如何根据键对对象数组进行排序并设置一个附加键，该键应在顺序更改时递增？

Question

我有一个数组，它应该根据 conditionalTo 进行排序，并根据序列设置索引，只要序列发生变化，索引就应该递增。完成后，我们需要在索引中基于 computationTo 再次对数组进行排序，只应进行二级排序

const array = 
[
{conditionalFrom: 102, conditionalTo: 112, computationFrom: 10, computationTo: 150},
{conditionalFrom: 0, conditionalTo: 100, computationFrom: 0, computationTo: 400},
{conditionalFrom: 10, conditionalTo: 100, computationFrom: 0, computationTo: 300},
{conditionalFrom: 0, conditionalTo: 110, computationFrom: 20, computationTo: 200},
{conditionalFrom: 12, conditionalTo: 112, computationFrom: 100, computationTo: 1000},
{conditionalFrom: 100, conditionalTo: 110, computationFrom: 1001, computationTo: 100000},
]

根据 conditionalTo 排序并为每个序列添加编号

const sorted = 
[
{conditionalFrom: 0, conditionalTo: 100, computationFrom: 0, computationTo: 400, sequece: 1},
{conditionalFrom: 10, conditionalTo: 100, computationFrom: 0, computationTo: 300, sequece: 1},
{conditionalFrom: 0, conditionalTo: 110, computationFrom: 20, computationTo: 200, sequece: 2},
{conditionalFrom: 100, conditionalTo: 110, computationFrom: 1001, computationTo: 100000, sequece: 2},
{conditionalFrom: 12, conditionalTo: 112, computationFrom: 100, computationTo: 1000, sequece: 3},
{conditionalFrom: 102, conditionalTo: 112, computationFrom: 10, computationTo: 150, sequece: 3},
]

根据 computationTo 和 sequence 排序

const sorted = 
[
{conditionalFrom: 0, conditionalTo: 100, computationFrom: 0, computationTo: 400},
{conditionalFrom: 0, conditionalTo: 110, computationFrom: 20, computationTo: 200},
{conditionalFrom: 10, conditionalTo: 100, computationFrom: 0, computationTo: 300},
{conditionalFrom: 12, conditionalTo: 112, computationFrom: 100, computationTo: 1000},
{conditionalFrom: 100, conditionalTo: 110, computationFrom: 1001, computationTo: 100000},
{conditionalFrom: 102, conditionalTo: 112, computationFrom: 10, computationTo: 150},
]

尝试了很多方法，包括 noramal sort lodash sortby orderby 但没有任何效果请帮助添加的序列实际上是一种解决方法，但实际上没有任何效果

 const SlabDetails = orderBy(this.tableData, [r => r.conditionalTo - r.conditionalFrom, r => r.computationTo - r.computationFrom], "asc");

你想的顺序错了。你可以先sort基于conditionalTo和computationTo的数组。然后，为每个对象添加一个sequence 属性。如果 conditionalTo 与前一个对象

不同，则增加它

const array =[{conditionalFrom:102,conditionalTo:112,computationFrom:10,computationTo:150},{conditionalFrom:0,conditionalTo:100,computationFrom:0,computationTo:400},{conditionalFrom:10,conditionalTo:100,computationFrom:0,computationTo:300},{conditionalFrom:0,conditionalTo:110,computationFrom:20,computationTo:200},{conditionalFrom:12,conditionalTo:112,computationFrom:100,computationTo:1000},{conditionalFrom:100,conditionalTo:110,computationFrom:1001,computationTo:100000},];

array.sort((a,b) => a.conditionalTo - b.conditionalTo || a.computationTo - b.computationTo)

let previous,
    sequence = 0;
    
for (const o of array) {
  if (o.conditionalTo !== previous) {
    ++sequence;
    previous = o.conditionalTo
  } 
  o.sequence = sequence
}

console.log(array)
