LocalStorage(string | variable)
Description
LocalStorage allows you to save string data so it is available next time you run the program. An entry can be created by assigning to LocalStorage.variableName, where variableName is chosen by you. Data is retrieved the same way. A program is allowed to store at least 5 megabytes of data in LocalStorage. The information in LocalStorage is lost if the browser cache is cleared. To be certain that you do not lose data, save it into an SQLite database instead.
LocalStorage is shared among all apps deployed from the same web server. This can be useful if you have a family of apps which need to share data.
Note that if the user has Private Browsing turned on, localStorage is not accessible.
Example
Rem LocalStorage Save Example localStorage.data = "This is Data." (run and exit program) Rem LocalStorage Retrieve Example Print localStorage.data Rem Test if Private Browsing is turned on Try localStorage.private = "test" Catch err MsgBox "Please turn Private Browsing on" End Try
Output
This is the Data. 1
