This library alows you to do cross domain local storage.
It uses easyXDM to communicate between domains and Store.js to handle the local storage on the remote domain.
All the basic interactions are implemented except store.forEach() but you can get around that with store.getAll().
On the consumer side add these to your html header:
<script type="text/javascript" src="/js/easyXDM-2.4.19.3/easyXDM.min.js"></script>
<script type="text/javascript">
easyXDM.DomHelper.requiresJSON("/js/easyXDM-2.4.19.3/json2.js");
</script>
<script type="text/javascript" src="/js/XDStore.js"></script>
<script type="text/javascript">
var store = new XDStore("http://localhost/html/provider.html"); //remote path of the provider page
...
</script>The json is used to support old browsers. In javascript you can use the same commands from Store.js. Only they now have callbacks.
The provider side looks like this:
<!doctype html>
<html>
<head>
<script type="text/javascript" src="/js/easyXDM-2.4.19.3/easyXDM.min.js"></script>
<script type="text/javascript">
easyXDM.DomHelper.requiresJSON("/js/easyXDM-2.4.19.3/json2.js");
</script>
<script type="text/javascript" src="/js/store.js-1.3.16/store+json2.min.js"></script>
<script type="text/javascript" src="/js/XDStoreProvider.js"></script>
</head>
<body>
Magic iframe :O
</body>
</html>In the html map you can see examples of the consumer and provider page.
That's it.
