});
}
}({}));
Notice options: editable: true and draggable: true. With these options circles are editable and draggable.
Also notice line: var p = Math.pow(2, (21 - map.getZoom())); and option radius: p * 1128.497220 * 0.0027. Like this circle is always proportional to zoom level. Live example:

(function (ns) {
/*globals google, map*/
"use strict";
var map;
function initMap() {
try {
map = new google.maps.Map(document.getElementById('map-canvas'), {
center: { lat: 34.397, lng: 150.644 },
scrollwheel: true,
zoom: 2
});
}
catch (e) {
console.log(e);
setTimeout(function () {
if (typeof google !== 'object') {
location.reload();
}
}, 1000);
}
ns.map = map;
}
ns.initMap = initMap;
})(window.milosev);
POI fix for "google is not defined" error:
setTimeout(function () {
if (typeof google !== 'object') {
location.reload();
}
}, 1000);
POI fix for "initMap is not a function" error:
function initMap() {
map = new google.maps.Map(document.getElementById('map-canvas'), {
center: { lat: 34.397, lng: 150.644 },
scrollwheel: false,
zoom: 2
});
ns.map = map;
}
Where HTML part should look like:
<script defer type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=myKey;callback=window.milosev.initMap"></script>Notice: window.milosev.initMap My solution for zoom after fitBounds:
(function (ns) {
/*globals google, $*/
"use strict";
$.getJSON("djala.json", function (data) {
data.forEach(function (file) {
var picsLatLng = new google.maps.LatLng(file.Latitude, file.Longitude);
var bounds = new google.maps.LatLngBounds();
var marker = new google.maps.Marker({
position: picsLatLng,
map: ns.map,
title: file.FileName,
url: file.FileName
});
marker.addListener('click', function () {
window.open(marker.url, "_target");
});
bounds.extend(picsLatLng);
ns.map.fitBounds(bounds);
var zoomChangeBoundsListener =
google.maps.event.addListenerOnce(ns.map, 'bounds_changed', function(event) {
if ( ns.map.getZoom() ){
ns.map.setZoom(14); // set zoom here
}
});
setTimeout(function(){
google.maps.event.removeListener(zoomChangeBoundsListener);
}, 2000);
});
});
})(window.milosev);
POI:
var zoomChangeBoundsListener =
google.maps.event.addListenerOnce(ns.map, 'bounds_changed', function(event) {
if ( ns.map.getZoom() ){
ns.map.setZoom(14); // set zoom here
}
});
setTimeout(function(){
google.maps.event.removeListener(zoomChangeBoundsListener);
}, 2000);

Title I have stolen from here.
Here is my example. This example will return five times five:
for (var i=0; i < 5; i++) {
setTimeout(function () {
console.log(i)
}, i*1000)
}
And this example will return 0, 1, 2, 3, 4:
var aa = function (a) {setTimeout(function () {
console.log(a)
}, i*1000)};
for (var i=0; i < 5; i++) {
aa(i);
}

One example of swiping with old version of swiper.
HTML:
<div class="swiper-container"> <div class="swiper-wrapper"> <div class="swiper-slide"> Test slide one </div> <div class="swiper-slide"> Test slide two </div> <div class="swiper-slide"> Test slide three </div> </div> </div>
JS:
$('.swiper-container').swiper({
grabCursor: true
});
Live example you can see here.
