javascript - 使用另一个数组对固定的对象数组进行排序

Question

我有定义对象顺序的变量，如下所示:

const order = ['large', 'medium', 'small'];

我想使用顺序数组中的名称来匹配数据数组对象的顺序:

const data = [{name: "small", children: []}, {name: "medium", children: []}, {name: "large", children: []}]

所以效果应该如下:

const data = [{name: "large", children: []}, {name: "medium", children: []}, {name: "small", children: []}]

我怎样才能做到这一点？

Answer 1

我们可以通过使用订单数组中name的索引来做到这一点:

const order = ['large', 'medium', 'small'];
const data = [{name: "small", children: []}, {name: "medium", children: []}, {name: "large", children: []}];

const sortArray = (arr, order) => {
  return data.sort((a, b) => order.indexOf(a.name) - order.indexOf(b.name)); 
}
console.log(sortArray(data, order));
