在javascript中顯示陣列的元素

我有一個陣列物件。

1,2,3,4 是標題索引。

我想分別提取每個標題的每個物件陣列

這是具有索引的物件及其作為物件陣列的相應值

Object {
  "1": Array [
    Object {
      "@SCHUM_HODSHI": "107250.13",
      "@TEUR": "?????? ??? ??????",
    },
    Object {
      "@SCHUM_HODSHI": "50.00",
      "@TEUR": "??? ????",
    },
    Object {
      "@SCHUM_HODSHI": "13652.67",
      "@TEUR": "?.??????",
    },
  ],
  "2": Array [
    Object {
      "@SCHUM_HODSHI": "182.55",
      "@TEUR": "????? ?????",
    },
  ],
  "3": Array [
    Object {
      "@SCHUM_HODSHI": "3200.00",
      "@TEUR": "????? ?????",
    },
  ],
  "4": Array [
    Object {
      "@SCHUM_HODSHI": "11250.00",
      "@TEUR": "????? ?'??'???",
    },
  ],
}

例如：--在第一個索引即1 下，
我想在物件陣列下方顯示，等等。

Array [
    Object {
      "@SCHUM_HODSHI": "107250.13",
      "@TEUR": "?????? ??? ??????",
    },
    Object {
      "@SCHUM_HODSHI": "50.00",
      "@TEUR": "??? ????",
    },
    Object {
      "@SCHUM_HODSHI": "13652.67",
      "@TEUR": "?.??????",
    },
  ],

請讓我知道要對此實施什么邏輯？

謝謝。

像這樣做：

//create empty array
let Array = []

//and this is your Object
const Obj = {
  "1": [
    {
      "@SCHUM_HODSHI": "107250.13",
      "@TEUR": "?????? ??? ??????",
    },
    {
      "@SCHUM_HODSHI": "50.00",
      "@TEUR": "??? ????",
    },
    {
      "@SCHUM_HODSHI": "13652.67",
      "@TEUR": "?.??????",
    },
  ],
  "2": [
    {
      "@SCHUM_HODSHI": "182.55",
      "@TEUR": "????? ?????",
    },
    {
      "@SCHUM_HODSHI": "182.55",
      "@TEUR": "????? ?????",
    },
  ],
  "3": [
    {
      "@SCHUM_HODSHI": "3200.00",
      "@TEUR": "????? ?????",
    },
  ],
  "4": [
    {
      "@SCHUM_HODSHI": "11250.00",
      "@TEUR": "????? ?'??'???",
    },
  ],
}

//now just push your Object to your Array
Array.push(Obj)
console.log("Array: ", Array)
//Below is the way you can get specific 1,2,3,4 index objects with the map function
Array.map(obj => console.warn("obj: ", obj[1]));

希望這對你有用。

此代碼將物件轉換為陣列。

const Obj = {
    1: [
        {
            "@SCHUM_HODSHI": "107250.13",
            "@TEUR": "?????? ??? ??????",
        },
        {
            "@SCHUM_HODSHI": "50.00",
            "@TEUR": "??? ????",
        },
        {
            "@SCHUM_HODSHI": "13652.67",
            "@TEUR": "?.??????",
        },
    ],
    2: [
        {
            "@SCHUM_HODSHI": "182.55",
            "@TEUR": "????? ?????",
        },
        {
            "@SCHUM_HODSHI": "182.55",
            "@TEUR": "????? ?????",
        },
    ],
    3: [
        {
            "@SCHUM_HODSHI": "3200.00",
            "@TEUR": "????? ?????",
        },
    ],
    4: [
        {
            "@SCHUM_HODSHI": "11250.00",
            "@TEUR": "????? ?'??'???",
        },
    ],
};

const idx = Object.keys(Obj).map((key) => {
    return parseInt(key) - 1;
});

// this will store the contents of the array you want
const newArray = Array(idx   1);

for (let index of idx) {
    newArray[index] = Obj[index   1][0];
}

/* store each array in new lists container */
const lists = Object.keys(obj).map((index) => {

/* iterate on each list */
lists.map((list) => console.log(...list));

讓我們以一種非常簡單和直接的方式來做。提取所有串列，將其保存到另一個變數中以備后用，然后進行迭代
