Having issues with using the limitTo filter through javascript
The angularjs docs for limitTo state that the filter is to be used in the following way:
$filter('limitTo')(input, limit, begin)
please note the begin parameter is optional.
Following from the above I did the following:
var myApp = angular.module('myApp',[]);
function MyCtrl($scope,$filter) {
$scope.numbers =[1,2,4,1,8,11,345,123,908,223,4646,132,24,43,3,76,432,1];
$filter('limitTo')($scope.numbers, 3);
}
<div ng-controller="MyCtrl">
{{numbers}}
</div>
I expect my output to be
[1,2,4]
Yet the whole array was shown meaning the limitTo filter didn't work.
What am I doing wrong?
Angular's $filter
doesn't modify the original array, so you have to do it like this:
$scope.filteredArray = $filter('limitTo')($scope.numbers, 3);
