js中格式化时间戳

//将时间戳格式化
function getMyDate(time){  //time为时间戳
    if(typeof(time)=="undefined"){
        return "";
    }
    var oDate = new Date(time),
     oYear = oDate.getFullYear(),
     oMonth = oDate.getMonth()+1,
     oDay = oDate.getDate(),
     oHour = oDate.getHours(),
     oMin = oDate.getMinutes(),
     oSen = oDate.getSeconds(),
     oTime = oYear +‘-‘+ getzf(oMonth) +‘-‘+ getzf(oDay) +‘ ‘+ getzf(oHour) +‘:‘+ getzf(oMin) +‘:‘+getzf(oSen);//最后拼接时间  

     return oTime;
    };

     //补0操作,当时间数据小于10的时候，给该数据前面加一个0
    function getzf(num){
        if(parseInt(num) < 10){
            num = ‘0‘+num;
        }
        return num;
    }
