I'm building JS app.Tasks are:
1.Locate me and find nearest ATMs of specified bank
2.Then sort what she found in list.Sort by distance from me.
3.On the end are some design like a image on marker of store etc..
Well I did to locate me and to show me locations of ATMs
But I can't figure out to create list and sort that ATMs by distance from me
Does someone can help me
My code is

I am creating a webpage, in which it first get user location & then update map with user current location by showing a marker to user where he is now. But i want to get user location continuously after 500 milliseconds, But it is showing popup to user again & again to allow his location. But i want that if a user allow previous then popup will not shown to him again. Below is my for that.

EDIT
Just tested it and had the same problem than you, when just drag and dropping the html file into the browser. It seems, that the browser doesn't set the permission for a local file.
Running a local web server like serve solves the problem.
I am making a webpage with Google Maps API but I am getting "google not defined error"
How can I get rid of this?
How can I import Google or do something to make this piece of code work?
I want a program in which user will enter location and it shows marker there. but it is not working properly.
Here is my code:

initMap function should be closed at last you are closing it before
var searchBox = new google.maps.places.SearchBox(document.getElementById('mapsearch'));
So you are getting google undefined error.
Also you have add parameter &libraries=places to google map script src
working example

Most likely your google APIs have not loaded, when your script needs them - hence the "google not defined error". Move this before your script and drop the async defer - or do your script inside a "$( document ).ready"

I'm trying to get markers for restaurants to drop on my map and it's not working. Any help would be appreciated. Do I need to add a query method? I am trying not too as I'm going to let the location be static when finished. Here is my relevant code,
<script>
var map;
function initialize() {
var center = new google.maps.LatLng(37.422, -122.084058);
map = new google.maps.Map(document.getElementById('map'), {
center: center,
zoom: 13
});
var request = {
location: center,
radius: 8047,
types: ['restaurant']
};
var service = new google.places.PlaceService(map);
service.nearbySearch(request, callback);
}
function callback(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
for (var i = 0; i < results.length; i++) {
createMarker(results[i]);
}
}
}
function createMarker(place) {
var placeLoc = place.geometry.location;
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location
});
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
PlacesService needs an API_KEY.
var map;
var infowindow;
function initMap() {
var center = new google.maps.LatLng(37.422, -122.084058);
map = new google.maps.Map(document.getElementById('map'), {

Just as the title states. I have tried google.maps.places.RankBy.PROMINENCE (default) and setting the radius to 50000 and am returned 20 results. But when I try the exact same search, minus the radius as according to the documentation, and using google.maps.places.RankBy.DISTANCE I am only returned 3 results in a short radius of my locations. Can someone explain why this happens and how to get a nearby search by distance with full results. Maybe I am just doing something wrong. Thanks.
The code bellow returns 20 results using google.maps.places.RankBy.PROMINENCE
var map;
var infowindow;
function initMap() {
var location = {lat: 43.139387, lng: -80.264425};
map = new google.maps.Map(document.getElementById('map'), {
center: location,
zoom: 9
});
infowindow = new google.maps.InfoWindow();
var service = new google.maps.places.PlacesService(map);
service.nearbySearch({
location: location,
radius: 50000,
types: ['police'],
// rankBy: google.maps.places.RankBy.DISTANCE
}, callback);
}
function callback(results, status) {
if (status === google.maps.places.PlacesServiceStatus.OK) {
for (var i = 0; i < results.length; i++) {
createMarker(results[i]);
}
}
}
function createMarker(place) {
var placeLoc = place.geometry.location;
var marker = new google.maps.Marker({
map: map,
position: place.geometry.location
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(place.name);
infowindow.open(map, this);
});

The radius attribute for the PROMINENCE code may have an effect on the search result. And based on the Places documentation, it can be affected by Google's index, global popularity, etc.
For DISTANCE, the optional attributes such as keyword, name, and types are now required.
Hope this clarifies some points regarding your issue.
I am trying to write a program in javascript related to finding my place by using google maps APIs and the browser navigator and then put a marker on the place.My code works properly for this part. But for the second part that I want to find the nearby places and put markers on them does not work and I cannot find the problem. It gives me an error about the map variable. It seems the code breaks and cannot get the map variable for performsearch function. Any idea would be highly appreciated?

There are several issues. Fixed code(modifications are commented inside):
var map;
function handleSearchResults(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
for (var i = 0; i < results.length; i++) {
var marker = new google.maps.Marker({
//typo: it must be location not Location
position: results[i].geometry.location,
map: map,
icon: results[i].icon
});
}
}
}
function performSearch() {
var request = {
bounds: map.getBounds(),
name: "McDonald's"
};
var service = new google.maps.places.PlacesService(map);
//use only the name of the function as callback-argument
service.nearbySearch(request, handleSearchResults);
}
function initialize(location) {
var myLatlng = new google.maps.LatLng(location.coords.latitude,
location.coords.longitude);
var mapOptions = {
center: myLatlng,
zoom: 9
};
//removed the var-keyword(otherwise map is not global accessible)
map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: "My place"
});
//again: use only the name of the function as callback-argument
service = new google.maps.event.addListenerOnce(map,
'bounds_changed',
performSearch);
}
$(document).ready(function () {
navigator.geolocation.getCurrentPosition(initialize);
});
But note: geolocating may fail, currently the map will never be initialized when it fails. You better separate the map-creation from the geolocating
