如何以编程方式删除WebSQL中的数据库？(How to delete a database in WebSQL programmatically?)

我是Web SQL数据库的新手，我用它来将数据保存在网页的本地数据库中。

我可以创建一个数据库

var db = openDatabase('database', '1.0', 'my database', 2 * 1024 * 1024);

我可以通过这样做创建一个表

db.transaction(function (tx) { tx.executeSql('CREATE TABLE IF NOT EXISTS mytable (blah,blah)'); });

我可以删除 表

db.transaction(function (tx) { tx.executeSql('DROP TABLE mytable'); });

但是有没有办法以编程方式删除database ？

I am new to Web SQL database and I use it to save data in a local database in a web page.

　I can create a database by

var db = openDatabase('database', '1.0', 'my database', 2 * 1024 * 1024);

　and I can create a table by doing this

db.transaction(function (tx) { tx.executeSql('CREATE TABLE IF NOT EXISTS mytable (blah,blah)'); });

　I can delete the table by

db.transaction(function (tx) { tx.executeSql('DROP TABLE mytable'); });

　but is there a way to delete the database programmatically?

规格说：

4.1数据库

每个来源都有一组相关的数据库。 每个数据库都有一个名称和一个当前的版本。 没有办法枚举或删除此API可用于源的数据库 。

Spec says:

4.1 Databases

Each origin has an associated set of databases. Each database has a name and a current version. There is no way to enumerate or delete the databases available for an origin from this API.
