Client side validation gives the user instant notification of any errors before anything is submitted to the server. But since javascript can be disabled or even totally bypassed by typing the url of the form's action= value in the browser's navigation bar you really should have at least server side validation for any form data sent to a server side script.

Whether the form's method is POST or GET, you can still by pass any client side validation.

I alway use and recommend to others to use XHTML.

In terms of using AJAX, it doesn't matter. AJAX is simply a particular technique in using javascript.

validating in js is to check out each & every field considering which type of data the particular element holds
