Google Maps API loads from html file, but not on local host - javascript

I am trying to connect to the Google Maps API from a localhost through an AngularJS application but the map does not appear and the map request does not reach google. The javascript file is being found by the html, and test1 is being outputted in the console, but initMap is not being called and test2 is not outputted. I expect that it is failing because a https connection is not being made to Google.
When I open the html file in a browser, the map loads fine but when I run it on my localhost, nothing comes up.
Here is my html code:
<script src="client/services/maps.client.services.map.js"></script>
<script src="https://maps.googleapis.com/maps/api/js?key={{API_KEY}}&callback=initMap"></script>
and javascript (map.js):
console.log('test1');
function initMap() {
console.log('test2');
//Markers
var markers = [
['Cardiff', 51.4539, -3.1694, 'city/cardiff'],
['Swansea', 51.6148, -3.92927895, 'city/swansea']
];
// Initialise map
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: {lat: 51.4539, lng: -3.1694}
});
var bounds = new google.maps.LatLngBounds();
for( i = 0; i < markers.length; i++ ) {
// Plot pin for each place
var position = new google.maps.LatLng(markers[i][1], markers[i][2]);
bounds.extend(position);
marker = new google.maps.Marker({
position: position,
map: map,
title: markers[i][0]
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
window.location.href = markers[i][3];
}
})(marker, i));
}
// Zoom so all pins are in view
map.fitBounds(bounds);
}
Does anyone understand why the initMap function is not being called?

change the order of the script tags
<script src="https://maps.googleapis.com/maps/api/js?key={{API_KEY}}&callback=initMap"></script>
<script src="client/services/maps.client.services.map.js"></script>

Multiple markers working on my local server but markers not working on my live site. http://www.sierracrestweb.com/dev/

Here is the code below, Perfectly display the purple icon on my local server but markers not shown on my website, I search on google and try alternate method but still facing this problem, I guess it is due to Multiple loading API Key errors, but if this How to resolve this error? because I already remove all the script but still face the problem.

</script>
If the marker creation is working on your local but not on server then it is probably not related to the code itself.
I think that the issue is with this line.
var locations = <?php get_all_locations() ?>;
Most likely this function is returning a blank array due to which no markers are plotted on the map.
Try printing out the value of the returned array in the console to ensure that you are indeed getting the correct location array.
var locations = <?php get_all_locations() ?>;
console.log(locations);

Google maps api with infowindow not working

I'm trying to create a map with info windows that open with the user clicks on a marker. So far the code doesn't seem to be working, the map was displaying before but once I put in the code for the info window pop-ups not only did the info window not show but the map also stopped showing on my webpage. Here's the code:
<div id= "map"> </div>
<script>
var map;
var markers=[];
function initMap(){
map= new google.maps.Map(document.getElementById('map'),{
center:{ lat:40.7413549, lng:-73.9980244},
zoom:13
});
var locations=[
{title:"Park Ave Penthouse",location:{lat:40.7713024,lng:-73.9632393}},
{title:"Chelsea Loft", location;{lat:40.7444883,lng:-73.9949465}},
{title:"Union Square Open Floor Plan",location:{lat:40.7347062,lng:-73.984377}},
{title:"East Village Hip Studio",location:{lat:40.7281777,lng:-73.984377}},
{title:"TriBeCa Artsy Bachelor Pad",location:{lat:40.7195264,lng:-74.0089934}},
{title:"Chinatown Homey Space",location:{lat:40.7180628,lng:-73.9961237}}
];
var largeInfowindow= new google.maps.InfoWindow();
var bounds= new google.maps.LatLngBounds();
for (var i=0; i< locations.lenght;i++){
var position = locations[i].location;
var title = locations[i].title;
var marker= new google.maps.Marker({
map: map,
position:position,
title:title,
animation:google.maps.Animation.Drop,
id:i
});
markers.push(marker);
bounds.extend(marker.position);
marker.addListner ("click",function(){
populateInfoWindow(this,largeInfowindow);
});
map.fitBounds(bounds);
};
markers.push(marker);
markers.addListner("click",function(){
populateInfoWindow(this,largeInfoWindow);
});
}
function populateInfoWindow (marker, infowindow){
if(infowindow.marker=!marker){
infowindow.marker= marker;
infowindow.setContent("<div>"+marker.title+"</div>");
infowindow.open(map,marker);
infowindow.addListner("closeclick",function(){
infowindow.setMarker(null);
});
}
}
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyAvrWT4KKcsDSSGYXpxRry3m7j90pPjZgA&v=3&callback=initMap"></script>
The error is in this line:
if(infowindow.marker=!marker){ //it is "!=" and not "=!"
Always check console for javascript errors. After infowindow code, you could not even see the mao which means you have javascript errors.

Google maps API recenter my map

My code for the initialization of the API looks like so:
jQuery(function($) {
// Asynchronously Load the map API
var script = document.createElement('script');
script.src = "http://maps.googleapis.com/maps/api/js?sensor=false&callback=initialize";
document.body.appendChild(script);
});
function initialize() {
var bounds = new google.maps.LatLngBounds();
var mapOptions = {
mapTypeId: 'roadmap'
};
// Display a map on the page
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
map.setTilt(45);
// Multiple Markers
var markers = [
//php code to get markers from DB
];
// Info Window Content
var infoWindowContent = ['some text here'];
// Display multiple markers on a map
var infoWindow = new google.maps.InfoWindow(), marker, i;
// Loop through our array of markers & place each one on the map
for( i = 0; i < markers.length; i++ ) {
var position = new google.maps.LatLng(markers[i][1], markers[i][2]);
bounds.extend(position);
marker = new google.maps.Marker({
position: position,
map: map,
title: markers[i][0]
});
//push markers to mapMarkers array.
mapMarkers.push(marker);
// Allow each marker to have an info window
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infoWindow.setContent(infoWindowContent[i][0]);
infoWindow.open(map, marker);
}
})(marker, i));
// Automatically center the map fitting all markers on the screen
map.fitBounds(bounds);
}
}
Problem is I dont want the map to be centered around my markers I get from the database anymore. But if I delete map.fitBounds(bounds); and try to use map.setCenter({lat: -34, lng: 151}); I get a blank screen. If I even touch anything in this code I get a blank screen instead of my map!
A map must have a zoom.
You didn't initially set a zoom for the map.
When you use fitBounds() the zoom will be set automatically, but when you didn't use it the zoom is still missing.
Solution: set a zoom in mapOptions

Markers won't show on google maps

I need to place multiple markers on a google map. Here's the problem: I have an array of latitude/longitude data. I need to make a marker appear on the map for each lat/lng pair. But it won't. If I ask the function to print out the coordinates instead of marking them on the, map, it works fine. I don't get an error message either way, so I'm stuck. The page displays the map but without any markers. Here's the code of the function that should add markers:
//adds markers to the map
function addMarkers(locarray) {
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locarray.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locarray[i][0], locarray[i][1]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent('some words');
infowindow.open(map, marker);
}
})(marker, i));
}
}
Here's the initialize function (called on body load):
function initialize() {
geocoder = new google.maps.Geocoder();
var latlng = codeAddress("<?php echo $_POST['postal']; ?>");
var myOptions = {
zoom: 11,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
geocoder and map are declared as global variables. The codeAddress function returns lat and lng of the place I want to center the map around, it's been tested and works perfectly. It is NOT the problem, I'm leaving it out to simplify and keep PHP out of this.
And here is the script that declares the array and calls the addMarkers function:
<script type='text/javascript'>
var locations = [
[-33.890542, 151.274856],
[-33.923036, 151.259052],
[-34.028249, 151.157507]
];
addMarkers(locations)
</script>
Does anyone see anything wrong with this?

Automatically opening marker info pane on google map

I've created a custom map with most things I want on it (custom icon and custom info bubble), however I can't find a solution to automatically open the markers info window on load, I've done alot of searching but can't seem to find anything the code I have so far is as follows, any help would be much appreciated:
function initialize() {
var myLatlng = new google.maps.LatLng(54.325109,-2.742226);
var myOptions = {
zoom: 15,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var countries = [
{
title:'Remedy',
lat:54.3210,
lon:-2.7438,
content:"<h2>Remedy</h2><p>address, <br />location, <br />postcode</p> <p><b>T:</b> 07595 153 835 <br /><b>E:</b> <a href='mailto:email'>email</a></p>"
}
];
for (var i = 0; i < countries.length; i++) {
var c = countries[i];
c.marker = new google.maps.Marker({
position: new google.maps.LatLng(c.lat, c.lon),
map: map,
icon: '/wp-content/themes/remedy/display_images/google_map_icon.png',
title: c.title});
c.infowindow = new google.maps.InfoWindow({content: c.content});
google.maps.event.addListener(c.marker, 'click', makeCallback(c));
}
function makeCallback(country) {
return function () {
country.infowindow.open(map, country.marker);
};
}
infowindow.open(map, marker);
}
Maybe it's not working because you just created the instance of the Map and didn't wait for the complete load of the map to open the InfoWindow.
Try something like this:
google.maps.event.addListenerOnce(map, 'tilesloaded', function(event) {
infowindow.open(map, marker);
});
According to the reference:
http://code.google.com/intl/en/apis/maps/documentation/javascript/reference.html#Map
tilesloaded - This event is fired when the visible tiles have finished loading.
Hmm, inforwindow does not refer to anything in your code, which is why it is not working.
Since you have one country in the list as of now you can do a quick test and intialize the infowindow variable with an actual info window, or better yet also since you have 1 item in the list, just define c to be outside the loop so you can access it and then open the popup passing it the map and the marker, something like this (assuming c has been defined outside the loop)
c.infowindow.open(map, c.marker);
var infowindow = new google.maps.InfoWindow({
content: "Test Route",
position: new google.maps.LatLng(38.8709866, -77.208055),
});
infowindow.open(map);
