JavaScript中验证时间的正则表达式

最简单的正则 如 : /d{4}-/d{2}-/d{2}

但是实际并没有那么简单的哇!

//这是yyyy-mm-dd hh:mm:ss 的
var reg1=/^(d{4})-(d{2})-(d{2}) (d{2}):(d{2}):(d{2})$/;
//这是 yyyy-mm-ddde 的
var reg2=/^(d{4})-(d{2})-(d{2})$/;

验证时间格式为:2012-01-31 09:00:22

var reDateTime = /^(?:19|20)[0-9][0-9]-(?:(?:0[1-9])|(?:1[0-2]))-(?:(?:[0-2][1-9])|(?:[1-3][0-1])) (?:(?:[0-2][0-3])|(?:[0-1][0-9])):[0-5][0-9]:[0-5][0-9]$/;
var isDateTime = reDateTime.test('2012-01-31 09:00:22');

看看另外的一些参考的正则写法(时间相关的)

//日期的正则表达式
var reg = /^[1-9]\d{3}-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1])$/;
var regExp = new RegExp(reg);
if(!regExp.test(value)){
alert("日期格式不正确,正确格式为:2014-01-01");
return;
}
//时间的正则表达式
var reg = /^(20|21|22|23|[0-1]\d):[0-5]\d:[0-5]\d$/;
var regExp = new RegExp(reg);
if(!regExp.test(value)){
alert("时间格式不正确,正确格式为:12:00:00");
return;
}
//日期+时间的正则表达式
var reg = /^[1-9]\d{3}-(0[1-9]|1[0-2])-(0[1-9]|[1-2][0-9]|3[0-1])\s+(20|21|22|23|[0-1]\d):[0-5]\d:[0-5]\d$/;
var regExp = new RegExp(reg);
if(!regExp.test(value)){
alert("时间格式不正确,正确格式为: 2014-01-01 12:00:00 ");
return;
}
//正则表达式,认证小时和分钟
console.log(/^(?:(?:0?|1)\d|2[0-3]):[0-5]\d$/.test("19:20"));
//下面是可以为空的
console.log(/^(?:(?:0?|1)\d|2[0-3]):[0-5]\d$|^$/.test(""));

========================================

提供一个js验证日期比较全的正则表达式

               

我们在实际工作当中经常会遇到很多js验证日期正则表达式的项目,而很多人不知道改如何使用正则表达式来做javascript日期验证正则表达式,下面我就给大家提供一个本人收集的较全js验证日期正则表达式
