如何删除 indexedDB 中的对象存储？

Question

I can't find in documentation information about deleting object store, not object on store and not a database, namely deleting the object store. Is there such a possibility?

Answer 1

Documentation: https://developer.mozilla.org/en-US/docs/Web/API/IDBObjectStore/clear

First, you need to create a transaction to IndexedDB instance specifying the access options to the table. Since you want to manipulate, set: "readwrite" option for mode: IDBTransactionMode , then the name of the table you want to drop, in my case its called "photos_os" .

function dropTable() {
    const objectStore = db.transaction('photos_os', "readwrite").objectStore('photos_os');
    const objectStoreRequest = objectStore.clear();

    objectStoreRequest.onsuccess = function(event) {
        console.log('Erase of database completed.');
    };
}
