forerunnerdb - 新的 ForerunnerDB() 命令后现有的 ForerunnerDB 数据库被清除

Question

无法让 ForerunnerDB 加载现有数据。浏览器刷新后，执行新的 ForeRunnerDB() 命令后，整个 IndexedDB 数据库将从 Chrome 资源中消失。

var fdb = new ForerunnerDB();
// Existing database disappears from Chrome resources here

var db = fdb.db('VRC');
db.collection('videos').load();
var videoCollection = db.collection('videos');

if (!videoCollection.count()) {

    videoCollection.setData([
    {
        "_id": 1,
        "name": "Joe"
    },
    {
        "_id": 2,
        "name": "Susan"
    }]);

    // Yeah, I know this is redundant...
    videoCollection.save();
    db.save();
    ForerunnerDB.save();
}

Answer 1

通过将函数传递给 Collection.load() 解决了问题:

videoCollection.load(function() {
    // Do something with data here
});
