请帮助日期 [英] Please Help with Dates
问题描述
此问题似乎取决于计算机系统设置。
当系统日期设置为M / d / yyyy但我确实没有问题
将系统日期设置为d / M / yyyy时出现问题。
我在网页上有一个文本框，其中包含日期ie）
document.frmTimesheet.tWeekFrom.value = 19/12/2004
theDate = new Date（document.frmTimesheet.tWeekFrom.value）;
//拆分为日，月，年
iDay = theDate.getDate（）;
iMonth = theDate.getMonth（）+ 1;
iYear = theDate.getFullYear（）;
alert（iDay）;
alert（iMonth）;
alert（ iYear）;
iday = 12
iMonth = 07
iYear = 2005
如果有任何方法可以做到这一点，我们将非常感谢任何帮助。
This problem seems to occur dependant on the computer system settings.
I have no issues when the system date is set as M/d/yyyy but I do
have a problem with the system date set as d/M/yyyy.
I have a text box on a web page that holds the date ie)
document.frmTimesheet.tWeekFrom.value = 19/12/2004
theDate = new Date(document.frmTimesheet.tWeekFrom.value);
// split into day, month, year
iDay = theDate.getDate();
iMonth = theDate.getMonth()+1;
iYear = theDate.getFullYear();
alert(iDay);
alert(iMonth);
alert(iYear);
iday= 12
iMonth= 07
iYear= 2005
If there is any way to do this any help would be greatly appreciated.

没有具体的定义来指定字符串应该如何
解析。这完全取决于实施。这可能意味着解析
将取决于区域设置，或者它可能固定为某种格式的
格式。
在我看来，自己解析字符串并使用
其他形式的Date构造函数更安全：
var date = new日期（年，月，日，小时，分钟，秒，毫秒）;
虽然在你的情况下，你只需要担心前三个
参数。
当然，另一个问题是你接受的格式。
最好避免dd / mm / yyyy和mm / dd / yyyy，除非你只吸引那些使用其中一个的观众。

替换.invalid与.uk通过电子邮件回复。
There is no concrete definition that specifies how a string should be
parsed. It''s entirely up to the implementation. That may mean that parsing
would depend on the locale settings, or it may be fixed to a certain set
of formats.
In my opinion, it''s far safer to parse the string yourself and use the
other form of Date constructor:
var date = new Date(year, month, day, hr, min, sec, ms);
though in your case, you only need to worry about the first three
arguments.
Of course, the other concern is what formats you accept. It''s best to
avoid dd/mm/yyyy and mm/dd/yyyy unless you''ll only attract audiences that
uses one of those.

有没有办法确定用户如何进行计算机设置
配置？
我正在考虑使用验证，但如果月份有效，它仍将是
是错的
例如。）06/10/2004将是一个有效的日期但是如果设置了d / m / y它将解析
与Windows中的m / d / y不同
认为它是2004年10月10日而不是Jun e 10/2004
和13/06/2004是2005年6月1日将月份从13改为1并逐年推进
br />
日历控件正在加载文本框并使用系统日期
包括格式。
如果我不知道如何系统正在查看这个，我该如何解析它
正确。
如果系统日期格式= d / m / yy那么
d =" 13/12 / 2004 ''这将是过去的日期
a = d.split（" /"）
theDate = new Date（a [2]，a [1] - 1，a [0]）;
Else
d =" 12/13/2004" ''这将是过去的日期
theDate = new Date（d）;

Is there a way to determine how the user has their computer settings
configured?
I was thinking of using a verify but if the month is valid it will still
be wrong
eg.) 06/10/2004 will be a valid date but if d/m/y is set it will parse
differently vs. m/d/y in Windows
Thinks it is Oct 10/2004 instead of June 10/2004
and 13/06/2004 is 01/06/2005 moving the month from 13 to 1 and advancing
the year by one
A calendar control is loading the text boxes and uses the system date
including the format.
If I do not know how the system is looking at this, how can I parse it
correctly.
If system date format = d/m/yy then
d = "13/12/2004" ''This would be the passed date
a = d.split("/")
theDate = new Date(a[2],a[1]-1,a[0]);
Else
d = "12/13/2004" ''This would be the passed date
theDate = new Date(d);
end if
