Using Longitude/Latitude as Waypoint
I'm trying to use the longitude latitude as a waypoint in my google maps and cant seem to get it working.
Here's how I have my values pushed
waypts_mtlsheloc.push({
location: (45.658197,-73.636333), //I don't think I'm supposed to write this like that. But can't find the right way.
stopover: true
})
And then try to modify my line like this
service.route({
origin: latlng_mtlsheloc[0],
destination: latlng_mtlsheloc[latlng_mtlsheloc.length - 1],
waypoints:waypts_mtlsheloc,
travelMode: google.maps.DirectionsTravelMode.DRIVING
}, function(result, status) {
console.log(status)
if (status == google.maps.DirectionsStatus.OK) {
path = path.concat(result.routes[0].overview_path);
line_mtlsheloc.setPath(result.routes[0].overview_path);
}
});
But it gives me an error "Error in property [waypoint]", I've tried different methods of writing down the location, but can't seem to find the right one.

To use a latitude and longitude as a waypoint, it must be a google.maps.LatLng object (the documentation says a string or a LatLng; string is an address, LatLng is geographic coordinates)
waypts_mtlsheloc.push({
location: new google.maps.LatLng(45.658197,-73.636333),
stopover: true
})
code snippet:
var directionDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
function initialize() {
directionsDisplay = new google.maps.DirectionsRenderer();
var chicago = new google.maps.LatLng(41.850033, -87.6500523);
var myOptions = {
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: chicago
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
directionsDisplay.setMap(map);
calcRoute();
}
function calcRoute() {
var request = {
origin: "1521 NW 54th St, Seattle, WA 98107 ",
destination: "San Diego, CA",
waypoints: [{
location: new google.maps.LatLng(42.496403, -124.413128),
stopover: false
}],
optimizeWaypoints: true,
travelMode: google.maps.DirectionsTravelMode.WALKING
};
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);
