通过jQuery验证日期字符串格式的最佳方法
问题描述:
如果是日期,我发现了很多验证字符串的链接。
I found a lot of links to validate string if it is a date.
但无论如何我无法弄清楚如果我们有这个东西验证:
But anyway I cannot figure out how to validate if we have this thing:
6/6/2012 首先 6 是月,第二 6 是天
如果用户输入的话:
06/06/2012
如何以正确的方式完成任务?
Any clue how it could be done in a proper way?
谢谢!!

在这里,这应该适用于任何具有4位数年份和任何分隔符的日期格式。我从我的插件理想表格中提取它,验证日期等等。
Here, this should work with any date format with 4 digit year and any delimiter. I extracted it from my plugin Ideal Forms which validates dates and much more.
var isValidDate = function (value, userFormat) {
var
userFormat = userFormat || 'mm/dd/yyyy', // default format
delimiter = /[^mdy]/.exec(userFormat)[0],
theFormat = userFormat.split(delimiter),
theDate = value.split(delimiter),
isDate = function (date, format) {
var m, d, y
for (var i = 0, len = format.length; i < len; i++) {
if (/m/.test(format[i])) m = date[i]
if (/d/.test(format[i])) d = date[i]
if (/y/.test(format[i])) y = date[i]
}
return (
m > 0 && m < 13 &&
y && y.length === 4 &&
d > 0 && d <= (new Date(y, m, 0)).getDate()
)
}
return isDate(theDate, theFormat)
}
