Directions in Google Maps stopped working, when I added geolocation - javascript

I'm trying to make Google Maps directions work with geolocation (using samples provided by Google Maps). Alone both work, but when combined there is a problem, that the map won't show the path (however autocomplete works fine).
function initMap() {
if (navigator.geolocation){
navigator.geolocation.getCurrentPosition(function(position){
var map = new google.maps.Map(document.getElementById('map'), {
mapTypeControl: false,
center: {lat:position.coords.latitude, lng:position.coords.longitude},
zoom: 10
});
var panorama = new google.maps.StreetViewPanorama(
document.getElementById('pano'), {
position: {lat:position.coords.latitude, lng:position.coords.longitude},
pov: {
heading: 34,
pitch: 10
}
});
var usermarker = new google.maps.Marker({
position: {lat:position.coords.latitude, lng:position.coords.longitude},
draggable: true,
map: map,
icon: 'http://x3.cdn03.imgwykop.pl/c3201142/comment_aBtolaUIxKS7cvUnii43PWDPT3Lqduc2,w400.jpg',
});
// test marker
var marker2 = new google.maps.Marker({
position: {lat:50.671064, lng:17.926138},
draggable: true,
map: map,
icon: 'http://emojipedia-us.s3.amazonaws.com/cache/1e/4d/1e4d8093e7011575d9266598a06d8ecb.png',
});
});
new AutocompleteDirectionsHandler(map);
}
/**

//everything works until this moment

});

if (!place.place_id) {
window.alert("Please select an option from the dropdown list.");

I've experimented with putting the path making part in various positions and finaly got it working. #Jaromanda X - thanks for the idea :)

Google Maps Marker not shown - autocomplete

I have this project with Google Maps API. Everything works perfectly except that Google Marker added through an input value is not showing. I have inputs, of which two are origin and destination respectively, with direction both show perfectly but the third input which is added later doesn't show. I have a different function to take care of it though.
<input type="text" class="form-control" id="origin_input" name="origin_input">
<input type="text" class="form-control" id="destination_input" name="destination_input">
<input type="text" class="form-control" id="stopOver">
And here is my JavaScript for the Google Map:
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
mapTypeControl: false,
center: {
lat: 7.946527,
lng: -1.023194

var stopOver = new google.maps.places.Autocomplete(document.getElementById('stopOver'));
google.maps.event.addListener(stopOver, 'place_changed', function() {
var coord = stopOver.getPlace().geometry.location;
console.log(coord);
window.post = coord;
});
var marker = new google.maps.Marker({

You have three issues with your addStopover function:
you are using the wrong map variable
the icon doesn't exists
you are creating the marker before the place_changed event fires and it's callback function runs
working version of the function:
function addStopOverMarker(map) {
var stopOver = new google.maps.places.Autocomplete(document.getElementById('stopOver'));
google.maps.event.addListener(stopOver, 'place_changed', function() {
var coord = stopOver.getPlace().geometry.location;
console.log(coord);
var marker = new google.maps.Marker({
position: coord,
map: map,
draggable: true,
visible: true
});
});

var directionsDisplay;
var directionsService;
var stepDisplay;
var markerArray = [];
var infoWindow;
var service;
var lat1 = 0;
var lng1;
function pre_initialize() {
var mapOptions = {
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function (position) {
var pos = new google.maps.LatLng(position.coords.latitude,position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: pos,
content: 'Current Location.'
});
map.setCenter(pos);
}, function () {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: The Geolocation service failed.';
} else {
var content = 'Error: Your browser doesn\'t support geolocation.';
}
var options = {
map: map,
position: new google.maps.LatLng(60, 105),
content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
function initialize() {
var mapOptions = {
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var addressfrom = document.getElementById("from").value;
var addressto = document.getElementById("to").value;
var geocoder = new google.maps.Geocoder();
var coords = new google.maps.LatLng(0, 0);
alert(lat1);
coords = geocoder.geocode({ 'address': addressfrom }, function (results, status) {
results[0].geometry.location.lat();
results[0].geometry.location.lng();
});
directionsService = new google.maps.DirectionsService();
// Create a renderer for directions and bind it to the map.
var rendererOptions = {
map: map
}
directionsDisplay = new google.maps.DirectionsRenderer(rendererOptions)
// Instantiate an info window to hold step text.
infoWindow = new google.maps.InfoWindow();
stepDisplay = new google.maps.InfoWindow();
calcRoute();
google.maps.event.addListenerOnce(map, 'bounds_changed', performSearch);

function callback(results, status) {

alert(status);
return;
}
for (var i = 0, result; result = results[i]; i++) {
createMarker(result);
}
}
function createMarker(place) {
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location,
icon:
{
// Star
path: 'M 0,-24 6,-7 24,-7 10,4 15,21 0,11 -15,21 -10,4 -24,-7 -6,-7 z',

google.maps.event.addListener(marker, 'click', function () {

alert(status);
return;
}
infoWindow.setContent(result.name);
infoWindow.open(map, marker);
});
});
}
function calcRoute() {
// First, remove any existing markers from the map.
for (var i = 0; i < markerArray.length; i++) {

}
// Now, clear the array itself.

directionsDisplay.setDirections(response);
showSteps(response);
}
});
}
function showSteps(directionResult) {
var myRoute = directionResult.routes[0].legs[0];
for (var i = 0; i < myRoute.steps.length; i++) {
var marker = new google.maps.Marker({

}
function attachInstructionText(marker, text) {
google.maps.event.addListener(marker, 'click', function () {
stepDisplay.setContent(text);
stepDisplay.open(map, marker);
});
}
</script>
Refer to the code below:
self.adjustPosition = function () {
var lat = 0, lng = 0;
if (self.nearbyPlaces().length == 0) {
return false;
}
for (var i = 0; i < self.nearbyPlaces().length; i++) {
lat += self.nearbyPlaces()[i].latitude;
lng += self.nearbyPlaces()[i].longitude;
}
lat = lat / self.nearbyPlaces().length;
lng = lng / self.nearbyPlaces().length;
self.map.setCenter(new window.google.maps.LatLng(lat, lng));
};

Not giving me directions

I might not be understanding how this works, but if I enter in #Model.name which would find an address (just make one up for your testing purposes) the following javascript should find me, find the destination and find me directions.
But it doesn't. Why doesn't it? There are no console errors.
function success(position) {
var s = document.querySelector('#status');
if (s.className == 'success') {
// not sure why we're hitting this twice in FF, I think it's to do with a cached result coming back
return;
}
s.innerHTML = "found you!";
s.className = 'success';
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcanvas';
mapcanvas.style.height = '400px';
mapcanvas.style.width = '560px';
document.querySelector('article').appendChild(mapcanvas);
var latlng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var directionsService = new google.maps.DirectionsService();
var directionsDisplay = new google.maps.DirectionsRenderer();
var myOptions = {
zoom: 15,
center: latlng,
mapTypeControl: false,
navigationControlOptions: { style: google.maps.NavigationControlStyle.SMALL },
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("mapcanvas"), myOptions);
var marker = new google.maps.Marker({
position: latlng,
map: map,
title: "You are here! (at least within a " + position.coords.accuracy + " meter radius)"
});
var request = {
origin: latlng,
destination: '#Model.id',
travelMode: google.maps.DirectionsTravelMode.DRIVING
};
directionsService.route(request, function (response, status) {
if (status == google.maps.DirectionsStatus.OK) {
directionsDisplay.setDirections(response);
}
});
}
function error(msg) {
var s = document.querySelector('#status');
s.innerHTML = typeof msg == 'string' ? msg : "failed";
s.className = 'fail';
// console.log(arguments);
}
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(success, error);
} else {
error('not supported');
}
you must define the map-option for directionsDisplay
