传入的时间戳为：83424000；
打印结果：
--------- 转换时间: 0天 23时 10分 24秒
函数返回结果：
23:10:24
实现代码：
var my_time = '83424000'; getDuration(my_time); function getDuration(my_time) { var days = my_time / 1000 / 60 / 60 / 24; var daysRound = Math.floor(days); var hours = my_time / 1000 / 60 / 60 - (24 * daysRound); var hoursRound = Math.floor(hours); var minutes = my_time / 1000 / 60 - (24 * 60 * daysRound) - (60 * hoursRound); var minutesRound = Math.floor(minutes); var seconds = my_time / 1000 - (24 * 60 * 60 * daysRound) - (60 * 60 * hoursRound) - (60 * minutesRound); console.log('转换时间:', daysRound + '天', hoursRound + '时', minutesRound + '分', seconds + '秒'); var time = hoursRound + ':' + minutesRound + ':' + seconds return time; }
