I'm new to Google maps and I have problem on how should i start to get the marker around the given radius of the Address that is Centered on the Initialize()
{
<script type="text/javascript">
var geocoder, infoBubble, geocode;
var map;
var marker;
//var mgr;
function initialize() {
var minZoomLevel = 4;
var zooms = 7;
geocoder = new google.maps.Geocoder();
geocode = new google.maps.Geocoder();
// Used to Set the Center of the Maps on the Logged User
$.getJSON('/Dashboard/LoadAddress', function Geocoding(address) {
$.each(address, function () {
var currValAddress = this["AddressLine1"];
var Latitude = this["Latitude"];
var Longitude = this["Longitude"];
var LatLang = new google.maps.LatLng(Latitude, Longitude);
var addresse = {
zoom: 8,
center: LatLang,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map'), addresse);
// Bounds for North America
var strictBounds = new google.maps.LatLngBounds(
new google.maps.LatLng(15.70, -160.50),
new google.maps.LatLng(68.85, -55.90));
// Listen for the dragend event
google.maps.event.addListener(map, 'dragend', function () {
if (strictBounds.contains(map.getCenter())) return;
// We're out of bounds - Move the map back within the bounds
var c = map.getCenter(),
x = c.lng(),
y = c.lat(),
maxX = strictBounds.getNorthEast().lng(),
maxY = strictBounds.getNorthEast().lat(),
minX = strictBounds.getSouthWest().lng(),
minY = strictBounds.getSouthWest().lat();
if (x < minX) x = minX;
if (x > maxX) x = maxX;
if (y < minY) y = minY;
if (y > maxY) y = maxY;
map.setCenter(new google.maps.LatLng(y, x));
});
// Limit the zoom level
google.maps.event.addListener(map, 'zoom_changed', function () {
if (map.getZoom() < minZoomLevel) map.setZoom(minZoomLevel);
});
});
});
}
var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
function codeAddress() {
infoBubble = new InfoBubble({
map: map,
shadowStyle: 0,
padding: 10,
borderRadius: 10,
arrowSize: 15,

borderColor: '#ccc',

$.getJSON('/Dashboard/LoadWorkerList', function Geocode(addresses) {
$.each(addresses, function () {
var currVal = this["AddressLine1"];
var Name = this["Name"];
var Gender = this["Gender"];
var Bdate = this["Birthdate"];
var ID = this["Worker_ID"];
var Latitude = this["Latitude"];
var Longitude = this["Longitude"];
var LatLang = new google.maps.LatLng(Latitude, Longitude);
marker = new google.maps.Marker({
map: map,

})
var link = $('<a href="#">' + currVal + '</a>')
.data('location', LatLang);
$('#places').each(function () {
$('#places').append($('<li id=\'List\' class=\'List\'>').append(link));
});
link.on('click', function (event) {
event.preventDefault();
google.maps.event.trigger(addresses[0], "click");
infoBubble.removeTab(0);
infoBubble.addTab(Name, "Name: " + Name + "<br> Address: " + currVal + "<br> Gender: " + Gender + "<br> Birthdate: " + Bdate + "<br><br>" + '<center><a href="/Worker/WorkerDetails?workerId=' + ID + '">View Profile</a></center>');

});
google.maps.event.addListener(map, 'idle', function () {

var inside = (map.getBounds().contains($(this).find('a').data('location'))) ? '' : 'none';
$(this).css('display', inside);
});
});
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infoBubble.removeTab(0);
infoBubble.addTab(Name, "Name: " + Name + "<br> Address: " + currVal + "<br> Gender: " + Gender + "<br> Birthdate: " + Bdate + "<br><br>" + '<center><a href="/Worker/WorkerDetails?workerId=' + ID + '">View Profile</a></center>');

}
})(marker, currVal));
addresses.push(marker);
})
google.maps.event.trigger(map, 'bounds_changed');
google.maps.event.addListener(map, 'click', find_closest_marker);
})
}
window.onload = function () {
initialize();
codeAddress();
}
</script>
}
Now my question is if i add a Dropdown of Radius in miles. . how can i get distance between the initial point to the markers around it. . .and only load on the markers inside its radius like this site here
