javascript - 如果javascript中所有值都为空，如何删除对象？

Question

我在数组中有多个对象。它在对象中具有带有 value 属性的 values 数组。当所有值属性都为空时。我想删除整个对象。

我试过了，但我无法产生输出。请帮助我。

var data = [
  {
    "field": "surname",
    "values": [
      {
        "id": "drivingLicenseFront",
        "value": "",
        "isAvailable": true
      },
      {
        "id": "passport",
        "value": "",
        "isAvailable": true
      }
    ],
    "status": "passed"
  },
  {
    "field": "given names",
    "values": [
      {
        "id": "drivingLicenseFront",
        "value": "",
        "isAvailable": true
      },
      {
        "id": "passport",
        "value": "",
        "isAvailable": true
      }
    ],
    "status": "passed"
  },
  {
    "field": "date of birth",
    "values": [
      {
        "id": "drivingLicenseFront",
        "value": "25.07.1974",
        "isAvailable": true
      },
      {
        "id": "passport",
        "value": "05 JUN /JOIN 57",
        "isAvailable": true
      }
    ],
    "status": "passed"
  }
];

 for (let x = data.length-1; x >= 0; x--) {
            let count = 1;
            var dataValueLength = data[x].values.length;
            for (let y = 0; y < data[x].values.length; y++) {
                if (data[x].values[y].value === "") {
                    count++;
                }
            }
            if (dataValueLength == count) {
                data.splice(x, 1)
            }
        }
        
        console.log(JSON.stringify(data));

在上面的场景中，输出应该只有一个对象，即“出生日期”。

非常接近，只有一个问题(您正在将 count 初始化为 1 而不是 0)，使它

let count = 0;

演示

var data = [{
    "field": "surname",
    "values": [{
        "id": "drivingLicenseFront",
        "value": "",
        "isAvailable": true
      },
      {
        "id": "passport",
        "value": "",
        "isAvailable": true
      }
    ],
    "status": "passed"
  },
  {
    "field": "given names",
    "values": [{
        "id": "drivingLicenseFront",
        "value": "",
        "isAvailable": true
      },
      {
        "id": "passport",
        "value": "",
        "isAvailable": true
      }
    ],
    "status": "passed"
  },
  {
    "field": "date of birth",
    "values": [{
        "id": "drivingLicenseFront",
        "value": "25.07.1974",
        "isAvailable": true
      },
      {
        "id": "passport",
        "value": "05 JUN /JOIN 57",
        "isAvailable": true
      }
    ],
    "status": "passed"
  }
];

for (let x = data.length - 1; x >= 0; x--) {
  let count = 0; //Observe change in this line 
  var dataValueLength = data[x].values.length;
  for (let y = 0; y < data[x].values.length; y++) {
    if (data[x].values[y].value === "") {
      count++;
    }
  }
  if (dataValueLength == count) {
    data.splice(x, 1)
  }
}

console.log(JSON.stringify(data));
