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

var date=/^[0-9]{1,2}\-[0-9]{1,2}\-[0-9]{1,4}$/;

if(!date.test(form.date.value))

alert("Enter correct date");

else
alert(" working");
