IDBIndex.locale

Экспериментальная возможность: Это экспериментальная технология
Так как спецификация этой технологии ещё не стабилизировалась, смотрите таблицу совместимости по поводу использования в различных браузерах. Также заметьте, что синтаксис и поведение экспериментальной технологии может измениться в будущих версиях браузеров, вслед за изменениями спецификации.

The locale read-only property of the IDBIndex interface returns the locale of the index (for example en-US, or pl) if it had a locale value specified upon its creation (see createIndex()'s optionalParameters.) Note that this property always returns the current locale being used in this index, in other words, it never returns "auto".

Syntax

js
var myIndex = objectStore.index("index");
console.log(myIndex.locale);

Value

Example

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 IDBIndex.openCursor — this works the same as opening a cursor directly on an ObjectStore using IDBObjectStore.openCursor except that the returned records are sorted based on the index, not the primary key.

The locale value is logged to the console.

js
function displayDataByIndex() {
  tableEntry.innerHTML = "";
  var transaction = db.transaction(["contactsList"], "readonly");
  var objectStore = transaction.objectStore("contactsList");

  var myIndex = objectStore.index("lName");
  console.log(myIndex.locale);

  myIndex.openCursor().onsuccess = function (event) {
    var cursor = event.target.result;
    if (cursor) {
      var tableRow = document.createElement("tr");
      tableRow.innerHTML =
        "<td>" +
        cursor.value.id +
        "</td>" +
        "<td>" +
        cursor.value.lName +
        "</td>" +
        "<td>" +
        cursor.value.fName +
        "</td>" +
        "<td>" +
        cursor.value.jTitle +
        "</td>" +
        "<td>" +
        cursor.value.company +
        "</td>" +
        "<td>" +
        cursor.value.eMail +
        "</td>" +
        "<td>" +
        cursor.value.phone +
        "</td>" +
        "<td>" +
        cursor.value.age +
        "</td>";
      tableEntry.appendChild(tableRow);

      cursor.continue();
    } else {
      console.log("Entries all displayed.");
    }
  };
}
