按两个值排序，优先考虑其中之一 [英] Sort by two values prioritizing on one of them

问题描述

我将如何按 count 和 year 值按升序对这些数据进行排序，优先于 count 值?

How would I sort this data by count and year values in ascending order prioritizing on the count value?

//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' },
];

推荐答案

(查看 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;
}));
