js timestamp 转换 date 和 将秒数整理为时分秒格式

// 获得的后台json 时间格式转化 例如：1520305366000  转化为XXXX-XX-XX类似这种

function timeStamp2String(time){
var datetime = new Date();
datetime.setTime(time);
var year = datetime.getFullYear();
var month = datetime.getMonth() + 1 < 10 ? "0" + (datetime.getMonth() + 1) : datetime.getMonth() + 1;
var date = datetime.getDate() < 10 ? "0" + datetime.getDate() : datetime.getDate();
var hour = datetime.getHours()< 10 ? "0" + datetime.getHours() : datetime.getHours();
var minute = datetime.getMinutes()< 10 ? "0" + datetime.getMinutes() : datetime.getMinutes();
var second = datetime.getSeconds()< 10 ? "0" + datetime.getSeconds() : datetime.getSeconds();
return year + "-" + month + "-" + date+“-”+hours+“-”+minutes+“-”+seconds;
}

//js转化获取的秒数 ， 为06:23，用于时钟、音视频播放。

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 (10 > theTime > 0) {
result = "0" + parseInt(theTime);//秒
} else {
result = "" + parseInt(theTime);//秒
}

if (10 > theTime1 > 0) {
result = "0" + parseInt(theTime1) + ":" + result;//分，不足两位数，首位补充0，
} else {
result = "" + parseInt(theTime1) + ":" + result;//分
}
if (theTime2 > 0) {
result = "" + parseInt(theTime2) + ":" + result;//时
}
return result;

}
