Custom OrderBy in jLinq

Question

Is it possible in jLinq to sort my data according to a defined function?

I would like to have something like:

var res = jLinq.from(data).orderBy(function (r) { return r.x + r.y; }).select();

Currently I have implemented this solution

var index = function (r) { return r.x + r.y; };

var res = jLinq.from(data).select();
res.sort(function(a,b){ return index(a)<=index(b) ? 1 : -1; });

but I was wondering if it is feasible in jLinq before the select

You could add a computed column to your query and sort by that. Take a look at this post: Get sum of two columns in one LINQ query

In order to apply your solution it is necessery to map my object into "obj + index". I don't know if it is possible to do it in jLinq and however this sounds like a workaround.. does it means that there is no way to do it in a more direct (and elegant) way? – Roberto Jun 14 '13 at 08:32
