You have to implement a JavaScript program for the validation case
Question- Write a JavaScript program for the validation case using the RegExp method.
Validate Date of Birth
a-The user must enter a DOB in the format mm/dd/yyyy/
b-The validation is a two-step process as described below.
c-Your program must validate the format first as given:
d-The part "mm", "dd", and "yy" cannot be "00", "00", and "0000" respectively.
e-The part "mm" must be two-digits such as "01 through 09" or "10 or 11 or 12".
f-The part "dd" must be two-digits such as "01 through 09" or "10 through 31".
g-The part "yyyy" must be between "1900 through 2099" inclusive.
h-Once the format has been validated, the next step is to verify the following:
i-The year entered cannot be greater than the current year (e.g., 2014)
j-If the year entered is the current year, then the day entered cannot be greater than today's date.
k-The date entered must follow these rules, <= if the month is February, <=30 if the month entered is: September, April, June, and November. <=31 for the remaining months.
Full Rating given to whoever can give the JavaScript code to satisfy these needs in the RegExp format.
