LocalStorage
(Redirected from Localstorage)
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 on some devices. 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 off"
End Try
Rem Some additional samples:
localStorage.setItem("key", value) 'creates localStorage.key with defined value
localStorage["key"] = value 'alternative method for above
localStorage.getItem("key") 'calls localStorage.key...useful to check if it exists
localStorage.removeItem("key") 'deletes localStorage.key
delete localStorage.key 'alternative method for above
delete localStorage["key"] 'another alternative method for above
localStorage.clear() 'nuclear deletion of all localStorage variables in the domain. Use with care.
localStorage[DBRecords.rows.item(0)["ModsType"]] = "alpha"
Output
This is Data.
