<div ng-repeat="badgesData in deptUSersData.badges | limitTo : 7 track by $index">
........content.......
</div>
If the length of deptUSersData.badges is more than 8, I want to apply a limit of 7. How can I achieve this?
My desired solution would look something like this:
<div ng-repeat="badgesData in deptUSersData.badges
ng-if="deptUSersData.badges.length > 8" ? limitTo : 7 : '' track by $index>
In the controller, you have the ability to define a variable that can be used to restrict the number of items displayed in an ng-repeat loop, as shown below:
<div ng-repeat="badgesData in deptUSersData.badges | limitTo : myLimit track by $index">
........content.......
</div>
app.controller('someController', function($scope) {
if(deptUSersData.badges.length > 8)
$scope.myLimit = 7;
}
);
If the length of deptUsersData.badges is less than or equal to 8, the variable myLimit may end up being undefined.
Referencing the limitTo documentation:
If limit is undefined, the input will be returned unchanged.
This means that if myLimit is undefined, the filter will not be applied and all elements will be displayed.
To get the desired outcome, utilize ng-show by checking the array length and limiting it to 7 using $index < 7
ng-show="{{deptUSersData.badges.length > 8? $index < 7: true}}">
Sample code - https://codepen.io/nagasai/pen/vRRQVw
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.limit = 6;
$scope.deptUSersData = {
badges :[
1,2,3,4,5,6,7,8,9
]
}
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<div>
<div ng-repeat="badgesData in deptUSersData.badges track by $index" ng-show="{{deptUSersData.badges.length > 8? $index < 7: true}}">
{{badgesData}}
</div>
</div>
</div>Note: Adjust the array length to 8 or lower for a different display
