JavaScript date objects UK dates
提问by Linda
I have the following code
我有以下代码
datePicker.change(function(){
dateSet = datePicker.val();
dateMinimum = dateChange();
dateSetD = new Date(dateSet);
dateMinimumD = new Date(dateMinimum);
if(dateSetD<dateMinimumD){
datePicker.val(dateMinimum);
alert('You can not amend down due dates');
}
})
dateSet = "01/07/2010" dateMinimum = "23/7/2010"
dateSet = "01/07/2010" dateMinimum = "23/7/2010"
Both are UK format. When the date objects are compared dateSetD should be less than dateMinimumD but it is not. I think it is to do with the facts I am using UK dates dd/mm/yyyy. What would I need to change to get this working?
两者都是英国格式。比较日期对象时，dateSetD 应该小于 dateMinimumD，但事实并非如此。我认为这与我使用英国日期 dd/mm/yyyy 的事实有关。我需要改变什么才能让它工作？

The JavaScript Dateconstructor doesn't parse strings in that form (whether in UK or U.S. format). See the specfor details, but you can construct the dates part by part:
JavaScriptDate构造函数不解析该格式的字符串（无论是英国格式还是美国格式）。有关详细信息，请参阅规范，但您可以部分构建日期：
new Date(year, month, day);
MomentJSmight be useful for dealing with dates flexibly. (This answer previously linked to this lib, but it's not been maintained in a long time.)

This is how I ended up doing it:
这就是我最终这样做的方式：
var lastRunDateString ='05/04/2012'; \5th april 2012
var lastRunDate = new Date(lastRunDateString.split('/')[2], lastRunDateString.split('/')[1] - 1, lastRunDateString.split('/')[0]);
Note the month indexing is from 0-11.
请注意，月份索引是从 0 到 11。

var dateString ='23/06/2015';
var splitDate = dateString.split('/');
var month = splitDate[1] - 1; //Javascript months are 0-11
var date = new Date(splitDate[2], month, splitDate[0]);

- Split the date into day, month, year parts using
dateSet.split('/') - Pass these parts in the right order to the Date constructor.
- 使用将日期拆分为日、月、年部分
dateSet.split('/') - 按正确的顺序将这些部分传递给Date 构造函数。

Yes, there is problem with the date format you are using. If you are not setting a date format the default date that is used is 'mm/dd/yy. So you should set your preferred date formate when you create it as following when you create the date picker:
是的，您使用的日期格式有问题。如果您没有设置日期格式，则使用的默认日期是'mm/dd/yy. 因此，在创建日期选择器时，您应该在创建时设置首选日期格式，如下所示：
$(".selector" ).datepicker({ dateFormat: 'dd/mm/yyyy' });
or you can set it later as:
或者您可以稍后将其设置为：
$.datepicker.formatDate('dd/mm/yyyy');

When you try to create a date object:
当您尝试创建日期对象时：
new Date(year, month, day, hours, minutes, seconds, milliseconds)
Example:
例子：
dateSetD = new Date(dateSet.year, dateSet.month, dateSet.day);
Note: JavaScript Date object's month starts with 00, so you need to adjust your dateset accordingly.
注意：JavaScript Date 对象的月份从 00 开始，因此您需要相应地调整您的日期集。
