maps markers with input sliders

Question

Let me explain the project a bit. i have a huge list of stores with addresses (longitude and latitude and code client ....).

Now, my problem is, i must be able to filter

Answer 1

The implementation is similar to the answer I mentioned before. You should add an input for code of client and a search button. In the function where you create markers add a property 'code' for each marker marker.code = CodeClient;. When you click search button it executes the filterByCode() function. If you pass empty value it restores all markers.

Have a look at modified code

// necessary variables
var map;
var infoWindow;
var markersData = [];
var markerCluster;
var markerArray = []; //create a global array to store markers

function initialize() {
  var mapOptions = {
    center: new google.maps.LatLng(32, -6),
    zoom: 7,
    mapTypeId: 'roadmap',
  };
  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

  // create MarkerClusterer, markersArray is not populated yet
  markerCluster = new MarkerClusterer(map, [], {
    imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'
  });

  // a new Info Window is created
  infoWindow = new google.maps.InfoWindow();

  // Event that closes the Info Window with a click on the map
  google.maps.event.addListener(map, 'click', function() {
    infoWindow.close();
  });
  // Finally displayMarkers() function is called to begin the markers creation
  displayMarkers();
}
google.maps.event.addDomListener(window, 'load', initialize);


// This function will iterate over markersData array
// creating markers with createMarker function
function displayMarkers() {

  // this variable sets the map bounds according to markers position
  var bounds = new google.maps.LatLngBounds();

  // for loop traverses markersData array calling createMarker function for each marker 
  $.get("https://gist.githubusercontent.com/abdelhakimsalama/358669eda44d8d221bf58c629402c40b/raw/bae93c852669a35f0e7053e9f8d068841ddf146a/get_data_google_api", function(response) {
