javascript - 将其放入函数JS

Question

有一个条件，但是很麻烦，怎么减少呢？或者编写一个函数，将有一个上诉。

if (obj.Language.code == "ru") {
        if (obj.Tariff.typeCalc != 1) {
            if (obj.Price.Discount) {
                t = t + getText(obj.Language.code, 'PriceWithDiscount', [Round(obj.Price.Itog), final_currency]);
            }
            else {
                t = t + getText(obj.Language.code, 'PriceNoDiscount', [Round(obj.Price.Itog), final_currency]);
            }
        }
        else {
            if (obj.Price.Discount) {
                t = t + getText(obj.Language.code, 'PriceWithDiscount', [Round(obj.Price.Itog), obj.Currency.symbol]);
            }
            else {
                t = t + getText(obj.Language.code, 'PriceNoDiscount', [Round(obj.Price.Itog), obj.Currency.symbol]);
            }
        }

设计

if (obj.Language.code == "ru") {
}
else {
}

会经常见面，不想堆积

if (obj.Language.code == "ru") {
            if (obj.Price.Discount) {
                
                t = t + getText(obj.Language.code, 'PriceWithDicountOutCity', [obj.Price.Itog, final_currency, Round(obj.Len.value, final_currency), nextkmprice]);
            }
            else {
                
                t = t + getText(obj.Language.code, 'PriceOutCity', [obj.Price.Itog, final_currency, Round(obj.Len.value, final_currency), nextkmprice]);
            }
        }
        else {
            if (obj.Price.Discount) {
                
                t = t + getText(obj.Language.code, 'PriceWithDicountOutCity', [obj.Price.Itog, obj.Currency.symbol, Round(obj.Len.value, obj.Currency.symbol), nextkmprice]);
            }
            else {
                
                t = t + getText(obj.Language.code, 'PriceOutCity', [obj.Price.Itog, obj.Currency.symbol, Round(obj.Len.value, obj.Currency.symbol), nextkmprice]);
            }
        }

Answer 1

您可以采用单个外部检查和两个条件。

if (obj.Tariff.typeCalc != 1) {
    t += getText(
        obj.Language.code,
        obj.Price.Discount ? 'PriceWithDiscount' : 'PriceNoDiscount',
        [
            Round(obj.Price.Itog),
            obj.Language.code == "ru" ? final_currency : obj.Currency.symbol
        ]
    );
}

对于最后一个问题，您可以预先存储currency并使用变量而不是多个条件语句。

var currency = obj.Language.code == "ru" ? final_currency : obj.Currency.symbol;

t += getText(
    obj.Language.code,
    obj.Price.Discount ? 'PriceWithDicountOutCity' : 'PriceOutCity',
    [
        obj.Price.Itog,
        currency,
        Round(obj.Len.value, currency),
        nextkmprice
    ]
);
