I have a private web based app where sometimes I genuinely ask to the users what they want to do in given situations. To do so, I'm using the confirm function of javascript.
As any other modal box, after a few popups the user has the choice to disable them by simply clicking the little box as showed below:
The problem is that, if they clicked it once, they never see other messages and responses to confirm are assumed 0, which is confusing because basically it means that all the actions requiring their confirmation are cancelled with no warning! Refreshing the page does not help, they have to close it and reopen it for it to work again.
Can I detect when they checked that little box?
