js获取格式化后的当前时间

代码如下：

function getFormatDate() {
    var day=new Date();
    var Year=0;
    var Month=0;
    var Day=0;
    var Hour = 0;
    var Minute = 0;
    var Second = 0;
    var CurrentDate="";
    //初始化时间
    Year = day.getFullYear();
    Month = day.getMonth()+1;
    Day = day.getDate();
    Hour = day.getHours();
    Minute = day.getMinutes();
    Second = day.getSeconds();
    CurrentDate = CurrentDate + Year + "-";
    if (Month >= 10 ){
        CurrentDate = CurrentDate + Month + "-";
    }else{
        CurrentDate = CurrentDate + "0" + Month + "-";
    }
    if (Day >= 10 ){
        CurrentDate = CurrentDate + Day
    }else{
        CurrentDate = CurrentDate + "0" + Day
    }
    if(Hour >=10){
        CurrentDate += "  "+Hour
    }else{
        CurrentDate += "  0" + Hour
    }
    if(Minute >=10){
        CurrentDate = CurrentDate + ":" + Minute
    }else{
        CurrentDate = CurrentDate + ":0" + Minute
    }
    if(Second>=10){
        CurrentDate = CurrentDate + ":" + Second;
    }else{
        CurrentDate = CurrentDate + ":0" + Second;
    }
    return CurrentDate;
}
