檢查反應js中至少一個條件是否為真

Question

我有一個 object tableRows 數組。

tableRows = [
    {
        purchase_sales:1000,
        yearFirstRemAmount: 1456,
        capitalServicePurchase:123234,
        otherServicePurchase: 12323,
        otherStuffPurchase: 8903,
        capitaStuffPurchase: 1200,
        currentYearServiceSell: 47856,
        currentYearStuffSell: 100000,
        yearLastRemAmount: 20000
    }
    {
        purchase_sales:23430,
        yearFirstRemAmount: 12500,
        capitalServicePurchase: 1000010,
        otherServicePurchase: 12360,
        otherStuffPurchase: 12300,
        capitaStuffPurchase: 12000,
        currentYearServiceSell: 123123,
        currentYearStuffSell: 12111,
        yearLastRemAmount: 13120
    }
]

如何檢查每個索引的 9 個密鑰對值中的至少一個是否大於或等於 100000。

下面的代碼不起作用：

const handleValidation = (index)=>{
    if(tableRows[index].purchase_sales<100000 || tableRows[index].yearFirstRemAmount<100000 || tableRows[index].capitalServicePurchase<100000 || tableRows[index].otherServicePurchase<100000 || tableRows[index].otherStuffPurchase<100000 || tableRows[index].capitaStuffPurchase<100000 || tableRows[index].currentYearServiceSell<100000 || tableRows[index].currentYearStuffSell<100000 || tableRows[index].yearLastRemAmount<100000 ){
                alert("'At least one amount should be greater than or equal to 100000!!!")
            }
}

有沒有更好更簡潔的方法來實現這一點？

Answer 1

您可以結合使用map和some ：

const threshold = 1000000;
const yourAnswer = tableRows.map(Object.values).some(value => value >= threshold);

Answer 2

const handleValidation = (index)=>{
 
 if (Object.values(tableRows[index]).some(value => value < 100000)) {
    alert("'At least one amount should be greater than or equal to 100000!!!")
  }
}

Answer 3

您可以使用filter方法過濾數組， Object.values每個 object 的鍵值，以及some檢查是否存在等於或大於100000的鍵

 const tableRows = [ { purchase_sales:1000, yearFirstRemAmount: 1456, capitalServicePurchase:123234, otherServicePurchase: 12323, otherStuffPurchase: 8903, capitaStuffPurchase: 1200, currentYearServiceSell: 47856, currentYearStuffSell: 100000, yearLastRemAmount: 20000 }, { purchase_sales:23430, yearFirstRemAmount: 12500, capitalServicePurchase: 1000010, otherServicePurchase: 12360, otherStuffPurchase: 12300, capitaStuffPurchase: 12000, currentYearServiceSell: 123123, currentYearStuffSell: 12111, yearLastRemAmount: 13120 } ] const rows = tableRows.filter(row => { return Object.values(row).some(value => value >= 100000) }) console.log(rows)

Answer 4

如果您已經知道tableRows[index]的所有條目都是要檢查的數字，則可以使用Object.prototype.values和Array.prototype.some （這也是短路）

 const tableRows=[{purchase_sales:1000,yearFirstRemAmount:1456,capitalServicePurchase:123234,otherServicePurchase:12323,otherStuffPurchase:8903,capitaStuffPurchase:1200,currentYearServiceSell:47856,currentYearStuffSell:100000,yearLastRemAmount:20000},{purchase_sales:23430,yearFirstRemAmount:12500,capitalServicePurchase:1000010,otherServicePurchase:12360,otherStuffPurchase:12300,capitaStuffPurchase:12000,currentYearServiceSell:123123,currentYearStuffSell:12111,yearLastRemAmount:13120},{purchase_sales:0,yearFirstRemAmount:0,capitalServicePurchase:0,otherServicePurchase:0,otherStuffPurchase:0,capitaStuffPurchase:0,currentYearServiceSell:0,currentYearStuffSell:0,yearLastRemAmount:0}]; const handleValidation = (index) => { if (.Object.values(tableRows[index]).some((v) => v >= 100000)) { alert("'At least one amount should be greater than or equal to 100000,;! for index " + index) } } tableRows.forEach((_row, idx) => handleValidation(idx));

Answer 5

如其他答案中所述，您可以將 object 轉換為數組或將其值轉換為數組，然后在數組上使用some方法。

但是如果您的 object 可能有其他鍵並且您想檢查特定屬性：

1. 您可以創建要檢查的鍵數組：

const keys = [
    'purchase_sales',
    'yearFirstRemAmount',
    'capitalServicePurchase',
    'otherServicePurchase',
    'otherStuffPurchase',
    'capitaStuffPurchase',
    'currentYearServiceSell',
    'currentYearStuffSell',
    'yearLastRemAmount'
];

2. 創建一個 function 接收 object 作為輸入並驗證

function validate (obj) {
    for (key of keys) {
        if(obj[key] >= 100000) {
            // Do something here.
            // For instance: return true;
        }
    }
    // There is no property with a value greater or equal to 100000.
    // Do something here.
    // For instance: return false;
}

3. 驗證您的數據。 像這樣的東西：

    const isValid = tableRows.map(validate).every(Boolean)

Answer 6

const tableRows = [
{
    purchase_sales:1000,
    yearFirstRemAmount: 1456,
    capitalServicePurchase:123234,
    otherServicePurchase: 12323,
    otherStuffPurchase: 8903,
    capitaStuffPurchase: 1200,
    currentYearServiceSell: 47856,
    currentYearStuffSell: 100000,
    yearLastRemAmount: 20000
},
{
    purchase_sales:23430,
    yearFirstRemAmount: 12500,
    capitalServicePurchase: 1000010,
    otherServicePurchase: 12360,
    otherStuffPurchase: 12300,
    capitaStuffPurchase: 12000,
    currentYearServiceSell: 123123,
    currentYearStuffSell: 12111,
    yearLastRemAmount: 13120
}
];

const handleValidation = (index) => {
  const found = Object.values(tableRows[index]).some((x) => x > 100000);
  if(!found)
  {
    alert("'At least one amount should be greater than or equal to 100000!!!");
  }
  console.log(index,found)
}

tableRows.forEach((item, index) => handleValidation(index));

Answer 7

const tableRows = [
    {
        purchase_sales:1000,
        yearFirstRemAmount: 1456,
        capitalServicePurchase:123234,
        otherServicePurchase: 12323,
        otherStuffPurchase: 8903,
        capitaStuffPurchase: 1200,
        currentYearServiceSell: 47856,
        currentYearStuffSell: 100000,
        yearLastRemAmount: 20000
    },
    {
        purchase_sales:23430,
        yearFirstRemAmount: 12500,
        capitalServicePurchase: 1000010,
        otherServicePurchase: 12360,
        otherStuffPurchase: 12300,
        capitaStuffPurchase: 12000,
        currentYearServiceSell: 123123,
        currentYearStuffSell: 12111,
        yearLastRemAmount: 13120
    }
];
let data = tableRows.filter((row)=>{
   return Object.values(row).map(value => value >= 100000)
});
console.log(data);
