js将毫秒数转换为天数、小时数、分钟数和秒数的计算方法

function formatDuring(millisecond) {
    var days = parseInt(millisecond / (1000 * 60 * 60 * 24));
    var hours = parseInt((millisecond % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
    var minutes = parseInt((millisecond % (1000 * 60 * 60)) / (1000 * 60));
    var seconds = (millisecond % (1000 * 60)) / 1000;
    return days + " 天 " + hours + " 小时 " + minutes + " 分钟 " + seconds + " 秒 ";
}
