javascript - 按优先于其中一个的两个值排序

Question

如何按 count 和 year 值按升序对数据进行排序，并优先考虑 count 值？

//sort this
var data = [
    { count: '12', year: '1956' },
    { count: '1', year: '1971' },
    { count: '33', year: '1989' },
    { count: '33', year: '1988' }
];
//to get this
var data = [
    { count: '1', year: '1971' },
    { count: '12', year: '1956' },
    { count: '33', year: '1988' },
    { count: '33', year: '1989' },
];

Answer 1

( See the jsfiddle )

var data = [
    { count: '12', year: '1956' },
    { count: '1', year: '1971' },
    { count: '33', year: '1989' },
    { count: '33', year: '1988' }
];

console.log(data.sort(function (x, y) {
    var n = x.count - y.count;
    if (n !== 0) {
        return n;
    }

    return x.year - y.year;
}));
