javascript - 如何在javascript中过滤和添加剩余的obj

Question

我想知道如何修改 Javascript 中的特定对象，

我能够根据过滤器获取对象，但如何将未过滤 ID 的“`` 'in'='bank' 和 'out'='bank' 添加到过滤对象的末尾

如果 in 和 out 是 'bank'，

'bank' 应该是默认值，in 是 'credit' 而 out 是 'bank' 而 id 是 'trans'，然后过滤掉'trans'，把剩下的in，out，bank 和 ids 如图所示。

function getValue(send,receive, id){
 const temp = obj.map(e => Object.entries(e).map(([k, val]) => val)).flat(3)
    this.selectedProviderList = temp.filter(x=>x.in== send && x.in ==receive && x.id==id);
}

getValue("credit", "bank", "trans");

var obj = [{
    "btob": [{
      "id": "trans",
      "in": "bank",
      "out": "bank",
      "value": 10
    },{
      "id": "fund",
      "in": "bank",
      "out": "bank",
      "value": 10
    }],
    "ctob": [{
      "id": "trans",
      "in": "credit",
      "out": "bank",
      "value": 20
    },{
      "id": "fund",
      "in": "credit",
      "out": "bank",
      "value": 10
    }]
}]

例如，如果 in 是 'credit' 并且 out 是 'bank' 并且id 是 'trans'。

// Expected Output
[
   {
      "id": "trans",
      "in": "credit",
      "out": "bank",
      "value": 20
    },
    {
      "id": "fund",
      "in": "bank",
      "out": "bank",
      "value": 10
    }
]

// get the values if 'in' is 'debit' and 'out' is 'bank' and id is "fund" 

[{
      "id": "trans",
      "in": "bank",
      "out": "bank",
      "value": 10
    },{
      "id": "fund",
      "in": "debit",
      "out": "bank",
      "value": 10
    }]

// get the values if 'in' is 'bank' and 'out' is bank and id is "trans"

  [{
      "id": "trans",
      "in": "bank",
      "out": "bank",
      "value": 10
    },{
      "id": "fund",
      "in": "bank",
      "out": "bank",
      "value": 10
    }]

如果你能够转换你的对象，那么一步过滤器就可以做到这一点

var obj = [
        {
          "id": "trans",
          "in": "bank",
          "out": "bank",
          "value": 10
        },
        {
          "id": "fund",
          "in": "bank",
          "out": "bank",
          "value": 10
        },
       {
          "id": "trans",
          "in": "credit",
          "out": "bank",
          "value": 20
        },
        {
          "id": "fund",
          "in": "credit",
          "out": "bank",
          "value": 10
        }
    ]
// get the values if in is 'credit' and out is 'bank' and  id is 'trans'
 let resOne=obj.filter((givenObj)=>{
if(givenObj.in=="credit"&&givenObj.out=="bank"&&givenObj.id == "trans"){
  return givenObj
}
 })
  console.log(resOne)
 
 
 //// get the values if 'in' is 'debit' and 'out' is 'bank' and id is "fund" 
  let resTwo=obj.filter((givenObj)=>{
if(givenObj.in=="debit"&&givenObj.out=="bank"&&givenObj.id == "fund"){
  return givenObj
}
 })
   console.log(resTwo)
   
   
   //// get the values if 'in' is 'bank' and 'out' is bank and id is "trans"
    let resThree=obj.filter((givenObj)=>{
if(givenObj.in=="bank"&&givenObj.out=="bank"&&givenObj.id == "trans"){
  return givenObj
}
 })
   console.log(resThree)
