I have wrote this and my teacher says my function is correct but when I asked her why it does not work instead of telling my what I did wrong she offered to let me do this with out using regular expression. I would like to know what I have done wrong. this is what the assignment was
Create a Web page that contains a text box in which users can enter a date. Also include a button that executes the test() method to validate the date against a regular expression. Write a regular expres-sion pattern that allows users to enter a one- or two- digit month, one- or two- digit date, and two- or four- digit year. Also, allow users to separate the month, date, and year by using either dashes or for-ward slashes. Users should be able to enter any of the following date formats: 11- 2- 07, 1- 25- 2007, or 01/ 25/ 2007.
This is what I have
