Question

我想用procedureName＆amp;过滤下面的json数据。 hospitalName基于GUI中的用户输入。

myObject= [
    {        
        "department": "Gynic",
        "treatmentList": [
            {
                "procedureName": "Bone Grafting",               
                "hospitalList": [
                    {
                        "hospitalName": "Renai",                        
                    },
                    {
                        "hospitalName": "Aster",                        
                    },
                    {
                        "hospitalName": "Appolo",                        
                    }
                ],                
            },
            {                
                "procedureName": "IVF",                
                "hospitalList": [
                    {
                        "hospitalName": "Renai",                        
                    }
                ],               
            }
        ]
    }
]

例如，当用程序名称＆＃39;骨移植＆＃39;过滤上述json时。＆安培;医院名称＆＃39; Renai＆＃39;我应该得到以下格式的结果。

     [
    {        
        "department": "Gynic",
        "treatmentList": [
            {
                "procedureName": "Bone Grafting",               
                "hospitalList": [
                    {
                        "hospitalName": "Renai",                        
                    },
                    {
                        "hospitalName": "Aster",                        
                    },
                    {
                        "hospitalName": "Appolo",                        
                    }
                ],                
            }
        ]
    }
]

我尝试使用以下代码。但它没有过滤json

var x = myObject.filter(function (obj) {
    return obj.treatmentList.some(function (item) {
        return item.procedureName == 'Bone Grafting';
    });
});

有人可以帮我纠正我的代码中的错误吗？

您需要遍历myObject阵列。
为some数组添加hospitalList函数的新调用，并与hospitalName属性进行比较。
最后将找到的匹配项添加到您的treatmentList数组。

＆＃13;

var myObject = [{
  "department": "Gynic",
  "treatmentList": [{
      "procedureName": "Bone Grafting",
      "hospitalList": [{
          "hospitalName": "Renai",
        },
        {
          "hospitalName": "Aster",
        },
        {
          "hospitalName": "Appolo",
        }
      ],
    },
    {
      "procedureName": "IVF",
      "hospitalList": [{
        "hospitalName": "Renai",
      }],
    }
  ]
}];

var myResultObject = [];

for (var i = 0; i < myObject.length; i++) {
  myResultObject.push({
    'department': myObject[i].department,
    'treatmentList': myObject[i].treatmentList.filter(function(obj) {
      return obj.procedureName === 'Bone Grafting' && obj.hospitalList.some(function(hn) {
        return hn.hospitalName === 'Renai';
      });
    })
  });
}

console.log(myResultObject);

不确定这是否是最好的方法，但你可以试试

＆＃13;

var myObject = [{
  "department": "Gynic",
  "treatmentList": [{
    "procedureName": "Bone Grafting",
    "hospitalList": [{
      "hospitalName": "Renai",
    }, {
      "hospitalName": "Aster",
    }, {
      "hospitalName": "Appolo",
    }],
  }, {
    "procedureName": "IVF",
    "hospitalList": [{
      "hospitalName": "Renai",
    }],
  }]
}];


function search(procedureName, hospitalName) {
  return myObject[0].treatmentList.filter(e => {
    if (e.procedureName === procedureName) {
      return e.hospitalList.filter(h => {
        return h.hospitalName === hospitalName
      })
    }
  })
}


console.log(search("IVF", "Renai"))

Array.some只需要数组中至少有一个元素通过测试。因此，过滤方法返回true而不过滤任何内容。

以下方式可以满足您的需求。

var x = myObject.map(function (obj) {
    obj.treatmentList = obj.treatmentList.filter(function (item) {
        return item.procedureName == 'Bone Grafting' &&
            item.hospitalList.some(function (hospital) {
                return hospital.hospitalName == 'Renai';
            });
    });
    return obj;
});
