js将时间戳转换日期格式

function timestampToDate(timestamp) {
    const date = new Date(timestamp);

    // 格式化为 YYYY-MM-DD
    const year = date.getFullYear();
    const month = String(date.getMonth() + 1).padStart(2, '0');
    const day = String(date.getDate()).padStart(2, '0');
    const formattedDate = `${year}-${month}-${day}`;

    return formattedDate;
}

// 示例使用
const timestamp = Date.now(); // 获取当前时间的时间戳
console.log(timestampToDate(timestamp)); // 输出格式化的日期

const timestampInSeconds = 1633086000; // 假设这是一个以秒为单位的时间戳
const timestampInMilliseconds = timestampInSeconds * 1000;
console.log(timestampToDate(timestampInMilliseconds));

const month = String(date.getMonth() + 1).padStart(2, '0');
const day = String(date.getDate()).padStart(2, '0');
