custom order function

[Jakub Arnold]

I have a ng-repeat with some things, and I want to use a custom function to sort them (basically a function that takes two items and compares them).

I tried something like

<div ng-repeat="item in items | orderBy:foo">

where foo is defined like

$scope.foo = function(a, b) {

  return -1; // tried many values here, but nothing works

}

How would I do this properly in angular?

Hi!

It should work OK, you just need to implement your function as described in http://docs.angularjs.org/api/ng.filter:orderBy :

function: Getter function. The result of this function will be sorted using the <, =, > operator.

So basically you need to return something depending on your (a,b) arguments that will be compared using standard comparison operators. If you return -1 all items are considered as equal so sort has no effect. I could help more if you could share code example with jsFiddle (or at least how your a,b looks like).

Cheers,

Pawel
