Hi All,

I want to enable/disable save button after 8 fields validation in my page.
I have old technique:- that is keep a boolean flag for every field(in our case 8 flags), update corresponding field(when the fileld is valid/invalid) and check, if all the flags are true then only "enable/disable" save button.

My question is do we have any better approach, like using one variable.


I am very thankful for any suggestions/solutions.

Thanks,
Praneeth

You don't need any variables at all. Have a change handler on the form that checks to see if the validation requirements are met, and change the state of the button if so.
 
It is sorta covered in the JavaRanch Style Guide.
