Error: 10 $digest() iterations reached. Aborting! with dynamic sortby predicate

I have the following code which repeats and displays name of the user and his score:

<div ng-controller="AngularCtrl" ng-app>
<div ng-repeat="user in users | orderBy:predicate:reverse | limitTo:10">
<div ng-init="">
{{}} and {{user.score}}

And the corresponding angular controller.

function AngularCtrl($scope) {
$scope.predicate = 'score';
$scope.reverse = true;
$scope.users = [{id: 1, name: 'John'}, {id: 2, name: 'Ken'}, {id: 3, name: 'smith'}, {id: 4, name: 'kevin'}, {id: 5, name: 'bob'}, {id: 6, name: 'Dev'}, {id: 7, name: 'Joe'}, {id: 8, name: 'kevin'}, {id: 9, name: 'John'}, {id: 10, name: 'Ken'}, {id: 11, name: 'John'}, {id: 1, name: 'John'}, {id: 2, name: 'Ken'}, {id: 3, name: 'smith'}, {id: 4, name: 'kevin'}, {id: 5, name: 'bob'}, {id: 6, name: 'Dev'}, {id: 7, name: 'Joe'}, {id: 8, name: 'kevin'}, {id: 9, name: 'John'}, {id: 10, name: 'Ken'}]

When I run the above code, I get the Error: 10 $digest() iterations reached. Aborting! error in my console.

I have created jsfiddle for same.

The sort predicate is being initalized only inside the ng-repeat and also the limit is being applied on the number of objects. so I feel having both the sortby and limitTo watchers together is the reason for error.

If the $scope.reverse is false (ascending order of score), then it does not error.

Can anyone help me understand what is wrong here? Much appreciate your help.


Please check this jsFiddle: (The code is basically the same you posted but I use an element instead of the window to bind the scroll events).

As far as I can see, there is no problem with the code you posted. The error you mentioned normally occurs when you create a loop of changes over a property. For example, like when you watch for changes on a certain property and then change the value of that property on the listener:

$scope.$watch('users', function(value) {
  $scope.users = [];

This will result on an error message:

Uncaught Error: 10 $digest() iterations reached. Aborting!
Watchers fired in the last 5 iterations: ...

Make sure that your code doesn't have this kind of situations.


This is your problem:

<div ng-init=""> 

You shouldn't change objects/models during the render or otherwise it will force a new render (and consequently a loop, which causes the 'Error: 10 $digest() iterations reached. Aborting!').

If you want to update the model, do it on the Controller or on a Directive, never on the view. angularjs documentation recommends not to use the ng-init exactly to avoid these kind of situations:

Use ngInit directive in templates (for toy/example apps only, not recommended for real applications)

Here's a jsFiddle with an working example:
