// 1. 定義各國匯率 (2026 參考匯率，可自行調整)
const exchangeRates = {
    '大阪': { cur: 'JPY', rate: 0.21, sign: '¥' },
    '京都': { cur: 'JPY', rate: 0.21, sign: '¥' },
    '神戶': { cur: 'JPY', rate: 0.21, sign: '¥' },
    '曼谷': { cur: 'THB', rate: 0.92, sign: '฿' },
    '清邁': { cur: 'THB', rate: 0.92, sign: '฿' },
    '檳城': { cur: 'MYR', rate: 7.10, sign: 'RM' }
};

// 2. 換算器用的響應式變數
const inputAmount = ref(100);

// 3. 根據目前選取的城市取得匯率資訊
const currentRateInfo = computed(() => {
    return exchangeRates[currentCity.value] || { cur: 'JPY', rate: 0.21, sign: '¥' };
});

// 4. 計算結果
const twdResult = computed(() => {
    return (inputAmount.value * currentRateInfo.value.rate).toLocaleString(undefined, {maximumFractionDigits: 0});
});
