按自定义顺序对对象数组进行排序

Question

我有一个对象数组，这些对象的属性称为“ CODE”。

[
  {
   ID: 168,
   NAME: "First name",
   CODE: "AD"
  },
  {
   ID: 167,
   NAME: "Second name",
   CODE: "CC"
  },
  {
   ID: 169,
   NAME: "Third name",
   CODE: "CCM"
  },
  {
   ID: 170,
   NAME: "Fourth name",
   CODE: "CR"
  },
]

如何通过自定义顺序对数组进行排序，例如：

var item_order = ["CCM","CR","AD","CC"];

尝试各种方法均未成功。请帮忙。

Answer 1

您可以将函数sort与函数一起使用indexOf。

var array = [  {   ID: 168,   NAME: "First name",   CODE: "AD"  },  {   ID: 167,   NAME: "Second name",   CODE: "CC"  },  {   ID: 169,   NAME: "Third name",   CODE: "CCM"  },  {   ID: 170,   NAME: "Fourth name",   CODE: "CR"  }],

    item_order = ["CCM","CR","AD","CC"];



array.sort((a, b) => item_order.indexOf(a.CODE) - item_order.indexOf(b.CODE));



console.log(array);


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