js抢红包源代码

// 假设红包总金额为 totalAmount，红包数量为 totalCount
let totalAmount = 100;  // 总金额
let totalCount = 10;   // 红包个数

// 生成每个红包的金额
function generateRedPackets(totalAmount, totalCount) {
    let redPackets = [];
    let remainAmount = totalAmount;
    let remainCount = totalCount;

    for (let i = 0; i < totalCount - 1; i++) {
        // 随机生成一个金额，保证每个红包金额在 0.01 到 remainAmount / remainCount * 2 之间
        let amount = parseFloat((Math.random() * (remainAmount / remainCount * 2 - 0.01) + 0.01).toFixed(2));
        redPackets.push(amount);
        remainAmount -= amount;
        remainCount--;
    }

    // 最后一个红包直接分配剩余金额
    redPackets.push(parseFloat(remainAmount.toFixed(2)));

    return redPackets;
}

let redPackets = generateRedPackets(totalAmount, totalCount);
console.log(redPackets);
