javascript regexp, validating date problem

Question

I have some code for validating date below:

function validateForm() {
var errFound = 0;       
//var patt_date = new RegExp(\"^((((19|20)(([02468][048])|([1         


        

Answer 1

This javascript code validates date exactly. You can copy it and test it in your browser.

 var regDate = '^(19[0-9]{2}|2[0-9]{3})-(0[1-9]{1}|1[0-2]{1}){1}-(0[1-9]|(1|2)[0-9]|3[0-1]){1}$';
 var txt='2010-01-31';
 if(txt.match(regDate))
 {
    alert('date match');
 }
