On the server side, you can build a JavaScript array that dontains the
values that will be initially displayed in the form. The on the client side,
use an onsubmit function to compare each form value w/ its initial value
from the array.

> anybody suggest any way to know that the data in the form has
> changed(I
> do not want to again check with existing data).
> Any help is really appreciated. Thanks
