// Let us open our database
const DBOpenRequest = window.indexedDB.open("toDoList", 4);
// these two event handlers act on the database
// being opened successfully, or not
DBOpenRequest.onerror = (event) => {
note.appendChild(document.createElement("li")).textContent =
"Error loading database.";
};
DBOpenRequest.onsuccess = (event) => {
note.appendChild(document.createElement("li")).textContent =
"Database initialized.";
// store the result of opening the database in the db variable. This is used a lot below
db = DBOpenRequest.result;
// This line will log the version of the connected database, which should be "4"
console.log(db.version);
};
