正则表达式之时间验证

正则表达式之时间验证

正则表达式：

var reg = 
/^(?:(?!0000)[0-9]{4}-(?:(?:0[1-9]|1[0-2])-(?:0[1-9]|1[0-9]|2[0-8])|(?:0[13-9]|1[0-2])-(?:29|30)|(?:0[13578]|1[02])-31)|(?:[0-9]{2}(?:0[48]|[2468][048]|[13579][26])|(?:0[48]|[2468][048]|[13579][26])00)-02-29)
(\T)
(([0-1]{1}[0-9]{1})|([2]{1}[0-4]{1}))
([:])
(([0-5]{1}[0-9]{1}|[6]{1}[0]{1}))
([:])
([0-5]{1}[0-9]{1}|[6]{1}[0]{1})$/

验证格式：

2080-02-10T12:60:30

验证demo：

<html>
<script>
function IsDate() {
             //输入的日期
var reg = /^(?:(?!0000)[0-9]{4}-(?:(?:0[1-9]|1[0-2])-(?:0[1-9]|1[0-9]|2[0-8])|(?:0[13-9]|1[0-2])-(?:29|30)|(?:0[13578]|1[02])-31)|(?:[0-9]{2}(?:0[48]|[2468][048]|[13579][26])|(?:0[48]|[2468][048]|[13579][26])00)-02-29)(\T)(([0-1]{1}[0-9]{1})|([2]{1}[0-4]{1}))([:])(([0-5]{1}[0-9]{1}|[6]{1}[0]{1}))([:])([0-5]{1}[0-9]{1}|[6]{1}[0]{1})$/
            var str = document.getElementById("date").value;
            var arr = reg.test(str);
            if (str == "") {
                alert("请输入日期");
            }

            else if(!arr){
                  alert("请输入正确的日期格式，例：2080-02-10T12:60:30");
            }else{
                  alert("日期格式正确");
            }
}
</script>
<body>
    输入您要验证的日期：<input type="text" id="date" name="date" />
    <br />
    <br />
    <input type="button" id="btnValid" value="验证日期格式" onclick="IsDate()"/>
</body>

测试用例：

2012-04-20T12:12:12 √ 2012-12-20T12:12:12 √ 2012-13-20T12:12:12 ×  (判断一年多少个月)
2012-04-30T12:12:12 √ 2012-04-32T12:12:12 × (判断一个月多少天)
2000-2-29T12:60:30  × 2000-02-29T12:60:30 √ 2000-02-30T12:12:12 × (判断平年闰年)
2017-12-25T12:23:23 √ 2017-12-25T24:23:23 √ 2017-12-25T26:23:23 × (判断小时)
2017-12-25T12:59:23 √ 2017-12-25T24:60:23 √ 2017-12-25T12:62:23 × (判断分钟)
2017-12-25T12:59:59 √ 2017-12-25T24:60:60 √ 2017-12-25T12:62:63 × (判断秒)
