javascript - 使用 JavaScript 对对象进行排序和数组

Question

我有以下数组，需要按国家/地区的字母顺序排序:

data=[
    {
        "country": "China",
        "brands": {
            "abc": "123",
            "def": "123",
        },
        "day": "2020-04-16",
        "time": "2020-04-16T14:30:05+00:00"
    },
    {
        "country": "Zimbawe",
        "brands": {
            "abc": "123",
            "def": "123",
        },
        "day": "2020-04-16",
        "time": "2020-04-16T14:30:05+00:00"
    },
    {
        "country": "Africa",
        "brands": {
            "abc": "123",
            "def": "123",
        },
        "day": "2020-04-16",
        "time": "2020-04-16T14:30:05+00:00"
    }
]

到目前为止我已经尝试过:

data.sort()

还有这个:

function(a, b){return a - b}

但它仍然返回与原始数组相同的顺序。那么如何以国家/地区为基础对此进行排序呢？

Answer 1

使用排序方法

const data=[{"country": "China","brands": {"abc": "123","def": "123",},"day": "2020-04-16","time": "2020-04-16T14:30:05+00:00"},{"country": "Zimbawe","brands": {"abc": "123","def": "123",},"day": "2020-04-16","time": "2020-04-16T14:30:05+00:00"},{"country": "Africa","brands": {"abc": "123","def": "123",},"day": "2020-04-16","time": "2020-04-16T14:30:05+00:00"}];

data.sort((a, b) => a.country > b.country ? 1 : -1);

console.log(data);

.as-console-wrapper {min-height: 100% !important; top: 0;}
