I have an app where user goes through a number of steps in different tabs such as filling forms, making selections etc. Tables are updated by ajax.
I want to be able to figure out user changes between tabs so that if a user moves from one tab to next without making changes a modal will ask him if he is sure he wants to go to the next step without completing previous. I am thinking to do this by checking certain session variables and since I don't want to refresh page I want to use ajax. Does anyone know how this is possible??
How can I send session variables in my ajax responses??
