如何编写正则表达式来验证日期？

我想出了这个：

function isValidDate(inputDate){    var myRegex = /^(d{1,2})([-/])(d{1,2})2(d{4}|d{2})$/;    var match = myRegex.exec(inputDate);    if (match != null) {        var auxDay = match[1];        var auxMonth = match[3] - 1;        var auxYear = match[4];        auxYear = auxYear.length < 3 ? (auxYear < 70 ? '20' + auxYear : '19' + auxYear) : auxYear;        var testingDate = new Date(auxYear,auxMonth,auxDay);        return ((auxDay == testingDate.getDate()) && (auxMonth == testingDate.getMonth()) && (auxYear == testingDate.getFullYear()));    } else return false;}

适用于

dd-mm-yyyy

dd-mm-yy

d-m-yyyy

d-m-yy
