Hello,
Is it possible to dispose or clear all local storage items after a period of time, when the app closes or at log off? I am not sure this is very important to keep this data but I don't think it is harmful to keep, more of less was thinking about house cleaning.
Thanks.
Hello Casey,
You can use JS code:
codelocalStorage.clear(); /code
to clear local storage item. Invoke this code on logout_service "success" event, for example.
Worked great, Thanks.
What if I don't use a logout service but want to clear local storage when the app is closed?
Im not sure in Appery because I have not tried but could you use session storage if you want to clear storage when mobile browser is closed??
Casey,
Please read more about localStorage here http://devcenter.appery.io/documentat...
Well looks like you can use Session Storage. Thanks for info.. Im just learning HTML5 so this is nice.
Upon a successful login, I'm currently passing a response parameter "sessionToken" to a local storage variable "userSessionToken" via mapping. I don't have a logout service but I'd like to clear this local storage variable "userSessionToken" when the app is closed.
Casey, from the documentation on session storage it looks like this clears when the page is refreshed or navigated away from. I'm talking about on app exit only.
Hi Mike,
Unfortunatly there is no "exit" event in phonegap(platform feature).
You can read about avaliable phone gap events here and make logic you need on this base.

For example you can try solution from following topic based on "resume" and "pause" events:

okay got it.. If I happen to come across anything I will send it your way.. Good Luck.. Maybe you know this but there is an expiration on the session tokens. Session token lifetime is 120 minutes. Thereafter the key is not valid.
