javascript - 如何在 JavaScript 中运行 0 到 10 分钟的计时器？

Question

您能告诉我如何在 JavaScript 中运行 0 到 10 分钟的计时器吗？

这是我的代码:

var secondsToMinutesAndSeconds = function (time) {
        // Minutes and seconds
        var mins = ~~(time / 60);
        var secs = time % 60;

        // Hours, minutes and seconds
        var hrs = ~~(time / 3600);
        var mins = ~~((time % 3600) / 60);
        var secs = time % 60;

        var ret = ""; //OUPUT: HH:MM:SS or MM:SS
        if (hrs > 0) {
            ret += "" + hrs + ":" + (mins < 10 ? "0" : "");
        }

        ret += "" + mins + ":" + (secs < 10 ? "0" : "");
        ret += "" + secs;
        return ret;
    };
// time given by server 
var uitat = 600;
var jobSessionTime ;

function callAtInterval() {
            if (parseInt(uitat) > 0) {
               uitat = parseInt(uitat) - 1;
                jobSessionTime = secondsToMinutesAndSeconds(uitat);
              console.log(jobSessionTime)
            } else {
              console.log('=====')

            }
        }
// time given by server 600
       jobSessionTime = secondsToMinutesAndSeconds(600);
     var stop = setInterval(callAtInterval, 1000);

目前打印时间为 10:00 到 00:00我希望它从 00:00 打印到 10:00。

var secondsToMinutesAndSeconds = function (time) {
        // Minutes and seconds
        var mins = ~~(time / 60);
        var secs = time % 60;

        // Hours, minutes and seconds
        var hrs = ~~(time / 3600);
        var mins = ~~((time % 3600) / 60);
        var secs = time % 60;

        var ret = ""; //OUPUT: HH:MM:SS or MM:SS
        if (hrs > 0) {
            ret += "" + hrs + ":" + (mins < 10 ? "0" : "");
        }

        ret += "" + mins + ":" + (secs < 10 ? "0" : "");
        ret += "" + secs;
        return ret;
    };
// time given by server 
var uitat = 0;
var jobSessionTime ;

function callAtInterval() {
            if (parseInt(uitat) < 600) {
               uitat = parseInt(uitat) + 1;
                jobSessionTime = secondsToMinutesAndSeconds(uitat);
              console.log(jobSessionTime)
            } else {
              clearInterval(stop);

            }
        }
// time given by server 600
       jobSessionTime = secondsToMinutesAndSeconds(0);
     var stop = setInterval(callAtInterval, 1000);
