js如何将秒转化为时分秒

function formatSeconds(value) {
    var theTime = parseInt(value);// 秒
    var theTime1 = 0;// 分
    var theTime2 = 0;// 小时
    if (theTime > 60) {
        theTime1 = parseInt(theTime / 60);
        theTime = parseInt(theTime % 60);
        if (theTime1 > 60) {
            theTime2 = parseInt(theTime1 / 60);
            theTime1 = parseInt(theTime1 % 60);
        }
    }
    var result = "" + parseInt(theTime) + "秒";
    if (theTime1 > 0) {
        result = "" + parseInt(theTime1) + "分" + result;
    }
    if (theTime2 > 0) {
        result = "" + parseInt(theTime2) + "小时" + result;
    }
    console.log()
    return result;
}
formatSeconds(3800)
