My problem is simple, but incredibly frustrating as I'm now on my second week of trying to figure this out and on the verge of giving up. I would like to retrieve my 'notesObject' variable outside my getAllNotes() function when after the transaction.oncomplete() listener executes.
(function() {
// check for IndexedDB support
if (!window.indexedDB) {
console.log(`Your browser doesn't support IndexedDB`);
return;
}
// open the CRM database with the version 1
let request = indexedDB.open('Notes', 1);
// create the Contacts object store and indexes
request.onupgradeneeded = (event) => {
let db = event.target.result;
// create the Notes object store ('table')
let store = db.createObjectStore('Notes', {
autoIncrement: true
});
// create an index on the sections property.
let index = store.createIndex('Sections', 'sections', {
unique: true
});
}
function insertData() {
let myDB = indexedDB.open('Notes');
myDB.onsuccess = (event) => {
// myDB.transaction('Notes', 'readwrite')
event.target.result.transaction('Notes', 'readwrite')
.objectStore('Notes')
.put({
sections: "New Note",
pages: "New page",
lastSelectedPage: ""
});
console.log("insert successful");
}
myDB.onerror = (event) => {
console.log('Error in NotesDB - insertData(): ' + event.target.errorCode);
}
myDB.oncomplete = (event) => {
myDB.close();
console.log('closed');
}
}
insertData()
function getAllNotes() {
let myDB = indexedDB.open('Notes');
let notesObject = [];
myDB.onsuccess = (event) => {
let dbObjectStore = event.target.result
.transaction("Notes", "readwrite").objectStore("Notes");
dbObjectStore.openCursor().onsuccess = (e) => {
let cursor = e.target.result;
if (cursor) {
let primaryKey = cursor.key;
let section = cursor.value.sections;
notesObject.push({
primaryKey,
section
})
cursor.continue();
}
}
dbObjectStore.transaction.onerror = (event) => {
console.log('Error in NotesDB - getAllData() tranaction: ' + event.target.errorCode);
}
dbObjectStore.transaction.oncomplete = (event) => {
return notesObject;
console.log(notesObject)
}
}
}
let notes = getAllNotes()
console.log("Getting Notes sucessful: " + notes)
})()
I've tried setting global variables, but nothing seems to work. I am a complete noob and honestly, I'm completely lost on how to retrieve the notesObject variable outside my getAllNotes() function. The results I get are 'undefined'. Any help would be greatly appreciated.
