If you are using prototype, you can get (for example) all the divs  
with the $$ function and then disable the form elements, see  
[Prototype API Documentation | $$ (Deprecated URL)](http://www.prototypejs.org/api/utility/dollar-dollar).

Do you mean disable? If what you are trying to do is to prevent them  
from being posted when the form is submitted then disabling them is  
not what you need to do. As far as I know there is no way of  
preventing fields that have values from being posted though others may  
correct me on this. Why can you not just ignore the irrelevant fields  
when the form is submitted?

Sandip,  
you can set the the [html obj]'s style as:

html\_obj.style.display=“”;

I hope it will do…

Thanks, for reply !  
following trick worked for me…

I created one hidden div outside form tag and while submitting form  
appended  
unnecessary div ( with form elements )  
to the hidden div outside form tag.

JavaScript method

> outer\_hidden\_div.appendChild( unnnecessary\_div\_inside\_form\_tag )
