过滤对象以检查数组的所有元素是否存在

Question

我是键值对概念的新手，并试图找出一种方法来过滤所有具有数组所有元素的键值对，但我在循环中的某个地方被击中。

我的键值对：

Alltrips = {
    "20180301": [{
            "transporter": {
                "company": "Pradeep Transport",
                "id": 1518419163555
            },
            "vehicleRegistrationNumber": "AS01FF1234",
            "destinations": [{
                "Id": "pcwYK",
                "v": "Bhubaneswar, OD"
            }, {
                "Id": "fy3yF",
                "v": "Tiruppur, TN"
            }],
            "Owner": "Gogs"
        },
        {
            "transporter": {
                "company": "tes Transport",
                "id": 1518419163515
            },
            "vehicleRegistrationNumber": "AS01FF1454",
            "destinations": [{
                "Id": "coWoz",
                "v": "Vizag, AP"
            }, {
                "Id": "EZuh7",
                v: "Ambala Sadar, HR"
            }],
            "Owner": "Acme"
        }
    ],
    "20180406": [{
            "transporter": {
                "company": "tes Transport",
                "id": 15184195663555
            },
            "vehicleRegistrationNumber": "AS01FF1444",
            "destinations": [{
                "Id": "pcqYK",
                "v": "Coorg"
            }, {
                "Id": "fy3yF",
                "v": "Tiruppur, TN"
            }],
            "Owner": "pyu"
        }

    ],
    "20180412": [{
            "transporter": {
                "company": "tes Transport",
                "id": 15184195663555
            },
            "vehicleRegistrationNumber": "AS01FF1144",
            "destinations": [{
                "Id": "pcqYK",
                "v": "Coorg"
            }, {
                "Id": "fy3yF",
                "v": "Tiruppur, TN"
            }],
            "Owner": "ps"
        }

    ]


}

我有一个数组：

searchOptions= 
[{label: "tes cargo", value: "tes cargo", type: "TransporterType"}, {label: "AS01FF1444", value: "AS01FF1444", type: "VehicleType"},{label: "Coorg State, Kodagu Dist., Karnataka", value: "Coorg State, KA", type: "PlaceType"}]

我必须返回一个结果对象＆＃34; final ＆＃34;其中包含所有＆＃34; Alltrips ＆＃34;包含 searchOptions.value

的键值对

例如对于给定的数组＆＃34; searchOptions＆＃34;以上，我的结果＆＃34; final＆＃34;对象应该是：

final= {
"20180406": [{
            "transporter": {
                "company": "tes Transport",
                "id": 15184195663555
            },
            "vehicleRegistrationNumber": "AS01FF1444",
            "destinations": [{
                "Id": "pcqYK",
                "v": "Coorg"
            }, {
                "Id": "fy3yF",
                "v": "Tiruppur, TN"
            }],
            "Owner": "pyu"
        }

    ]

}

我尝试过的解决方案是：

var final={};
    var temp=[];
    for(var dates in this.alltrips) {
      if(dates>=mindate && dates <=maxdate) {
        for(var i=0;i<this.alltrips[dates].length; i++) {
          //for(let options in this.alltrips[dates][i]) {

            for(var j=0;j<searchOptions.length;j++) {

              if(searchOptions[j].type== "TransporterType") {
                var flag=true;
                if(searchOptions[j].value == this.alltrips[dates][i].transporter.company)
                  flag=true
                else {
                  flag=false
                }
              }
              else if(searchOptions[j].type== "VehicleType"){
                if(searchOptions[j].value == this.alltrips[dates][i].vehicleRegistrationNumber)
                  flag=true
                else 
                  flag=false
              }
              if(searchOptions[j].type== "PlaceType") {
                //if(this.alltrips[dates][i]== 'destinations') {
                  for(var k=0;k<this.alltrips[dates][i].destinations.length;k++){
                    if(searchOptions[j].value== this.alltrips[dates][i].destinations[k].v)
                      flag=true
                    else
                      flag=false
                  }
               // }
              }
              if(flag==true) {
                temp.push(this.alltrips[dates][i])

              }
              else 
                break;
                final[dates]= temp;
                temp=[]
            }
          //}

        }
      }
    }
    console.log(temp)
    console.log(final)

上面代码的问题是它只返回每个键的单个值，如：

{"20180406" :  Array(1)}

如果每个键有多个匹配，则只返回一个。例如，我可能会有一些匹配结果可能是：

{"20180406" : Array(2), "20180412" : Array(2)}

但是，对于任何匹配，它只返回一个数组匹配。我该如何解决？

编辑：我找到了答案并更新了主要功能。使用＆＃34;继续＆＃34;做了诀窍

var final = {};
      var temp = [];
      var flag=false;
      for (var dates in this.alltrips) {
        temp=[]
        if(dates >= mindate && dates <= maxdate) {
          loop1 : for (var i = 0; i < this.alltrips[dates].length; i++) {
            for(var j = 0; j < samplearray.length; j++) {
              if (samplearray[j].type == "VehicleType") {
                if (samplearray[j].value == this.alltrips[dates][i].vehicleRegistrationNumber) {
                flag=true;
                }
                else {
                  flag=false;
                  continue loop1;
                }
              } else if (samplearray[j].type == "TransporterType") {
                  if (samplearray[j].value == this.alltrips[dates][i].transporter.company) {
                    flag=true;
                  }
                  else{
                    flag= false;
                    continue loop1;
                  }
              } else if(samplearray[j].type == "PlaceType") {
                  for(var k=0;k< this.alltrips[dates][i].destinations.length;k++) {
                    if (samplearray[j].value == this.alltrips[dates][i].destinations[k].v) {
                      flag=true;
                    }
                    else {

                      continue loop1;
                    }
                  }
              } else if (samplearray[j].type == "OwnerType") {
                  if (samplearray[j].id == this.alltrips[dates][i].operatorId) {
                    flag=true;
                  }
                  else{
                    flag= false;
                    continue loop1;
                  }
               } 
            }
            if(flag==true) {
            temp.push(this.alltrips[dates][i])
            final[dates]= temp;
            }
          }
        }
      }
     console.log(final)

当然它并不匹配任何东西，但是如果你更改搜索过滤器以使其与Alltrips中的某些内容匹配则可以。 https://jsfiddle.net/zs8xmaLx/35/
