Using a clientscript, is it possible to revert back the old value if the condition is false

const scopeId = clientLib.*isValidForPackUpdate*(context);

           

const validScopeId = cfg.ONSITE_DAYS_REQUESTED.*indexOf*(*parseInt*(scopeId)) != -1;

           

if (!validScopeId) {

               

dialog.*alert*({

                   

title: 'My System',

                   

message: cfg.ERROR_MESSAGE.INVALID_PACKS.MESSAGE

               

});

               

return false;

           

}

you need to keep track of the old value yourself

i see thanks @battk
