javascript - 对数组内的 json 数组进行排序

Question

我在一个数组中有多个 json 数组。我需要按名称优先和项目按升序对 json 数组进行排序。

var result = [[{"name":"james","item":"car"....],[{"name":"adrian","item":"car"....}],[{"name":"adrian","item":"truck"...}]]

 result.sort(function(a, b) {
    return (a.name).localeCompare(b.name)  ||  (a.item).localeCompare(b.item);
});

Output desired: [ [{"name":"adrian","item":"car"}],[{"name":"adrian","item":"truck"}],[{"name":"james","item":"car"}] ]

Answer 1

我认为你很接近。因为它是数组中的数组，所以使用它

var result = [[{"name":"james","item":"car"}],[{"name":"adrian","item":"car"}],[{"name":"adrian","item":"truck"}]];

 result.sort(function(a, b) {
    return (a[0].name).localeCompare(b[0].name)  ||  (a[0].item).localeCompare(b[0].item);
});

测试结果:

console.log(JSON.stringify(result));

=>

[[{"name":"adrian","item":"car"}],[{"name":"adrian","item":"truck"}],[{"name":"james","item":"car"}]]
