Rearranging Arrays in AngularJS: Ensuring a Specific Element Stays at the

I have exhaustively searched for an answer to my query without success. I hope that my search efforts were sufficient! Here is the issue at hand :

<div id="{{expression.comment_id.$id}}" class="comments" ng-repeat="expression in expressions| orderBy:orderProp"

The 'orderBy' functionality is functioning well, however, I need a specific customization: I want the expressions with comment_id '0' to always appear at the top.

How can I achieve this? I believe using a custom filter may be the most effective solution, but I am unsure of the correct implementation. If this approach is appropriate, can you guide me on how to do it correctly?

Thank you for your assistance!

Answer №1

To assist you, I have created a fiddle: http://jsfiddle.net/sameersemna/81q9jwg9/

Your task involves implementing a custom orderBy filter:

<ul ng-repeat="expression in expressions | orderBy:myValueFunction">

In the controller:

$scope.myValueFunction = function(expression) {
        if(expression.comment_id == 0){
            return expression.comment_id;
        }else{
            return expression.orderProp;
        }
    }
