[janani13]

Hi all, Im using JS to check the date and month validation. If i give 08-14-1949 the month value return as 0 not as 8 and the same problem for 09-14-1983. These two month value is considered as 0. I cant resolve it. Please help me. Code.

    function checkyear(source, arg) {
        var txtDOB = arg.Value;
        var birthdate = txtDOB.split("/");
        var yearvalue = parseInt(birthdate\[2\]);
        var MonthValue = parseInt(birthdate\[0\]);
        var DayValue = parseInt(birthdate\[1\]);
        var date = new Date();
        alert(yearvalue);
        alert(MonthValue);
        alert(DayValue);
        var CurrentYear = date.getFullYear();
        if (MonthValue < 1 || MonthValue > 12) {
            alert(MonthValue);
            source.errormessage = "Please enter a valid Date of birth";
            arg.IsValid = false;
            return;
        }
        if (DayValue < 1 || DayValue > 31 || (MonthValue == 2 && DayValue > daysInFebruary(yearvalue))) {

            alert(DayValue);
            source.errormessage = "Please enter a valid Date of birth";
            arg.IsValid = false;
            return;


        }
        if (yearvalue >= CurrentYear - 13) {

            source.errormessage = "Your age should be greater than 13.";
            arg.IsValid = false;
            return;
        }
        else if ((yearvalue <= 1900) || (yearvalue >= CurrentYear)) {
            source.errormessage = "Please enter a valid Date of birth";
            arg.IsValid = false;
            return;
        }
        else {
            arg.IsValid = true;
        }
    }
    function daysInFebruary(year) {
        // February has 29 days in any year evenly divisible by four,
        // EXCEPT for centurial years which are not also divisible by 400.

        return (((year % 4 == 0) && ((!(year % 100 == 0)) || (year % 400 == 0))) ? 29 : 28);
        alert(((year % 4 == 0) && ((!(year % 100 == 0)) || (year % 400 == 0))) ? 29 : 28);
    }

Why do you require all this code?? Why dont you use

var myDate=new Date();
myDate.setFullYear(2000,0,23); //to set date (23th January 2000)

Now you can use

myDate.getMonth();
myDate.getDay();

etc.. and make your life easy. On your case the Culprit is parseInt. It has a bug, if you parseInt(08) it returns 0 rather than 8. The easy fix would be

parseInt(08 * 1)

. This will fix your issue. cheers.. :thumbsup:
