I would recommend writing a small gears wrapper - that exposes a local storage interface but uses gears underneath. Something along the lines of:
(function()
{
if (!window.localStorage && google.gears)
{
var db = google.gears.factory.create('beta.database');
db.open('BackboneLocalData');
db.execute("CREATE TABLE IF NOT EXISTS persist_data (key TEXT UNIQUE NOT NULL PRIMARY KEY, value TEXT NOT NULL)").close();
var localStorage =
{
clear: function ()
{
db.execute('begin').close();
db.execute("DELETE FROM persist_data").close();
db.execute('commit').close();
},
setItem: function (key, value)
{
db.execute('begin').close();
db.execute("delete from persist_data where key = ?", [key]).close();
db.execute("insert into persist_data(key, value) VALUES (?, ?)", [key, value]).close();
db.execute('commit').close();
},
getItem: function (key)
{
db.execute('begin').close();
r = db.execute("SELECT value FROM persist_data WHERE key = ?", [key]);
ret = r.isValidRow() ? r.field(0) : null;
r.close();
db.execute('commit').close();
return ret;
}
};
window.localStorage = localStorage;
}
})(); One small issue with the above script: you wont be able to use square brackets with local storage. Iow you have to go localStorage.getItem("somekey") rather than localStorage["somekey"].
