获取当前日期时间并格式化

function getnowtime() {  
    var nowtime = new Date();  
    var year = nowtime.getFullYear();  
    var month = padleft0(nowtime.getMonth() + 1);  
    var day = padleft0(nowtime.getDate());  
    var hour = padleft0(nowtime.getHours());  
    var minute = padleft0(nowtime.getMinutes());  
    var second = padleft0(nowtime.getSeconds());  
    var millisecond = nowtime.getMilliseconds(); millisecond = millisecond.toString().length == 1 ? "00" + millisecond : millisecond.toString().length == 2 ? "0" + millisecond : millisecond;  
    return year + "-" + month + "-" + day + " " + hour + ":" + minute + ":" + second;  
}

function formatDate(time) {
    var now = null;
    if(time.toString().length == 10){
        now = new Date(time * 1000);
    }else{
        now = new Date(time);
    }
    var year = now.getFullYear();
    var month  = now.getMonth();
    var day = now.getDay();
    return year + '-' + month + '-' +day;
}
