getCurrentPosition on chrome breaks javascript - javascript

I have a page where I am loading google maps. I use getCurrentPosition over http and even I receive a warning from google api. The problem is that it breaks also the javascript and that ruins everything. The code was working for quite some time but the last week things broke.
Below is the html and script. You can add it in html and run it and see (tried with stackoverflow but had some issues with the script)

getCurrentLocation is only supported over https:// now on Chrome.
There has been a warning in place in the javascript console in Chrome for quite a while, and it was announced a while ago.
reference from your comment
Starting with Chrome 50, Chrome no longer supports obtaining the user’s location using the HTML5 Geolocation API from pages delivered by non-secure connections. This means that the page that’s making the Geolocation API call must be served from a secure context such as HTTPS.

Google Maps Marker doesn't show up in my website

Can someone help me please I don't understand javascript
<script type="text/javascript">
var myOptions = {
zoom: 16,
center: new google.maps.LatLng(31.6321288,-8.0099319,787),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var myLatLng = new google.maps.LatLng(31.6321288,-8.0099319,787);
var beachMarker = new google.maps.Marker({
position: myLatLng,
map: map,
icon: "We Are Here"
});
</script>
According to the Google Documentation, it is as follows.
Make sure you include this line in your html tag and get your Google Map API Key to replace the YOUR_API_KEY
<script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<title>Simple markers</title>
<style>
html, body {
height: 100%;
margin: 0;
padding: 0;
}
#map {
height: 100%;
}
</style>
</head>
<body>
<div id="map"></div>
<script>
function initMap() {
var myLatLng = {lat: -25.363, lng: 131.044};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: myLatLng
});
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: 'Hello World!'
});
}
</script>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
</script>
</body>
</html>
1 - You need to create a Google Maps project and generate an API KEY (https://console.developers.google.com). It's very simple and fast.
2 - So, you need to import GoogleMapsAPI, changing YOUR_API_KEY for your API KEY:
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
</script>
The result is something like this:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
<title>Simple markers</title>
<style>
html, body {
height: 100%;
margin: 0;
padding: 0;
}
#map {
height: 100%;
}
</style>
</head>
<body>
<div id="map"></div>
<script>
function initMap() {
var myLatLng = {lat:31.6321288, lng:-8.0099319};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 16,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: 'Hello World!'
});
}
</script>

I can see it works here, but it doesn't.
Thanks for the help.

Dynamic google map creation using same division and variable

I am trying to generate map onclick on same division and same variable "map" using following script, it's not functioning, I don't know how to destroy old map and recreate please someone help me.. this is what I have tried so far..
Here is link to fiddle
JS
function map(lat,lon){
jQuery(document).ready(function () {
var centerPosition = new google.maps.LatLng(lat, lon);
var options = {
zoom: 16,
center: centerPosition,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), options);
});
}
var lat =22, lon = 75;
map(lat,lon);
HTML
<div id="map"></div>
<button onclick="map(15,90)" >15 90</button>
<button onclick="map(22,80)" >22 80</button>
CSS
#map {
height: 300px;
width: 500px;
}
button{ width:70px;height:40px;}
function map(lat,lon){
// jQuery(document).ready(function () {
var centerPosition = new google.maps.LatLng(lat, lon);
var options = {
zoom: 16,
center: centerPosition,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), options);
//});
}
i didn't make test for it, just look through to check the syntax

How to make the little guy in google map snap back to the nearest point if threw away?

In this google map sample: http://code.google.com/apis/maps/documentation/javascript/examples/streetview-simple.html
If the user dropped the little guy far away in the middle of the ocean for example, it disappears.
But in the main google map website http://maps.google.com/ If you made it show the street view, and the user dragged the guy away it get back automatically to the previous point.
What is missed in the first example to make it behave the same as the google map website?
here is the code of the sample:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8"/>
<title>Google Maps JavaScript API Example: Street View Layer</title>
<link href="http://code.google.com/apis/maps/documentation/javascript/examples/standard.css" rel="stylesheet" type="text/css" />
<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"></script>
<script type="text/javascript">
function initialize() {
var fenway = new google.maps.LatLng(42.345573,-71.098326);
var mapOptions = {
center: fenway,
zoom: 14,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(
document.getElementById("map_canvas"), mapOptions);
var panoramaOptions = {
position: fenway,
pov: {
heading: 34,
pitch: 10,
zoom: 1
}
};
var panorama = new google.maps.StreetViewPanorama(document.getElementById("pano"),panoramaOptions);
map.setStreetView(panorama);
}
</script>
</head>
<body onload="initialize()">
<div id="map_canvas" style="width: 400px; height: 300px"></div>
<div id="pano" style="position:absolute; left:410px; top: 8px; width: 400px; height: 300px;"></div>
</body>
</html>
To do this, add an event listener to position_changed and use it to store the last (valid) location that pegman was dropped.
google.maps.event.addListener(panorama, 'position_changed', function() {
// Store position
});
And then add an event listener to visibility_changed (which is triggered when pegman is dropped in the ocean) to set him back to the last known location:
google.maps.event.addListener(panorama, 'visible_changed', function() {
if (panorama.getVisible() == false && last_location) {
panorama.setPosition(last_location);
}
});
