javascript - Javascript 中的总和格式金额返回 NaN

Question

我有一个字符串数组，每个数组值都采用货币格式:

var sells = ['INR1,433,200.00','INR5,750.00','INR12,000.00','INR1,905.00','INR235.00'];

我尝试循环遍历该数组的每个值，并将其求和以获得货币格式的总计

var total = 0;
sells.forEach(function(sell) {
    total += sell;
});
console.log(total);

当我看到浏览器控制台日志时，结果始终是 NaN ，我预计结果是 INR1,453,090.00

Answer 1

替换 INR 和逗号，并将 String 转换为 Number:

var sells = ['INR1,433,200.00','INR5,750.00','INR12,000.00','INR1,905.00','INR235.00'];

var total = 0;
sells.forEach(function(sell) {
    total += +sell.replace('INR','').replace(/,/g,'');
});
console.log(total);

您还可以使用reduce:

var sells = ['INR1,433,200.00', 'INR5,750.00', 'INR12,000.00', 'INR1,905.00', 'INR235.00'];
console.log(sells.reduce((acc, val) => acc + +val.replace('INR', '').replace(/,/g, ''), 0));
