比較2個陣列并從一個陣列到另一個陣列中查找屬性值-有解無憂

我有下面提到的 2 個陣列。

const arr1 = [{ Id: "a153O000001mjD1QAI", Document_ID__c: 176767 }];


const arr2 = [
  {
    classification: "Scientific Response",
    core_san_localization_translation: ["No"],
    core_san_verbal_only: "false",
    id: "176767",
    major_version_number: "1",
    minor_version_number: "0",
    name: "Advance Search Doc_General Information",
    response_type: ["General"],
    size: 70953,
    subtype: "Local",
    title: "Advance Search Doc_General Information",
    type: "Medical Information",
  },

  {
    classification: "Scientific Response",
    core_san_localization_translation: ["No"],
    core_san_verbal_only: "false",
    id: "127462",
    major_version_number: "1",
    minor_version_number: "0",
    name: "APPROVAL verdict APPROVED FOR USE",
    response_type: ["Administration"],
    size: 1362339,
    subtype: "Local",
    title: "ahsdjhsahdasld",
    type: "Medical Information",
  },

  {
    classification: "Scientific Response",
    core_san_localization_translation: ["No"],
    core_san_verbal_only: "false",
    id: "127461",
    major_version_number: "2",
    minor_version_number: "0",
    name: "APPROVAL verdict APPROVED ,MINOR CHANGES",
    response_type: ["Administration"],
    size: 1362339,
    subtype: "Local",
    title: "ahsdjhsahdasld",
    type: "Medical Information",
  },

  {
    classification: "Scientific Response",
    core_san_answer: "Dosage",
    core_san_localization_translation: ["No"],
    core_san_verbal_only: "false",
    id: "176776",
    major_version_number: "1",
    minor_version_number: "0",
    name: "General Info Test 2",
    response_type: ["Pharmacokinetics and Pharmacodynamics"],
    size: 25432,
    subtype: "Local",
    title: "General Info Test 2",
    type: "Medical Information",
  },
];

我想從 arr2 中的 arr1 搜索屬性“Document_ID__c”的值，如果它與 arr2 中任何元素上的“176767”匹配，只需創建一個新陣列并存盤該元素。

例如，我想要的輸出是

const finalarray = [
  {
    classification: "Scientific Response",
    core_san_localization_translation: ["No"],
    core_san_verbal_only: "false",
    id: "176767",
    major_version_number: "1",
    minor_version_number: "0",
    name: "Advance Search Doc_General Information",
    response_type: ["General"],
    size: 70953,
    subtype: "Local",
    title: "Advance Search Doc_General Information",
    type: "Medical Information",
  },
];

請幫助我。

嘗試這個：

let mArray = []


for (i in arr1) {
    for (j in arr2){
      if (arr1[i].Document_ID__c == arr2[j].id) {
         mArray.push(arr2[j])
      }
    }
}

console.log(mArray);

你可以試試這個：

var newObj = arr1.map(j =>{
  return  arr2.filter(e=>{
       return e.id == j.Document_ID__c
   })

 console.log(newObj)

const finalArray = arr2.filter((a) => arr1.some((b) => a.id == b.Document_ID__c));
console.log(finalArray);

uj5u.com熱心網友回復：

您可以使用Array.some()方法來測驗陣列中的至少一個元素是否通過了提供的函式實作的測驗。

作業演示：

const arr1 = [{ Id: "a153O000001mjD1QAI", Document_ID__c: 176767 }];

const arr2 = [{
    classification: "Scientific Response",
    core_san_localization_translation: ["No"],
    core_san_verbal_only: "false",
    id: "176767",
    major_version_number: "1",
    minor_version_number: "0",
    name: "Advance Search Doc_General Information",
    response_type: ["General"],
    size: 70953,
    subtype: "Local",
    title: "Advance Search Doc_General Information",
    type: "Medical Information",
}, {
    classification: "Scientific Response",
    core_san_localization_translation: ["No"],
    core_san_verbal_only: "false",
    id: "127462",
    major_version_number: "1",
    minor_version_number: "0",
    name: "APPROVAL verdict APPROVED FOR USE",
    response_type: ["Administration"],

    core_san_localization_translation: ["No"],
    core_san_verbal_only: "false",
    id: "127461",
    major_version_number: "2",
    minor_version_number: "0",
    name: "APPROVAL verdict APPROVED ,MINOR CHANGES",

}];

const result = arr2.filter((a) => arr1.some((b) => a.id.toString() === b.Document_ID__c.toString()));
console.log(result);

uj5u.com熱心網友回復：

只需使用JS 內置的陣列迭代方法就可以了：

var result = arr2.filter(function(o1){
    // filter out  items in result2
    return arr1.some(function(o2){
        return o1['id'] == o2['Document_ID__c']; 
    });
    });
