Javascript日期和他们的操纵 [英] Javascript dates and their manipulation
问题描述
我写了几个有while的脚本。如果日期与一组日期中的一个日期不匹配，则会将
日期增加一天。
但是，有时它显然会逐步退出while循环虽然我的病情没有得到满足，但是
。会工作几个循环然后逐步走出
经常。
是否有javascript" date"问题是什么？我还注意到Firefox和Internet Explorer之间的结果不同。
感谢任何评论，
pj 。 。 。
I''ve written several scripts that have "while" blocks which increment a
date by one day if the date does not match one of a group of dates.
However, sometimes it apparently steps out out the while loop even
though my condition isn''t met. Will work for a few loops then steps out
often.
Are there javascript "date" issues? I have also noticed different
results between Firefox and Internet Explorer.
thanks for any comments,
pj . . .

actually does, and that is most apparent when the code is present,
or better still, linked to at an example URL.

''javascript''日期问题？可能，最近有一位日期大师'
在这里，正在思考他在JS日期函数中获得的差异，因为它在各种UA中运行是的。
应该注意的是，这是一个神秘且不寻常的b $ b b情形，而99（.9）％的有趣小''日期''
问题不是由于该工具的
部分（在本例中为JS）中的神秘失败造成的，而是基本的
理解一件非常复杂的事情（日期）。
为了更好地理解日期的整个问题，
你可以检查一下网站链接JS常见问题..

''javascript'' date issues? Possibly, one of the date guru''s
was here recently, musing over the differences he was getting
on a JS date function as operated across a variety of UA''s.
It should be noted that it was an arcane and unusual
situation though, and that 99(.9)% of funny little ''date''
issues are caused not so much by arcane failings on the
part of the tool (JS, in this instance), so much as a basic
understanding of a very complex thing (dates).
For a better understanding of the entire matter of dates,
you might check the site linked from the JS FAQ..

I''m sure that could be phrased far more simply. :)

没有那么多不寻常，但没有说明。 ECMAScript标准没有b $ b指定实现应该接受的日期格式，
以及与字符串相关的格式应该生成什么格式。唯一的
规定是
d.valueOf（）= Date.parse（d.toString（））= Date.parse（d.toUTCString（ ））
也就是说，实现产生的任何字符串也应该是可解析的。
假设某些标准是合理的格式应该正确解释为
，例如yyyy-mm-dd hh：mm：ss，但它不是由常识以外的其他任何东西保证的。

替换.invalid与.uk通过电子邮件回复。
Not so much unusual, but unspecified. The ECMAScript Standard doesn''t
specify anything about the date formats an implementation should accept,
nor what format string-related methods should produce. The only
stipulation is that
d.valueOf() = Date.parse(d.toString()) = Date.parse(d.toUTCString())
That is, any string produced by an implementation should also be parsable.
It''s reasonable to assume that certain standard formats should be
correctly interpreted, such as yyyy-mm-dd hh:mm:ss, but it''s not
guaranteed by anything other than common sense.
