js日期格式化

//js日期格式化(yyyy-mm-dd HH:MM:SS)

一、
//获取当前时间
function getNowTime() {

　　var time = new Date();
      var month = "";//月
      if(time.getMonth()<9){
          month = "0"+(time.getMonth()+1);
      }else{
          month += (time.getMonth()+1);
      }
      var date = "";//日
      if(time.getDate()<9){
          date = "0"+time.getDate();
      }else{
          date += time.getDate();
      }
      var hours = "";//时
      if(time.getHours()<10){
          hours = "0"+time.getHours();
      }else{
          hours += time.getHours();
      }
      var minutes = "";//分
      if(time.getMinutes()<10){
          minutes = "0"+time.getMinutes();
      }else{
          minutes += time.getMinutes();
　　}
      var seconds = "";//秒
      if(time.getSeconds()<10){
          seconds = "0"+time.getSeconds();
　　}else{
          seconds += time.getSeconds();
   }
   var nowTime =  time.getFullYear() + "/" + month + "/" + date +" "+ hours + ":" + minutes + ":" + seconds;
　　return nowTime;
}

二、
//将时间转换成(yyyy-mm-dd HH:MM:SS)格式的字符串
function getLocalTime(nS) {  
    var date = new Date(nS);
    var year = date.getFullYear();
    var month = date.getMonth()+1;
    var day = date.getDate();
    var hours= date.getHours(); //获取系统时，
    var minutes=  date.getMinutes(); //分
    var second=  date.getSeconds(); //秒
    if(second==0){
       second=second+"0";
    }
    return year+"-"+month+"-"+day+" "+hours+":"+minutes+":"+second;
}
