问题描述

我试图使用javascript添加几天给定的日期。我有以下代码

I am trying to add days to a given date using javascript. I have the following code

function onChange(e) {
    var datepicker = $("#DatePicker").val();
    alert(datepicker);
    var joindate = new Date(datepicker);
    alert(joindate);
    var numberOfDaysToAdd = 1;
    joindate.setDate(joindate + numberOfDaysToAdd);
    var dd = joindate.getDate();
    var mm = joindate.getMonth() + 1;
    var y = joindate.getFullYear();
    var joinFormattedDate = dd + '/' + mm + '/' + y;
    $('.new').val(joinFormattedDate);
}

在第一次提醒时,我收到日期 24/06 / 2011 但是在第二个警报我得到 Thu Dec 06 2012 00:00:00 GMT + 0500(巴基斯坦标准时间)这是我想要的错它保持 24/06/2011 ,以便我可以添加几天。在我的代码中,我希望我的最终输出是 25/06/2011

On first alert i get the date 24/06/2011 but on second alert i get Thu Dec 06 2012 00:00:00 GMT+0500 (Pakistan Standard Time) which is wrong i want it to remain 24/06/2011 so that i can add days to it. In my code i want my final output to be 25/06/2011

推荐答案

Date('string')将尝试解析字符串为 m / d / yyyy 。因此,字符串 24/06/2011 因此变为 2012年12月6日。原因:24被视为一个月... 1 => 2011年1月,13 => 2012年1月,因此24 => 2012年12月。希望你明白我的意思。所以:

Date('string') will attempt to parse the string as m/d/yyyy. The string 24/06/2011 thus becomes Dec 6, 2012. Reason: 24 is treated as a month... 1 => January 2011, 13 => January 2012 hence 24 => December 2012. I hope you understand what I mean. So:

var dmy = "24/06/2011".split("/");        // "24/06/2011" should be pulled from $("#DatePicker").val() instead
var joindate = new Date(
    parseInt(dmy[2], 10),
    parseInt(dmy[1], 10) - 1,
    parseInt(dmy[0], 10)
);
alert(joindate);                          // Fri Jun 24 2011 00:00:00 GMT+0500 (West Asia Standard Time) 
joindate.setDate(joindate.getDate() + 1); // substitute 1 with actual number of days to add
alert(joindate);                          // Sat Jun 25 2011 00:00:00 GMT+0500 (West Asia Standard Time)
alert(
    ("0" + joindate.getDate()).slice(-2) + "/" +
    ("0" + (joindate.getMonth() + 1)).slice(-2) + "/" +
    joindate.getFullYear()
);
