【1】、毫秒数转换为具体日期

function getMyDate(str) {
    var oDate = new Date(str),
    oYear = oDate.getFullYear(),
    oMonth = oDate.getMonth()+1,
    oDay = oDate.getDate(),
    oHour = oDate.getHours(),
    oMin = oDate.getMinutes(),
    oSen = oDate.getSeconds(),
    oTime = oYear +'-'+ addZero(oMonth) +'-'+ addZero(oDay) +' '+ addZero(oHour) +':'+
addZero(oMin) +':'+addZero(oSen);
    return oTime;
}

//补零操作
function addZero(num){
    if(parseInt(num) < 10){
        num = '0'+num;
    }
    return num;
}

接口返回的毫秒数如果为string,需要转化为int

var dateTime = getMyDate(parseInt(data));


 data:  1537444800000
 dateTime:2018-09-20 20:00:00


【2】、日期转换为毫秒数

var secondsTime = new Date(dateTime).getTime();


 dateTime:2018-09-20 20:00:00

secondsTime:  1537444800000

Date.prototype.Format = function (fmt) {

};
if (/(y+)/.test(fmt))
fmt=fmt.replace(RegExp.$1, ( this .getFullYear()+ "" ).substr(4 - RegExp.$1.length));
for ( var k in o)
if ( new RegExp( "(" + k + ")" ).test(fmt))
fmt = fmt.replace(RegExp.$1, (RegExp.$1.length==1) ? (o[k]) : (( "00" + o[k]).substr(( "" + o[k]).length)));
return fmt;
}
 
var today = new Date();
$( '#bdate' ).val(today.Format( "yyyy-MM-dd" ));
$( '#edate' ).val(today.Format( "yyyy-MM-dd" ));

从后台获取的为毫秒数,

首先,将毫秒数转换为Date对象

 

第二,将Date对象转换成字符串。也可以使用toLocalString()方法,但是格式难以自定义

function dateForm(time){
                 var unixTimestamp = new Date( 1477386005*1000 );
                 commonTime = unixTimestamp.toLocaleString();
             }
             Date.prototype.toLocaleString = function () {
                 return this .getFullYear() + "/" + ( this .getMonth() + 1) + "/" + this .getDate() + "/" + this .getHours() + ":" + this .getMinutes() + ":" + this .getSeconds();
             };

  new Data(‘毫秒数’)是标准时间,

  new Data().getTime()是把标准时间转换成毫秒数
