Project description
dojox.storage provides a JavaScript abstraction for persistent storage
as well as pluggable implementations which typically use native browser
extensions (e.g. Flash player, Gears)
-------------------------------------------------------------------------------
Dependencies:
FlashStorageProvider requires the Flash player
GearsStorageProvider requires the Gears extension
LocalStorageProvider does not require any plugins but will run only in certain
browsers (see below)
BehaviorStorageProvider does not require any plugins but will run only in IE 5+
CookieStorageProvider has no requirements
The various Air*StorageProviders require Adobe's AIR software
The open source mtasc compiler (www.mtasc.org) is needed to build the
ActionScript into SWF format. The SWF object is maintained within svn, so
this step is only necessary if Storage.as is modified. A sample build script
is provided (buildFlashStorage.sh)
-------------------------------------------------------------------------------
Documentation
See http://dojotoolkit.org/reference-guide/dojox/storage.html for Dojo Storage docs.
See dojox/storage/demos/helloworld.html for a simple Hello World example
you can base your code off of.
