;
var outputDiv = document.getElementById('output');
outputDiv.innerHTML = '';
var showGeocodedAddressOnMap = function(asDestination) {
var icon = asDestination ? destinationIcon : originIcon;
return function(results, status) {
if (status === google.maps.GeocoderStatus.OK) {
map.fitBounds(bounds.extend(results[0].geometry.location));

}));
} else {

}
};
};
for (var i = 0; i < originList.length; i++) {
var results = response.rows[i].elements;
//geocoder.geocode({'address': originList[i]},
//showGeocodedAddressOnMap(false));
for (var j = 0; j < results.length; j++) {
//geocoder.geocode({'address': destinationList[j]},
//showGeocodedAddressOnMap(true));
outputDiv.innerHTML += originList[i] + ' to ' + destinationList[j] +
': ' + results[j].distance.text + ' in ' +
results[j].duration.text + '<br>';
}
}
}
});
}
Thanks in advance.
The results are returned in the order requested.
origin1 - destination1
origin1 - destination2
origin1 - destination3
origin2 - destination1
---
origin3 - destination3
You can use your original request to identify the exact coordinates used to calculate the result.

This question already has an answer here:
Google Directions Service with Waypoints not working
(1 answer)
Closed 8 years ago.
I am trying to display a route with waypoints for a trip. I save all the coordinates to a MySQL varchar attribute and then pull it out with php and slice it up into an array so the two array elements fruits[0] and fruits[1] represent the start, the fruits[2] and fruits[3] represent the first waypoint, that is the second place visited and so on.
I am trying to display the route of the trip and it works perfectly if I don't use waypoints, that is, if I don't populate the waypts array with all points except start and finish.
This is my code
<style>
#map-canvas {
width: 100%;
height: 400px;
}
</style>
<script type="text/javascript">
var fruits = <?php echo json_encode($arr); ?>;
for (var i = 0; i < fruits.length; i+=2) {
//text += cars[i];
}
</script>
<script>
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var dbk = new google.maps.LatLng(fruits[0], fruits[1]);
var mapOptions = {
zoom: 11,
center: dbk,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
directionsDisplay.setMap(map);
calcRoute();
}
function calcRoute() {
var waypts = [];
for (var i = 2; i < fruits.length -2; i+=2) {
waypts.push(new google.maps.LatLng(fruits[i], fruits[i+1]));
};
var request = {
origin: new google.maps.LatLng(fruits[0], fruits[1]),
destination: new google.maps.LatLng(fruits[fruits.length-2],fruits[fruits.length-1] ),
waypoints: waypts,
optimizeWaypoints: true,
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
var route = response.routes[0];
var summaryPanel = document.getElementById("directions_panel");
summaryPanel.innerHTML = "";
// For each route, display summary information.
for (var i = 0; i < route.legs.length; i++) {
var routeSegment = i + 1;
summaryPanel.innerHTML += "<b>Route Segment: " + routeSegment + "</b><br />";
summaryPanel.innerHTML += route.legs[i].start_address + " to ";
summaryPanel.innerHTML += route.legs[i].end_address + "<br />";
summaryPanel.innerHTML += route.legs[i].distance.text + "<br /><br />";
}
} else {
alert("directions response "+status);
}
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
You need to use Directions Waypoints for the waypoints.
var waypts = [];
for (var i = 2; i < fruits.length -2; i+=2) {
