Question

我需要从当前日期找出上一年的日期，然后在javascript中的jQuery UIdatepicker中设置为minDate

我的日期格式为dd-mm-yy

即

当前日期为25-07-2012
我需要25-07-2011

Answer 1

您需要使用getFullYear()

然后生成新日期

var d = new Date(2012, 7, 25);
d.setFullYear(d.getFullYear() - 1);

Answer 2

试试这个

var d = new Date();
var pastYear = d.getFullYear() - 1;
d.setFullYear(pastYear);
console.log(d);

Answer 3

使用此：

 var date = new Date();
 var intYear = date.getFullYear() - 1;

Answer 4

Datepicker允许您将数字作为minDate选项，并将其用作当前日期的偏移量。所以你可以写：

minDate: -365

指定1年前。不过，这并没有考虑到闰年。

Answer 5

对于字符串：

curdate.substr(0, 6)+(curdate.substr(6)-1);

如果您使用Date object，则可以使用set[Full]Year方法轻松减去一年。

Answer 6

我在Angular 7中遇到了同样的问题。以下是我在打字稿中的解决方案。

new Date(new Date().setFullYear(new Date().getFullYear() - 1))

Answer 7

此解决方案会有所帮助。

new Date(new Date().setFullYear(new Date().getFullYear() - 1));

Answer 8

避免使用Date对象（如果这是OP所希望的）：

var currDate = '25-07-2012';
var dateParts = currDate.split('-');
dateParts[2] = parseInt(dateParts[2], 10) - 1;
alert(dateParts.join('-'));

Answer 9

var today = new Date();
var curyear = today.getFullYear();
var curyearMonth = today.getMonth() + 1;
var curyearDay = today.getDate();
var lastYear = curyear - 1;
if ((curyearMonth == 2) && (curyearDay == 29)) {
    curyearDay = 28;
}

var lastYearDisplay = ("0000" + lastYear.toString()).slice(-4) + "-" + ("00" + curyearMonth.toString()).slice(-2) + "-" + ("00" + curyearDay.toString()).slice(-2);
alert("LastWeekDate : " + lastYearDisplay);

Answer 10

您可以将新日期或现有日期定义为d变量

var d = new Date();

然后您可以使用${variableName}将日期，月份和年份放入新的日期字符串中，另外，您必须在d.getMonth（）中添加1，然后从d.getFullYear（）中减去1。

var previousYearDate = `${d.getDate()}-${d.getMonth() + 1}-${d.getFullYear() - 1}`;

Answer 11

var date = CALC.today(); //(function in my dev-enviro - gives today's date)
var year = formatDate(date, 'yyyy'); //year is 2016
year = parseInt(year);               //make sure '2016' becomes an integer
year = year -1;                      // var year is now: 2015.

//its been a while, but that's what I did from memory.

Answer 12

  function getTodayDate() {
        var today = new Date();
        var dd = today.getDate();
        var mm = today.getMonth() + 1; //January is not 0!
        var yyyy = today.getFullYear();
        if (dd < 10) { dd = '0' + dd }
        if (mm < 10) { mm = '0' + mm }
        today = yyyy + '-' + mm + '-' + dd;
        return today;
    };
    function getYearAgo(){
    var lastYear = new Date();
    var dd = lastYear.getDate();
    var mm = lastYear.getMonth() + 1; //January is not 0!
    var yyyy = lastYear.getFullYear(getTodayDate) - 1;
    if (dd < 10) { dd = '0' + dd }
    if (mm < 10) { mm = '0' + mm }
    lastYear = yyyy + '-' + mm + '-' + dd;     
    return lastYear;
    }
