Question

我有一个JSfiddle，我试图在一个日期添加一周。当我尝试添加六天时，日期输出的日期不正确。

添加一周的代码

 var endDate =  new Date(date || Date.now()),
            eMonth = '' + (monthNames[endDate.getMonth()]),
            eDay = '' + (endDate.setDate(endDate.getDate() + 6)),
            eYear = endDate.getFullYear();

Answer 1

试试这个，

var endDate = new Date(date || Date.now());
var days = 6;
endDate.setDate(endDate.getDate() + days);

var eMonth = '' + (monthNames[endDate.getMonth()]),
    eDay = '' + endDate.getDate(),
    eYear = endDate.getFullYear();

Working Demo

Answer 2

eDay = '' + (endDate.getDate() + 6)

删除setDate()功能并更改$("#startDate").text(startDate)以在span标记中显示值

Answer 3

尝试一下，


var endDate =  new Date(date || Date.now());
endDate.setTime(startDateObj.getTime() + (1000 * 60 * 60 * 24 * 7));
var newDate = endDate.getFullYear()+"-"+(endDate.getMonth() + 1)+"-"+endDate.getDate();

Answer 4

您还可以使用get / set Time方法：

var today = new Date();
var plusOneWeek = new Date();
plusOneWeek.setTime( today.getTime()+(7*24*3600*1000) ); //add 7 days

请参阅MDN

上有关getTime()的文档

Answer 5

var now = new Date().getTime();
var oneWeek = 6*24*60*60*1000;
var newDate = now+oneWeek;
alert(new Date(newDate));

这应该做的工作
