如何从JavaScript中删除整个IndexedDB数据库？

Question

如何从JavaScript中删除整个IndexedDB数据库,而不仅仅是一个对象存储？我正在使用IndexedDB垫片,它可能使用WebSQL作为其后端.

我主要想知道如何为PhantomJS(无头)浏览器执行此操作,尽管Chrome,Safari(在iPad上)和IE10是其他重要的浏览器.

据我所知,应该使用indexedDB.deleteDatabase:

var req = indexedDB.deleteDatabase(databaseName);
req.onsuccess = function () {
    console.log("Deleted database successfully");
};
req.onerror = function () {
    console.log("Couldn't delete database");
};
req.onblocked = function () {
    console.log("Couldn't delete database due to the operation being blocked");
};

我可以确认它适用于PhantomJS 1.9.0和Chrome 26.0.1410.43.
