es6 将数组中的 del 0 createBy GW00281461 createTime 2023-09-20 103714 updateBy GW00281461 updateTime 2023-09-20 103714 id 361 quotationConfirmId 141

可以使用ES6的数组方法map()来遍历数组中的每个对象，并将customerAnnualReductionRate和supplierAnnualReductionRate转换为百分数的小数形式。

const data = [
    {
        "del": 0,
        "createBy": "GW00281461",
        "createTime": "2023-09-20 10:37:14",
        "updateBy": "GW00281461",
        "updateTime": "2023-09-20 10:37:14",
        "id": 361,
        "quotationConfirmId": 141,
        "predictionYear": "2022",
        "output": 20000,
        "supplierAnnualReductionRate": "77",
        "customerAnnualReductionRate": "55",
        "netProfit": "983221278430.00",
        "unitPrice": 90000000,
        "netProfitMargin": -0.010115445251337448,
        "sort": 1,
        "jgPlaceName": "徐水工厂",
        "directMaterial": 339.55,
        "directMaterialAll": -516116000,
        "productionCost": 5163454.209999999,
        "otherCost": null,
        "profitCoefficient": null,
        "salesVolume": -97200000000000,
        "otherCosts": 103785200199.99998,
        "operatingProfit": -97303269084200
    },
    // ... other objects
];

const convertedData = data.map(obj => ({
    ...obj,
    customerAnnualReductionRate: parseFloat(obj.customerAnnualReductionRate) / 100,
    supplierAnnualReductionRate: parseFloat(obj.supplierAnnualReductionRate) / 100
}));

console.log(convertedData);

这样，数组中的每个对象的customerAnnualReductionRate和supplierAnnualReductionRate属性都会被转换为百分数的小数形式。
