Best way to allow field changes if user belongs to group A?

[Snehal13]

Should I use ACL or go for client scripting.

My requirement: if user is part of group A then only allow to update field.  Else not

@Snehal13 

best way is to create field level WRITE ACL and use advanced script

answer = gs.getUser().isMemberOf('Group A');

Another way is to use Display business rule and use g_scratchpad variable and then use onLoad client script
