Javascript Date Validation ( DD/MM/YYYY) & Age Checking

Question

I\'ve started to work on Javascript recently. What I am testing is checking the DoB in valid format. Next step will be checking the age.

What my HTML code includes

Answer 1

If you want to use forward slashes in the format, the you need to escape with back slashes in the regex:

   
var dateformat = /^(0?[1-9]|1[012])[\/\-](0?[1-9]|[12][0-9]|3[01])[\/\-]\d{4}$/;
