well in non compliant browsers.

This
article discusses client-side validation using jQuery's validation
plugin. That is, you will use JavaScript to validate the fields before

before adding it into the database.
In the tutorial you will create
a form that contains four fields: name, e-mail, comment and URL. The
first three fields are required, whereas the URL field is optional.
And, if you submit the form without filling in the required fields, you
will be prompted with an error message.

hidden image, if it fails, it will show the appropriate message.
