当我将时钟设置为 29/04/2011 时，它会在周输入中增加36/4/2011！但正确的日期应该是6/5/2011
var d = new Date();
var curr_date = d.getDate();
var tomo_date = d.getDate()+1;
var seven_date = d.getDate()+7;
var curr_month = d.getMonth();
curr_month++;
var curr_year = d.getFullYear();
var tomorrowsDate =(tomo_date + "/" + curr_month + "/" + curr_year);
var weekDate =(seven_date + "/" + curr_month + "/" + curr_year);
{
jQuery("input[id*='tomorrow']").val(tomorrowsDate);
jQuery("input[id*='week']").val(weekDate);

Something like this?
像这样的东西？
var days = 7;
var date = new Date();
var res = date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
alert(res);
convert to date again:
再次转换为日期：
date = new Date(res);
alert(date)
or alternatively:
或者：
date = new Date(res);
// hours part from the timestamp
var hours = date.getHours();
// minutes part from the timestamp
var minutes = date.getMinutes();
// seconds part from the timestamp
var seconds = date.getSeconds();
// will display time in 10:30:23 format
var formattedTime = date + '-' + hours + ':' + minutes + ':' + seconds;
alert(formattedTime)

The simple way to get a date x days in the future is to increment the date:
获取未来 x 天日期的简单方法是增加日期：
function addDays(dateObj, numDays) {
return dateObj.setDate(dateObj.getDate() + numDays);
}
Note that this modifies the supplied date object, e.g.
请注意，这会修改提供的日期对象，例如
function addDays(dateObj, numDays) {
dateObj.setDate(dateObj.getDate() + numDays);
return dateObj;
}
var now = new Date();
var tomorrow = addDays(new Date(), 1);
var nextWeek = addDays(new Date(), 7);
alert(
'Today: ' + now +
'\nTomorrow: ' + tomorrow +
'\nNext week: ' + nextWeek
);

var days = 7;
var date = new Date();
var res = date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
var d = new Date(res);
var month = d.getMonth() + 1;
var day = d.getDate();
var output = d.getFullYear() + '/' +
(month < 10 ? '0' : '') + month + '/' +
(day < 10 ? '0' : '') + day;
$('#txtEndDate').val(output);

You can add or increase the day of week for the following example and hope this will helpful for you.Lets see....
您可以为以下示例添加或增加星期几，希望这对您有所帮助。让我们看看....

currentDate.setUTCHours(6);
//here 2 is day increament for the date and you can use -2 for decreament day
currentDate.setDate(currentDate.getDate() +parseInt(2));
//formatting date by mm/dd/yyyy
var dateInmmddyyyy = currentDate.getMonth() + 1 + '/' + currentDate.getDate() + '/' + currentDate.getFullYear();

var future = new Date(); // get today date
future.setDate(future.getDate() + 7); // add 7 days
var finalDate = future.getFullYear() +'-'+ ((future.getMonth() + 1) < 10 ? '0' : '') + (future.getMonth() + 1) +'-'+ future.getDate();
console.log(finalDate);回答by trickwallett
Using the Date object's methods willcould come in handy.
使用 Date 对象的方法 将要可以派上用场。
e.g.:
例如：
myDate = new Date();
plusSeven = new Date(myDate.setDate(myDate.getDate() + 7));

Two problems here:
这里有两个问题：
seven_dateis a number, not a date.29 + 7 = 36getMonthreturns a zero based index of the month. So adding one just gets you the current month number.
seven_date是一个数字，而不是日期。29 + 7 = 36getMonth返回该月的基于零的索引。所以添加一个只会让你得到当前的月份数。
