Evening everybody.
I am developing a basic complaint management system. A consumer can complaint anything about the company. A staff of the company wants to reply the complaint back.
My question is, how can a 'Reply' link changed to 'Replied' link after the staff has already replied the complaint? I don't expect any coding but I just want to know the correct syntax on how to do it. Is that true that it can only be done using JavaScript ?
Any guide ?
