I have this code that allows the user to enter two cities, and shows the location of the given inputs. But what I want is to show as well the direction from the 1st city to the other. How to do that?
Here is my practice code:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 100% }
</style>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?key=AIzaSyBQ8OCC8En5vNHod25Ov3Qs5E1v7NPRSsg&sensor=true">
</script>
<script type="text/javascript">
var geocoder;
var map;
function initialize1() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 100.644),
zoom: 8,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
mapOptions);
}
function initialize() {
// add mapOptions here to the values in the input boxes.
var mapOptions = {
center: new google.maps.LatLng(-34.397, 100.644),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"),mapOptions);
geocoder = new google.maps.Geocoder();
addAddress(document.getElementById('from').value);
addAddress(document.getElementById('to').value);
}
function addAddress(place) {
var address = place;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert('Geocode was not successful for the following reason: ' + status);
}
});
}
</script>
</head>
<body>
From: <input id="from" type="text" name="From"><br>
To: <input id="to" type="text" name="To"><br>

Use the DirectionsService in the Google Maps API v3. Here is an example from the documentation:
https://google-developers.appspot.com/maps/documentation/javascript/examples/directions-simple
and with text directions:
https://google-developers.appspot.com/maps/documentation/javascript/examples/directions-panel
if you mean the "location" means the address you can use the direction renderer like below to get the direction.
First of all store the location address of the two markers into the two text boxes if you want to display the to and from address with id's #from and #destination then follow the below code
$("#find").click(function () {
starting = $("#from").val();
finishing = $("#destination").val();
$("#map").gmap3(
{
action: 'getRoute',
options: {
origin: starting,
destination: finishing,
travelMode: google.maps.DirectionsTravelMode.DRIVING
},
callback: function (results) {
if (!results) {
alert("returning")
return
};
$(this).gmap3(
{
action: 'addDirectionsRenderer',
options: {
preserveViewport: true,
draggable: false,
directions: results
}
}
);
}
})
})
Explanation : At first I created two markers of different locations and different data then after the dragend of any marker there will be infowindow that shows the address and two buttons start and finish. I think you have done upto this part .
So after this I used two text boxes which will be filled according to the start button or finish button clicked .
After this if the user clicks the find button this text boxes values are used to find the direction between the two markers
Note: "here you can any marker for from or to only difference you have to maintain is to change the button clicked that is start or finish ....."
"You can even directly give the address in the text boxes and find the directions between them"
Here for whole manipulation I used gmap3 here is the code below that might help you
<script type="text/javascript">
window.onload = clear;
function clear() {
$("#from").val(null)
$("#destination").val(null)
}
$(document).ready(function () {
var starting = "";
var finishing = "";
$("#find").click(function () {
starting = $("#from").val();
finishing = $("#destination").val();
$("#map").gmap3(
{
action: 'getRoute',
options: {
origin: starting,
destination: finishing,
travelMode: google.maps.DirectionsTravelMode.DRIVING
},
callback: function (results) {
if (!results) {
alert("returning")
return
};
$(this).gmap3(
{
action: 'addDirectionsRenderer',
options: {
preserveViewport: true,
draggable: false,
directions: results
}
}
);
}
})
})
$("#map").gmap3({
action: 'addMarkers',
markers: [ //markers array
{lat: 22.74, lng: 83.28, data: 'madhu' },
{ lat: 17.74, lng: 82.28, data: 'raghu' }
],
map: { // this is for map options not for any markers
center: [17.74, 83.28],
zoom: 5
},
marker: {
options: {
draggable: true
},
events: {// marker events
dragend: function (marker, event, data) {
var contentString = '<div id="main content">'
+ '<input type="button" id="start" value="start" />'
+ '<input type="button" id="finish" value="finish" />'
+ '</div>';
//get address on click event
$(this).gmap3({
action: 'getAddress',
latLng: marker.getPosition(),
callback: function (results) {
var map = $(this).gmap3('get'),
infowindow = $(this).gmap3({ action: 'get', name: 'infowindow' })
if (infowindow) {
content = results && results[1] ? results && results[1].formatted_address : 'no address';
infowindow.open(map, marker);
infowindow.setContent(content + contentString);
}
else {
content = results && results[1] ? results && results[1].formatted_address : 'no address';
$(this).gmap3({
action: 'addinfowindow',
anchor: marker,
options: { content: content + contentString },
events: {
domready: function () {
$("#start").click(function () {
alert("start clicked " + content);
$("#from").val(content);
starting = content;
check();
})
$("#finish").click(function () {
alert("finish clicked " + content);
$("#destination").val(content);
finishing = content;
})
}
}
});
}
}
});
},
}
},
});
});
</script>
here is the html part for the above
<div id="headinput">
<input type="text" value="enter from" id="from" />
<input type="text" value="enter destination" id="destination" />
<input type="button" value="find" id="find" />
</div>
<br />
<div id ="map"style="width: 100%; top: auto; left: auto; position: relative; height: 600px; float:left" ></div>
This is perfectly worked one I checked it in firefox browser........:D

I am trying to capture the location of a draggable waypoint in a google direction javascript API, so I can save it the database and load the same directions later.
I try to acces the waypoint's location via result.routes[0].legs[0].via_waypoints[0], which offers me nothing useful - lat and lng object are "empty" instead of containing geolocation (same goes for result.routes[0].legs[0].via_waypoint[0].location.
I have a remark in my code to access waypoint's geolocation via result.routes[0].legs[0].via_waypoints[0].k and result.routes[0].legs[0].via_waypoints[0].D, which does not work. I found on stackoverflow a similar question from 2011, which suggests to use location.wa and location.ya, which also does not work.
I've added a code snippet, you should replace #YOURAPIKEY# with your Google API key for the example to work. It's a slightly modified example from Google's documentation
Can anyone help me with this?
Each leg of your route is a set of steps and in the case you submitted, each leg corresponds to directions between one of your stops (origin, waypoints, destination).
leg[0] from Perth to Adelaide
leg[1] from Adelaide to Broken Hill
leg[2] from Broken Hill to Sydney
So you won't have anything in the via_waypoints prop.
You need to set stopover: false in your waypoints if you want them not considered as a real stop. Then you will get the via_waypoints property populated for each leg (if more than one).
waypoints: [{
location: 'Adelaide, SA',
stopover: false
}, {
location: 'Broken Hill, NSW',
stopover: false
}],
You can then iterate though via_waypoints and get the coordinates.
lat and lng are methods, not properties, so you need to call them, for example:
let firstWaypointLat = result.routes[0].legs[0].via_waypoints[0].lat();
Example below on how to get the waypoints coordinates:
function initMap() {
var map = new google.maps.Map(document.getElementById('map-canvas'), {
zoom: 4,
center: {
lat: -24.345,
lng: 134.46
} // Australia.
});
var directionsService = new google.maps.DirectionsService;
var directionsDisplay = new google.maps.DirectionsRenderer({
draggable: true,
map: map,
panel: document.getElementById('right-panel')
});
directionsDisplay.addListener('directions_changed', function() {
computeTotalDistance(directionsDisplay.getDirections());
});
displayRoute('Perth, WA', 'Sydney, NSW', directionsService,
directionsDisplay);
}
function displayRoute(origin, destination, service, display) {
service.route({
origin: origin,
destination: destination,
waypoints: [{
location: 'Adelaide, SA',
stopover: false
}, {
location: 'Broken Hill, NSW',
stopover: false
}],
travelMode: 'DRIVING',
avoidTolls: true
}, function(response, status) {
if (status === 'OK') {
display.setDirections(response);
} else {
alert('Could not display directions due to: ' + status);
}
});
}
function computeTotalDistance(result) {
let leg = result.routes[0].legs[0];
for (let i=0; i<leg.via_waypoints.length; i++) {
console.log('Waypoint ' + i + ' coords: ' + leg.via_waypoints[i].lat() + ', ' + leg.via_waypoints[i].lng());
}
}

Nested AJAX call are used to get foursquare image URL.
First AJAX call is to derive venue ID from foursquare API and used in 2nd AJAX call to get image URL. Said image URL is used to render venue image in Google Map's Infowindow after each marker is clicked.

Accurately render each venue image in infowindow when each marker is clicked once.
When map is loaded, the first click on one marker did not render venue image in infowindow until it is clicked the second time. Chrome's developer tool console showed "net::ERR_FILE_NOT_FOUND".
When a second marker is clicked, image from first marker is rendered in infowindow until it is clicked the second time.
I appreciate any input on this as I am new to Javascript. Thanks in advance!
Infowindow setcontent was fired before nested AJAX call was completed. Therefore jQuery deferreds was used (with when & then statement) to ensure nested JSON is complete before setting content in infowindow.
Code as follow;

Location code is not working here.In fiddle it is working see link below

I am using angular-maps to create a map, with a list of markers.
I have a problem displaying the markers. I have no errors though.
Here is my code:
Controller
var app = angular.module('mapController', []);
app.service('Map', function($q) {
this.init = function() {
var options = {
center: new google.maps.LatLng(45.7154289, 4.9317724),
zoom: 14,
disableDefaultUI: true
}
this.map = new google.maps.Map(
document.getElementById("map"), options
);
this.places = new google.maps.places.PlacesService(this.map);
var markers = [{
"title": 'Capgemini',
"lat": '45.7154289',
"lng": '4.9317724',
"description": 'Capgemini'
}];
var defaultMarkerColor = 'ff0000';
var pinImage = new google.maps.MarkerImage("http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|" + defaultMarkerColor);
// marker object for the marker
var marker = new google.maps.Marker({
position: google.maps.LatLng(markers[0].lat,markers[0].lng),
map: this.map,
title: markers[0].title,
animation: google.maps.Animation.DROP,
icon: pinImage
});
}
this.search = function(str) {
var d = $q.defer();
this.places.textSearch({query: str}, function(results, status) {
if (status == 'OK') {
d.resolve(results[0]);
}
else d.reject(status);
});
return d.promise;
}
this.addMarker = function(res) {
if(this.marker) this.marker.setMap(null);
this.marker = new google.maps.Marker({
map: this.map,
position: res.geometry.location,
animation: google.maps.Animation.DROP
});
this.map.setCenter(res.geometry.location);
}
});
app.controller('mapController', function($scope, Map) {
$scope.place = {};
$scope.search = function() {
$scope.apiError = false;
Map.search($scope.searchPlace)
.then(
function(res) { // success
Map.addMarker(res);
$scope.place.name = res.name;
$scope.place.lat = res.geometry.location.lat();
$scope.place.lng = res.geometry.location.lng();
},
function(status) { // error
$scope.apiError = true;
$scope.apiStatus = status;
}
);
}
$scope.send = function() {
alert($scope.place.name + ' : ' + $scope.place.lat + ', ' + $scope.place.lng);
}
Map.init();
});
and the HTML :
<ion-content ng-controller="mapController" style="margin-top: 25px">
<div class="container">
<div id="map" libraries="places" data-tap-disabled="true"></div>
<form name="searchForm" novalidate
ng-submit="search()">
<div class="input-group">
<input name="place" type="text" class="form-control"
ng-model="searchPlace" required autofocus />
<br>
<span class="input-group-btn">
<button class="btn btn-primary"
ng-disabled="searchForm.$invalid">Search</button>
</span>
</div>
</form>
</div>
The map shows up correctly, and centered on the coordinates I chose, but without a marker.
I would appreciate any help.
Hi took me sometime to put in place the fiddle... :)
I made this changes to make it work:
The markers:
var markers = [{
"title": 'Capgemini',
"lat": 45.7154289,
"lng": 4.9317724,
"description": 'Capgemini'
}];
And then the marker definition
var marker = new google.maps.Marker({
position:{lat: markers[0].lat, lng: markers[0].lng},
map: this.map,
title: markers[0].title,
animation: google.maps.Animation.DROP,
icon: pinImage
});
the easiest way is to use numbers for the coords.
here you can find the fiddle
it isn't super clean and it is lot of debug stuff and most important if you can initialize and see the map you don't really need it.
hope this help
