考虑使用 https://github.com/axemclion/IndexedDBShim

IndexedDB Polyfill Build Status A polyfill to enable IndexedDB using WebSql.

IndexedDB is not supported on all browsers. This IndexedDB polyfill exposes the IndexedDB API in unsupported browsers using WebSQL. This shim is basically an IndexedDB-WebSql adapter.

More details about the project at gh-pages

Using this polyfill, you can use a single offline storage API across browsers (Opera, Safari, Firefox, Chrome and IE10) and even mobile devices (Phonegap on iOS and Android).

目前状态

• 已完成localstorage层
• 已完成websql的建表

[i5ting]

var collection = new Collection('message_test');

        collection.use_websql();

        var obj = {
            type :'type',
            mid :'mid',
            uid :'uid',
            uname :'uname',
            avatar :'avatar',
            sid :'sid',
            sname:'sname',
            timestamp :'timestamp',
            msg :'msg'
        }
        // ok
        collection.add(obj);
        // ok
        collection.save();
