Question

我正在尝试按下面的值以升序对数组中的对象进行排序，并获得所需的输出，如下所示： -

var arr = [{"DOA Qty":"0.000665921017598927382910198160","LOS%":"0","FID Valid EC By Part":"0.0041860443283016713761966","Interventions":"0"}]

所需输出 - 按值按升序排序：

var desiredarr =[{"LOS%":"0","Interventions":"0","DOA Qty":"0.000665921017598927382910198160","FID Valid EC By Part":"0.0041860443283016713761966"}]


let sorteddataarr: any = Object.values(arr[0]).sort(function (a, b) { return arr[a] - arr[b]; });

alert(JSON.stringify(sorteddataarr));  // not giving result

Answer 1

a[1]-b[1] == ：ASEC

b[1]-a[1] == ：DESC

试试这个：

var obj = 
{
	"DOA Qty":"0.000665921017598927382910198160",
	"LOS%":"0",
	"FID Valid EC By Part":"0.0041860443283016713761966",
	"Interventions":"0"
}

var entries = Object.entries(obj)
entries.sort(function(a,b){return a[1]-b[1]});

obj = {};
entries.map(function(item){
	obj[item[0]] = item[1];
})
console.log(obj);

也许以下内容会有所帮助，在执行Object.keys或for something in ...等操作时，对象的键不会按特定顺序给出，因为顺序对您很重要我转换了对象一个或多个键和值的数组：

var arr = [{"DOA Qty":"0.000665921017598927382910198160","LOS%":"0","FID Valid EC By Part":"0.0041860443283016713761966","Interventions":"0"}];

console.log(
  arr.map(
    object=>
      Object.keys(object).map(
        key=>[Number(object[key]),key]//your values are not numbers, maybe create better JSON
      ).sort(
        ([a],[b])=>a-b
      )
      //optional, if you rather have [key,value] .map(([value,key])=>[key,value]
  )
)
