如何再次创建动态变量和求和值以分配动态变量？

例如，

var incomeCr = 0, incomeDr = 0;

for (var j = 1; j <= noOfMonths; j++) 
{
    if(response[i]["AmountType" + j] == "Cr")
    {
        if(response[i]["ClosingBalanceWithType" + j] < 0)
        {
           response[i]["ClosingBalanceWithType" + j] = -1 * response[i]["ClosingBalanceWithType" + j];
        }
        incomeCr += parseFloat(response[i]["ClosingBalanceWithType" + j]);
    }
    else if (response[i]["AmountType" + j] == "Dr")
    {
        if (response[i]["ClosingBalanceWithType" + j] < 0)
        {
            response[i]["ClosingBalanceWithType" + j] = -1 * response[i]["ClosingBalanceWithType" + j];
        }
        incomeDr += parseFloat(response[i]["ClosingBalanceWithType" + j]);
    }
}

这里如何创建动态变量incomeCr1，incomeCr2 ...和incomeDr1，incomeDr2 ......并将值再次赋值给动态变量。

Answer 1

您不能像这样创建动态变量。而是使用数组：

var incomeCr = [];
//incomeCr[1], incomeCr[2],...
incomeCr[1] = "txt";
incomeCr[2] = "txt2";

var incomeCr = 0, incomeDr = 0, expenseCr = 0, expenseDr = 0, iIncomeCr = {}, eExpenseCr = {}, iIncomeDr = {}, eExpenseDr = {}, cr = [];
        for (var i = 0; i < response.length; i++) {
            // Sum Primary Group Income on each Month
            if (response[i].Type == "Ledger" && response[i].PrimaryGroup == "Incomes") {
                for (var j = 1; j <= noOfMonths; j++) {
                    if (response[i]["AmountType" + j] == "Cr") {
                        if (response[i]["ClosingBalanceWithType" + j] < 0) {
                            response[i]["ClosingBalanceWithType" + j] = -1 * response[i]["ClosingBalanceWithType" + j];
                        }
                        iIncomeCr["incomeCr" + j] = (iIncomeCr["incomeCr" + j] ? iIncomeCr["incomeCr" + j] : 0) + parseFloat(response[i]["ClosingBalanceWithType" + j]);
                        iIncomeDr["incomeDr" + j] = iIncomeDr["incomeDr" + j] ? iIncomeDr["incomeDr" + j] : 0;
                    } else if (response[i]["AmountType" + j] == "Dr") {
                        if (response[i]["ClosingBalanceWithType" + j] < 0) {
                            response[i]["ClosingBalanceWithType" + j] = -1 * response[i]["ClosingBalanceWithType" + j];
                        }
                        iIncomeDr["incomeDr" + j] = (iIncomeDr["incomeDr" + j] ? iIncomeDr["incomeDr" + j] : 0) + parseFloat(response[i]["ClosingBalanceWithType" + j]);
                        iIncomeCr["incomeCr" + j] = iIncomeCr["incomeCr" + j] ? iIncomeCr["incomeCr" + j] : 0;
                    }
                }
            }
