javascript日期转换 时间戳转日期格式

复制代码 代码如下:

  Date.prototype.format = function(format)

  {

  var o =

  {

  "M+" : this.getMonth()+1, //month

  "d+" : this.getDate(), //day

  "h+" : this.getHours(), //hour

  "m+" : this.getMinutes(), //minute

  "s+" : this.getSeconds(), //second

  "q+" : Math.floor((this.getMonth()+3)/3), //quarter

  "S" : this.getMilliseconds() //millisecond

  }

  if(/(y+)/.test(format))

  {

  format = format.replace(RegExp.$1, (this.getFullYear()+"").substr(4 - RegExp.$1.length));

  }

  for(var k in o)

  {

  if(new RegExp("("+ k +")").test(format))

  {

  format = format.replace(RegExp.$1, RegExp.$1.length==1 ? o[k] : ("00"+ o[k]).substr((""+ o[k]).length));

  }

  }

  return format;

  }

  var testDate = new Date( 1320336000000 );//这里必须是整数,毫秒

  var testStr = testDate.format("yyyy年MM月dd日hh小时mm分ss秒");

  var testStr2 = testDate.format("yyyyMMdd hh:mm:ss");

  alert(testStr + " " + testStr2);
