旅游日期无效 [英] Invalid date in safari
问题描述
alert(new Date('2010-11-29'));
chrome，ff没有这个问题，但safari会发出无效的日期。为什么？
chrome, ff doesn't have problems with this, but safari cries "invalid date". Why ?
编辑：好的，根据下面的评论，我使用字符串解析，并尝试这样：
edit : ok, as per the comments below, I used string parsing and tried this :
alert(new Date('11-29-2010')); //doesn't work in safari
alert(new Date('29-11-2010')); //doesn't work in safari
alert(new Date('2010-29-11')); //doesn't work in safari
推荐答案
code> yyyy-MM-dd 不是 Date 构造函数的正式支持格式。 Firefox似乎支持它，但不要依赖于其他浏览器执行相同操作。
The pattern yyyy-MM-dd isn't an officially supported format for Date constructor. Firefox seems to support it, but don't count on other browsers doing the same.
以下是一些支持的字符串，取自这个网站：
Here are some of supported strings, taken from this site:
- MM-dd-yyyy
- yyyy / MM / dd
- MM / dd / yyyy
- MMMM dd，yyyy
- MMM dd，yyyy
- MM-dd-yyyy
- yyyy/MM/dd
- MM/dd/yyyy
- MMMM dd, yyyy
- MMM dd, yyyy
DateJS 似乎是解析非标准日期格式的好库。
DateJS seems like a good library for parsing non standard date formats.
编辑：只是检查 ECMA-262标准。来自第15.9.1.15节：
Edit: just checked ECMA-262 standard. Quoting from section 15.9.1.15:
日期时间字符串格式
ECMAScript定义基于简化ISO
8601扩展格式的日期时间
的字符串
交换格式。格式为
，如下所示：YYYY-MM-DDTHH：mm：ss.sssZ
其中的字段如下：
ECMAScript defines a string interchange format for date-times based upon a simplification of the ISO 8601 Extended Format. The format is as follows: YYYY-MM-DDTHH:mm:ss.sssZ Where the fields are as follows:
- YYYY是公历中年份的十进制数字。
- ：（hyphon）在字符串中直接显示两次。
- MM是从01（1月）到12（12月）的一年中的月份。
- DD是01到31月的日期。
- TT字面上出现在字符串中，表示
时间元素。 - HH是自午夜以来的两个
十进制数字的完成小时数。 - ：：（冒号）字符串中两次出现。
- mm是从小时开始的完成分钟数，
为两位十进制数字。 - ss是从分钟开始的完整秒数
作为两位十进制数字。 - 。 。 （点）字面上出现在字符串中。
- sss是从
秒开始以三位十进制数后的完整毫秒数。两个
的。并且可以省略毫秒字段
。 - Z是指定为Z（UTC）或+或 -
的时区偏移量，后跟时间表达式hh：mm
- YYYY is the decimal digits of the year in the Gregorian calendar.
- ":" (hyphon) appears literally twice in the string.
- MM is the month of the year from 01 (January) to 12 (December).
- DD is the day of the month from 01 to 31.
- T "T" appears literally in the string, to indicate the beginning of the time element.
- HH is the number of complete hours that have passed since midnight as two decimal digits.
- : ":" (colon) appears literally twice in the string.
- mm is the number of complete minutes since the start of the hour as two decimal digits.
- ss is the number of complete seconds since the start of the minute as two decimal digits.
- . "." (dot) appears literally in the string.
- sss is the number of complete milliseconds since the start of the second as three decimal digits. Both the "." and the milliseconds field may be omitted.
- Z is the time zone offset specified as "Z" (for UTC) or either "+" or "-" followed by a time expression hh:mm
此格式包括日期格式：
- YYYY
- YYYY-MM
- YYYY-MM-DD
它还包括带有
的仅限时间表格，附加可选的时区偏移量：
It also includes time-only forms with an optional time zone offset appended:
- THH：mm
-
- THH：mm：ss
- THH：mm：ss.sss
还包括日期时间，其中
可以是上述的任何组合。
Also included are "date-times" which may be any combination of the above.
所以，似乎YYYY-MM-DD被包含在标准中，但由于某些原因，Safari不支持它。
So, it seems that YYYY-MM-DD is included in the standard, but for some reason, Safari doesn't support it.
更新 ：在查看 datejs文档后，使用它，您的问题应该解决使用代码喜e：
Update: after looking at datejs documentation, using it, your problem should be solved using code like this:
var myDate1 = Date.parseExact("29-11-2010", "dd-MM-yyyy");
var myDate2 = Date.parseExact("11-29-2010", "MM-dd-yyyy");
var myDate3 = Date.parseExact("2010-11-29", "yyyy-MM-dd");
var myDate4 = Date.parseExact("2010-29-11", "yyyy-dd-MM");
