更改JavaScript对象键和数据的位置 [英] Change position of JavaScript object key and data

问题描述

我正在处理javascript对象.我想按特定顺序将数据传递到下一个数组.就像我得到这样的数据

I am working on javascript object. And I want to pass data to next array in a specific sequence. like I get data like this

var obj = [{
  0: "Owner Name"
  1: "Mailing Address"
  2: "Situs Address"
  3: "APN"  
}]

并希望此序列像这样

var obj = [{
  3: "APN"  
  0: "Owner Name"
  2: "Situs Address"  
  1: "Mailing Address" 
}];

是否有可能基于数据?我不知道从数据库顺序可能会更改. 对于那些说我应该使用数组的人.我正在基于此对象获取数据，

Is it possible to do that, on bases of data? As I don't know from database sequence maybe change. edit: For those who are saying I should use array. I am getting data on basis of this object like,

 var data[{
  0:"CHANCE WILLIAM C & KATHRYN L"
  1:"P O BOX 7642 CHICO CA 95927"
  2:"LOT 4 PM 150-99/100"
  3:"040-310-086-000" }]

推荐答案

对象不具有排序属性

Object not have sorting property

所以您可以这样做

将数组对象的参数转换为单个对象.然后按键的dec顺序进行排序

Covert the array object arguments into individual object.then sorting with dec order of the key

var obj = [{
  '0': "Owner Name",
  '1': "Mailing Address",
  '2': "Situs Address",
  '3': "APN" ,
}];

var array = Object.keys(obj[0]).map(function(a){
                  return ({[a]:obj[0][a]});
}) //recreate with individual object

var sorted= array.sort((a,b)=> Object.keys(b)-Object.keys(a))
 console.log(sorted) //sorted  object
 
var res = sorted.map(a=> Object.values(a)[0]) // for array

console.log(res)
