本文主要为大家分享一篇JS计算距当前时间的时间差实例，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧，希望能帮助到大家。
如下所示：
/**
* JS获取距当前时间差
*
* @param int time 时间戳格式
*
*/
function get_time_diff(time) {
var diff = '';
var time_diff = new Date().getTime() - time; //时间差的毫秒数
//计算出相差天数
var days = Math.floor(time_diff / (24 * 3600 * 1000));
if (days > 0) {
diff += days + '天';
}
//计算出小时数
var leave1 = time_diff % ( 24 * 3600 * 1000);
var hours = Math.floor(leave1 / (3600 * 1000));
if (hours > 0) {
diff += hours + '小时';
} else {
if (diff !== '') {
diff += hours + '小时';
}
}
//计算相差分钟数
var leave2 =leave1 % (3600 * 1000);
var minutes = Math.floor(leave2 / (60 * 1000));
if (minutes > 0) {
diff += minutes + '分';
} else {
if (diff !== '') {
diff += minutes + '分';
}
}
//计算相差秒数
var leave3 = leave2%(60*1000);
var seconds = Math.round(leave3/1000);
if (seconds > 0) {
diff += seconds + '秒';
} else {
if (diff !== '') {
diff += seconds + '秒';
}
}
return diff;
