Google Maps click event on route
I'm trying to draw a circle wherever I click on the route. I looked for a solution on how to make a route clickable and couldn't find anything helpful... Below is my code. I get no errors when I click on the route but no circle is created.
directionsDisplay = new google.maps.DirectionsRenderer(rendererOptions);
//direction service request here...
google.maps.event.addListener(directionsDisplay, 'click', function(event) {
var routeClick = new google.maps.Circle({
center: event.latLng, //center where you click
radius: 500,
strokeColor: "#0000FF",
strokeOpacity: 0.8,
strokeWeight: 2,
fillColor: "#0000FF",
fillOpacity: 0.4
});
routeClick.setMap(map);
});
UPDATE:
Working code to create your own directions polyline based on Geocodezip's script http://www.geocodezip.com/v3_directions_custom_iconsC.html and official API example https://developers.google.com/maps/documentation/javascript/examples/elevation-paths
// Draw the path
function drawPath(path) {
// Display a polyline of the elevation path.
var pathOptions = {
path: path,
strokeColor: '#0000CC',
strokeWeight: 5,
opacity: 0.4,
map: map
}
routePolyline = new google.maps.Polyline(pathOptions);
}
then in the directionService request I added
directionService.route(request, function(result, status) {
var path = result.routes[0].overview_path;
drawPath(path);
});
There is no 'click' event on the DirectionsRenderer
you can render the polyline yourself and add a click event listener to it or add a click listener to the map.

code snippet:
var infowindow = new google.maps.InfoWindow();
var directions = new google.maps.DirectionsService();
var renderer = new google.maps.DirectionsRenderer({
suppressPolylines: true,
infoWindow: infowindow,
});
var map;
function initialize() {
var mapOptions = {
zoom: 13,
center: new google.maps.LatLng(40.7482333, -73.8681295),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'), mapOptions);
google.maps.event.addDomListener(document.getElementById('go'), 'click',
route);
var input = document.getElementById('from');
var autocomplete = new google.maps.places.Autocomplete(input);
autocomplete.bindTo('bounds', map);
route();
}
function route() {
var request = {
origin: document.getElementById('from').value,
destination: '51 St, New York, NY 10022, USA',
travelMode: google.maps.DirectionsTravelMode.WALKING
};
var panel = document.getElementById('panel');
panel.innerHTML = '';
directions.route(request, function(response, status) {
if (status == google.maps.DirectionsStatus.OK) {
renderer.setDirections(response);
renderer.setMap(map);
renderer.setPanel(panel);
renderDirectionsPolylines(response);
console.log(renderer.getDirections());
} else {
renderer.setMap(null);
renderer.setPanel(null);
}
});
}
var polylineOptions = {
strokeColor: '#C83939',
strokeOpacity: 1,
strokeWeight: 4
};
var polylines = [];
function renderDirectionsPolylines(response) {
for (var i=0; i<polylines.length; i++) {
polylines[i].setMap(null);
}
var legs = response.routes[0].legs;
for (i = 0; i < legs.length; i++) {
var steps = legs[i].steps;
for (j = 0; j < steps.length; j++) {
var nextSegment = steps[j].path;
var stepPolyline = new google.maps.Polyline(polylineOptions);
for (k = 0; k < nextSegment.length; k++) {
stepPolyline.getPath().push(nextSegment[k]);
}
polylines.push(stepPolyline);
stepPolyline.setMap(map);
// route click listeners, different one on each step
google.maps.event.addListener(stepPolyline, 'click', function(evt) {
infowindow.setContent("you clicked on the route<br>" + evt.latLng.toUrlValue(6));
infowindow.setPosition(evt.latLng);
infowindow.open(map);
})
}
