JavaScript - 基于特殊订单的属性对对象数组进行排序

Question

我有一个具有多个属性的对象数组.给出以下数组:

var people = [
      {name: "allen", age: 33, color:"green"},
      {name: "jon", age: 23, color:"blonde"},
      {name: "silver", age: 54, color:"yellow"},
      {name: "james", age: 52, color:"grey"},
      {name: "flint", age: 25, color:"pink"},
      {name: "beilly", age: 31, color:"blonde"},
      {name: "bwones", age: 47, color:"grey"},
      {name: "sas", age: 35, color:"green"},
      {name: "jackson", age: 234, color:"yellow"},
      {name: "leonsardo", age: 12, color:"brown"},
      {name: "dicaeprio", age: 73, color:"pink"},
      {name: "sylvfester", age: 35, color:"blonde"},
      {name: "alleen2", age: 33, color:"green"},
      {name: "jofn2", age: 23, color:"blonde"},
      {name: "sdilver2", age: 54, color:"yellow"},
      {name: "jamaes2", age: 52, color:"grey"}
    ];

我需要通过color属性对这个数组进行排序,但是以一种特殊的方式排序,首先是by green,然后是by yellow,然后是brownby pink,然后是grey最后一个blonde.我在这里和这里阅读,但很难根据我的需要生成压实机.由于这只是一个演示阵列而我的真实数据将是一个更大的数组,因此排序机制应该比它更快 n^2.

这是你的比较器

var sortOrder = {green: 0, yellow: 1, brown: 2, pink: 3, grey: 4, blonde: 5};

people.sort(function (p1, p2) {
   return sortOrder[p1.color] - sortOrder[p2.color];
});
