{{APIRef("IndexedDB")}}{{deprecated_header}}{{non-standard_header}}
The isAutoLocale read-only property of the {{domxref("IDBIndex")}} interface returns a boolean value indicating whether the index had a locale value of auto specified upon its creation (see the options parameter to IDBObjectStore.createIndex().)
A boolean value.
In the following example we open a transaction and an object store, then get the index lName from a simple contacts database. We then open a basic cursor on the index using {{domxref("IDBIndex.openCursor")}} — this works the same as opening a cursor directly on an ObjectStore using {{domxref("IDBObjectStore.openCursor")}} except that the returned records are sorted based on the index, not the primary key.
The isAutoLocale value is logged to the console.
function displayDataByIndex() {
tableEntry.textContent = "";
const transaction = db.transaction(["contactsList"], "readonly");
const objectStore = transaction.objectStore("contactsList");
const myIndex = objectStore.index("lName");
console.log(myIndex.isAutoLocale);
myIndex.openCursor().onsuccess = (event) => {
const cursor = event.target.result;
if (cursor) {
const tableRow = document.createElement("tr");
for (const cell of [
cursor.value.id,
cursor.value.lName,
cursor.value.fName,
cursor.value.jTitle,
cursor.value.company,
cursor.value.eMail,
cursor.value.phone,
cursor.value.age,
]) {
const tableCell = document.createElement("td");
tableCell.textContent = cell;
tableRow.appendChild(tableCell);
}
tableEntry.appendChild(tableRow);
cursor.continue();
} else {
console.log("Entries all displayed.");
}
};
}
