问题
I have a list of post with ids like
1,2,3,4,5,6,7,8,9,10,11,12
(json format)
The ids are of type String. But I would like to order it according to its numerical order
Normal orderBy:'fiche.id' the list is displayed as below.
1,10,11,12,2,3,4,5,6,7,8,9
I would like the output to be of order - 1,2,3,4,5,6,7,8,9,10,11,12

I guess your ids are strings. A simple solution would be use a no. operation inside order by. So instead ofr orderBy:'id' just use orderBy:'id*1' this will consider the id as no. and sort it according to the numerical order.
This is all you need - <div ng-repeat="fiche in fiches | orderBy:'id*1'">{{fiche.id}}</div>

Ideally it should Print the correct list in ng-repeat using order-by. I am adding a fiddle example with the same.Its a basic example. Hope it helps
