JavaScript秒到时间字符串,格式为hh:mm:ss

javascript

我想将持续时间(即秒数)转换为以冒号分隔的时间字符串(hh:mm:ss)

我在这里找到了一些有用的答案,但他们都谈论转换为x小时和x分钟格式。

那么,有没有一个小片段在jQuery或原始JavaScript中做到这一点?

String.prototype.toHHMMSS = function () {
    var sec_num = parseInt(this, 10); // don't forget the second param
    var hours   = Math.floor(sec_num / 3600);
    var minutes = Math.floor((sec_num - (hours * 3600)) / 60);
    var seconds = sec_num - (hours * 3600) - (minutes * 60);

    if (hours   < 10) {hours   = "0"+hours;}
    if (minutes < 10) {minutes = "0"+minutes;}
    if (seconds < 10) {seconds = "0"+seconds;}
    return hours+':'+minutes+':'+seconds;
}

您现在可以像这样使用它:

alert("5678".toHHMMSS());

工作片段:

String.prototype.toHHMMSS = function () {

    var sec_num = parseInt(this, 10); // don't forget the second param

    var hours   = Math.floor(sec_num / 3600);

    var minutes = Math.floor((sec_num - (hours * 3600)) / 60);

    var seconds = sec_num - (hours * 3600) - (minutes * 60);



    if (hours   < 10) {hours   = "0"+hours;}

    if (minutes < 10) {minutes = "0"+minutes;}

    if (seconds < 10) {seconds = "0"+seconds;}

    return hours + ':' + minutes + ':' + seconds;

}



console.log("5678".toHHMMSS());
