Jquery datepicker returns NAN as timestamp
提问by sunny_side_of_life
I am using jquery datepickerto select a date and convert to timestamp (epoch time). The script works arbitrarily. It shows timestamp for dates from 1st to 12th of any chosen month but makes time 12:00am of those days (I converted it online). But from 13th to the end of the month it shows NANas timestamp. Strange enough when the date formated to dd/mm/yy all the days shows correctly.
我正在使用jquery datepicker选择一个日期并转换为时间戳（纪元时间）。该脚本可以任意工作。它显示任何选定月份的 1 日至 12 日的时间戳，但将时间设为这些天的凌晨 12:00（我将其在线转换）。但是从 13 号到月底它显示NAN作为时间戳。当日期格式为 dd/mm/yy 所有天都正确显示时，这很奇怪。
$(function() {
$("#datepicker").datepicker({dateFormat: 'dd-mm-yy',
onSelect: function(dateText, inst) {
var dtV = $(this).val();
var d = new Date(dtV);
var s = parseInt((d)/1000);
$("#selectedDate").text("on " + dateText + "");
$(".selectedDate2").text(s.valueOf());
}
});
});

When you call new Date()you have to pass a valid date. dd-mm-yyis not a valid date for Dateand it's chenging your month per day.
当你打电话时，new Date()你必须通过一个有效的日期。dd-mm-yy不是一个有效的日期Date，它每天都在改变你的月份。
If you cannot change your date format, try this:
如果您无法更改日期格式，请尝试以下操作：
onSelect: function(dateText, inst) {
var dtV = $(this).val();
var exploded=dtV.split("-");
var d = new Date(exploded[2],exploded[1],exploded[0]);
EDIT: Better and shorter, use datepicker's getDateto get a Dateobject:
编辑：更好更短，使用日期选择器getDate来获取Date对象：
onSelect: function(dateText, inst) {
var d = $(this).datepicker("getDate");

I had a similar problem: usually the datepicker worked properly, also for dates with the day after the 12th; but from time to time I saw in Google Analytics that a user was getting NaN-NaN-NaN.
我有一个类似的问题：通常日期选择器工作正常，也适用于 12 日之后的日期；但有时我在谷歌分析中看到用户得到NaN-NaN-NaN。
After investigating, I discovered that it could be due to Google Translate.
经过调查，我发现这可能是由于谷歌翻译。
I checked in my analytics the language of the users getting the error. Almost all of them had a language that my website did not support. That was enough to assume that Google Translator was causing the error.
我在我的分析中检查了收到错误的用户的语言。几乎所有人都有我的网站不支持的语言。这足以假设是谷歌翻译导致了错误。
To solve it, as explained here, add the class:
要解决它，如解释here，添加类：
$(function() {
$(".datepicker").datepicker();
$('.ui-datepicker').addClass('');
});

It's interpreting your format as if it's mm-dd-yy; JavaScript's native Dateclass assumes all string input in the format \d\d[-/]\d\d[-/]\d\dis mm-dd-yy.
它正在解释您的格式，好像它是mm-dd-yy; JavaScript 的本机Date类假定格式\d\d[-/]\d\d[-/]\d\d为mm-dd-yy.
The yyyy-mm-ddformat ISO 8601is more common and should be interpreted correctly.
该yyyy-mm-dd格式ISO 8601是比较常见的，应予以正确解释。

Following works for me. Just added a ui-datepickerclass:
以下对我有用。刚刚添加了一个ui-datepicker类：
$(function () {
$("#txtStartDate").datepicker();
$('.ui-datepicker').addClass('');
});
