AngularJS restricts the display of elements to only 4 using the limitTo filter

I'm facing an issue with my filters. I have a JSON dataset that I need to display on my website, but I only want to show 4 elements that meet a certain criteria. Here's the code snippet:

<div ng-repeat="place in places | limitTo: 4 | filter: {cheap: 'true'}" class="col-lg-3">

My problem is that if the first element in the JSON data has "cheap = false," only 3 items are displayed instead of 4. It seems like the ng-repeat starts counting from the beginning of the dataset and stops at the 4th element, regardless of whether it meets the filter condition.

Is there a way to modify the filter to skip over any elements that don't meet the criteria, so that I can display the next 4 true elements?

I hope this explanation makes sense. Thank you for your assistance!

Answer №1

To achieve the desired outcome, make sure to place the limitTo directive after the filter directive.

var myApp = angular.module('myApp', []);


function MyCtrl($scope) {
  $scope.places = [{
    cheap: true
  }, {
    cheap: true
  }, {
    cheap: false
  }, {
    cheap: true
  }, {
    cheap: true
  }, {
    cheap: true
  }, {
    cheap: true
  }, ]
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp">
  <div ng-controller="MyCtrl">
    <h1>Good</h1>
    <div ng-repeat="place in places  | filter: {cheap: 'true'} | limitTo: 4" class="col-lg-3">
      {{place.cheap}}
    </div>

    <h1>Bad</h1>
    <div ng-repeat="place in places| limitTo: 4  | filter: {cheap: 'true'} " class="col-lg-3">
      {{place.cheap}}
    </div>
  </div>
</div>

After reading the advice in the comments, I realized a simple solution - all I had to do was rearrange the order and place "filter:" before "limitTo:". Thanks for the help!
