Using Angular ng-repeat to iterate over a mysteriously empty Array

To display a certain element multiple times in a row, I am looking for a way that does not involve using the do(x times) function in Angular or adding extra functions in the controller.

If we consider

?Array.from({length:5})
(5) [undefined, undefined, undefined, undefined, undefined]

Is there a way to modify the following code to achieve the desired result without relying on additional functions or filters in the controller (and without using a controller at all)?

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js">
</script>

<div ng-app>
  [1,2] - OK:
  <div ng-repeat="x in [1,2]">
    > {{x}}
  </div>

  Array.from({length:5}) - NOK:
  <div ng-repeat="x in Array.from({length:5})">
    > {{x}}
  </div>
</div>

PS

I need 5 ">" symbols displayed instead of numbers.

PPS.

Practical scenario:
I need to show the last page of a paginated table based on "availableRowsNumber" and "itemsPerPage". To ensure a consistent height, empty rows must be added:

<div ng-repeat="x in Array.from({length:itemsPerPage-itemsPerPage%availableRowsNumber})">
    <tr></tr>
</div>

Answer №1

One way to achieve this is by utilizing .constructor

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js">
</script>

<div ng-app>
  <div ng-repeat="x in [].constructor(5) track by $index">
     <span>something of your choice to be displayed</span>
  </div>
</div>

Answer №2

One way to filter items in Angular is by using ng-if as demonstrated by Mike:

<div ng-repeat="item in items track by $index" ng-if="$index < 5">
</div>

Another option is to utilize the limitTo filter:

<div ng-repeat="item in items | limitTo: 5 track by $index">
</div>
