【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

截图如下
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
