Javascript分类对象数组排序[重复]答案

【问题描述】：

假设我有一个对象数组：

let array = [

    {id: 0, type: "Office" },
    {id: 1, type: "Security" },
    {id: 2, type: "Office" },
    {id: 3, type: "Security" },
    {id: 4, type: "Security" },
    {id: 5, type: "Office" },
    {id: 6, type: "Agent" },
    {id: 7, type: "Security" }

];

我需要根据自定义的分类序列集进行排序，即["Office", "Agent", "Security"] 得到以下输出：

var array = [
    {id: 0, type: "Office" },
    {id: 2, type: "Office" },
    {id: 5, type: "Office" },
    {id: 6, type: "Agent" }
    {id: 1, type: "Security" },
    {id: 3, type: "Security" },
    {id: 4, type: "Security" },
    {id: 7, type: "Security" }
];

没有找到任何合适的解决方案。

【解决方案1】：

您可以使用indexOf 获取排序顺序。

let array = [
    {id: 0, type: "Office" },
    {id: 1, type: "Security" },
    {id: 2, type: "Office" },
    {id: 3, type: "Security" },
    {id: 4, type: "Security" },
    {id: 5, type: "Office" },
    {id: 6, type: "Agent" },
    {id: 7, type: "Security" }
];
const order = ["Office", "Agent", "Security"]
array.sort((a,b)=>order.indexOf(a.type)-order.indexOf(b.type));
console.log(array);
