So we should use a new regular expression to forbid underscopes. Next, we want to permit only passwords that contain letters and at least one numeral.

For that we use the seacrh() method and two more regular expressions: /(a-z) / and /(0-9)/.

If its not blank, we check the length of the string and permit only usernames that are between 5 and 15 characters.

Next, we use the Java Script regular expression /\W/ to forbid illegal characters from appearing in usernames.

No need to write even a single Java Script line for simple form validation.

If the element complies than sufunction returns an empty string.

Otherwise it returns a message describing the error and highlight appropriate element with yellow.

In actual fact the setup of these fields is the most simple of all form fields to validate as radio buttons set one value that only needs to be tested when the form is submitted.If you run a validation of the users form input before the form is submitted, there will be no wait time and redundant load on the server."Bad data" are already filtered out when input is passed to the server-based program. Client side form validation usually done with javascript.validate Email ( ) Next we want to see if the email address the user entered is real.This means that the input data must contain at least an @ sign and a dot (.).
