关于new Date()的日期格式处理

var myDate = new Date();

myDate.getYear(); //获取当前年份(2位)

myDate.getFullYear(); //获取完整的年份(4位,1970-????)

myDate.getMonth(); //获取当前月份(0-11,0代表1月)         // 所以获取当前月份是myDate.getMonth()+1;

myDate.getDate(); //获取当前日(1-31)

myDate.getDay(); //获取当前星期X(0-6,0代表星期天)

myDate.getTime(); //获取当前时间(从1970.1.1开始的毫秒数)

myDate.getHours(); //获取当前小时数(0-23)

myDate.getMinutes(); //获取当前分钟数(0-59)

myDate.getSeconds(); //获取当前秒数(0-59)

myDate.getMilliseconds(); //获取当前毫秒数(0-999)

myDate.toLocaleDateString(); //获取当前日期

var mytime=myDate.toLocaleTimeString(); //获取当前时间

myDate.toLocaleString( ); //获取日期与时间  

var date= new Date(Date.parse(strTime.replace(/-/g,  "/")));//转换成Data();

var formatDate = function (date) {

    var y = date.getFullYear();

    var m = date.getMonth() + 1;

    m = m < 10 ? '0' + m : m;

    var d = date.getDate();

    d = d < 10 ? ('0' + d) : d;

    return y + '-' + m + '-' + d;

};  

arr.date = new Date();

      var d = new Date(arr.date);

      var yue = (d.getMonth() + 1) > 9 ? (d.getMonth() + 1) : '0' + (d.getMonth() + 1);

      var re = d.getDate() > 9 ? d.getDate() : '0' + d.getDate();

      var youWant = d.getFullYear() + '-' + yue + '-' + re;

      arr.date = youWant;

//时间戳转日期格式

      var formatDateTime3 = function(time, format){

          var t = new Date(time);

          var tf = function(i){return (i < 10 ? '0' : '') + i};

          return format.replace(/yyyy|MM|dd|HH|mm|ss/g, function(a){

              switch(a){

                  case 'yyyy':

                      return tf(t.getFullYear());

                      break;

                  case 'MM':

                      return tf(t.getMonth() + 1);

                      break;

                  case 'mm':

                      return tf(t.getMinutes());

                      break;

                  case 'dd':

                      return tf(t.getDate());

                      break;

                  case 'HH':

                      return tf(t.getHours());

                      break;

                  case 'ss':

                      return tf(t.getSeconds());

                      break;

              }

          })

      }; 

var time1=‘2016-01-01 17:22:37’；

var date=new Date(time1.replace(/-/g, '/'));  //开始时间

var time2=date.getTime();
