Troubleshooting ng-repeat in AngularJS: Multi checkbox filter malfunction

My AngularJS app has multiple age range filters implemented, but one of them is not functioning correctly and I can't figure out why.

You can view a functional example here.

The various filters are defined as follows:

.filter('five', function () {
  return function ( items, filter) {
      if(filter) return items.filter(x => x.age <= 4);
      else return items;
  }
})

.filter('child', function () {
  return function ( items, filter) {
      if(filter) return (items.filter(x => x.age >= 5) && items.filter(x => x.age <= 14));
      else return items;
  }
})

.filter('young', function () {
  return function ( items, filter) {
      if(filter) return (items.filter(x => x.age >= 14) && items.filter(x => x.age <= 17));
      else return items;
  }
})

.filter('adult', function () {
  return function ( items, filter) {
      if(filter) return items.filter(x => x.age >= 18);
      else return items;
  }
})

In the view, the filters are applied like this:

<div ng-repeat="item in data 
    | five:fiveFilter 
    | adult:adultFilter 
    | young:youngFilter 
    | child:childFilter">
 {{item.age}}
</div>

While all filters are working properly, the young filter seems to be malfunctioning. Any ideas on what might be causing this issue?

Answer №1

Revise this filter code:

.filter('childFilter', function () {
  return function (items, ageFilter) {
      if (ageFilter) return items.filter(x => x.age >= 5 && x.age <= 14);
      else return items;
  }
})


.filter('youthFilter', function () {
  return function (items, ageFilter) {
      if (ageFilter) return items.filter(x => x.age >= 14 && x.age <= 17);
      else return items;
  }
})
