Angularjs filter multiple checkbox on map

Question

I want to filter according to the materials in the room in the project. For example: if checked TV checkbox show the rooms on the TV. if checked tv and wifi checkbox just list rooms that are both TV and WiFi. My example shows the TV ones but when I press the wifi button the rooms with TV are still listed even though it is not WiFi.

This is: Fiddle

 angular.module('hotelApp', [])
    .controller('ContentControler', function ($scope, $timeout) {

    var mapOptions = {
        zoom: 2,
        center: new google.maps.LatLng(40.0000, -98.0000),
        mapTypeId: google.maps.MapTypeId.TERRAIN
    }
    $scope.location_name = "";
    $scope.names = [{
        prop_Name: 'Location 1',
        lat: 43.7000,
        long: -79.4000,
        amenities: '3'
    }, {
        prop_Name: 'Location 2',
        lat: 40.6700,
        long: -73.9400,
        amenities: '2'

With your current script, when you select 2 elements, like TV and WiFi, you are showing the rooms that have TV or WiFi. You should change your code in order to select only the rooms that have TV and WiFi, so your inner function $scope.ot_Filter will be as follows:

$scope.ot_Filter = function (location) {
    var shouldBeShown = true;
    for (var i = 0; i < x.length; i++) {
        if (location.amenities.indexOf(x[i]) === -1) {
            shouldBeShown = false;
            break;
        }
    }
    return shouldBeShown;
};

I've modified your script, adding WiFi to a location, here

There was a final problem when the program finished. How to avoid filtering when page loads first time. For example : Opening page with tv checked ?

You only check if something is checked and then set shouldBeShown to true and break. So you check for "OR" and not for "AND" with your checkboxes.

See your $scope.am_en = function():

for (var i = 0; i < x.length; i++) {
            if (location.amenities.indexOf(x[i]) !== -1) {
                shouldBeShown = true;
                break;
            }
}
return shouldBeShown;

You need to modify your if-statement to check ALL checked checkboxes/filters. Maybe you can think about using binary information for amenities.

Example:

00 = no amenity
01 = only WiFi
10 = only TV
11 = TV and WiFi

Then you can store:

0 for nothing
1 for only WiFi
2 for only TV
3 for TV and Wifi
...

This would make a check easier as you can use the modulo operator.
