complicated custom sorting in nested array

Question

I've problem sorting my nested array, says I've json like this

var orders = [{
    'orderId': 1,
        'sales': [{
        'salesNumbers': 3
    }]
}, {
    'orderId': 2,
        'sales': [{
        'salesNumbers': 4

    }]
}];

and I wish I can sort orderId base on salesNumbers. You may say it's impossible or I made a mistake by putting sales as array but it contain only 1 object which is salesNumbers. That's not a mistake, I just do not want to simplify my problem.

so it's possible to, without changing the data structure, sort orderId base on salesNumbers?? My app demo http://jsfiddle.net/sq2C3/

Yes, it's possible. it's just like sorting any other Array of Objects. You just need to target the nested object/field to sort on. — cookie monster

Since you say the sales array only has one item in it, you can order by salesNumbers like this:

orderBy:'sales[0].salesNumbers'

Here is an update of your fiddle: http://jsfiddle.net/wittwerj/sq2C3/2/

just curious hw angular know which sales I refer to? I mean I can have sales in somewhere of my json too

orderBy can only see properties on the order object created by ng-repeat.

thanks. I found my problem still haven't solve, what if I've multiple item in my sales array? I can't do loop in <li>

you mean you want to sort the orders by their max salesNumbers, not the first one? for that i believe you will need a custom filter, or presort your data in the controller. see stackoverflow.com/questions/14493116/…
