嵌套数组中的复杂自定义排序

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/

Answer 1

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

orderBy:'sales[0].salesNumbers'
