IDBObjectStore.name

此屬性可以返回當前物件倉庫的name屬性值，也就是名稱。

通過createObjectStore()方法建立物件倉庫時，第一個引數規定名稱。

語法結構：

let objectStoreName = IDBObjectStore.name;

用法比較簡單，看如下程式碼例項：

let request = window.indexedDB.open("antzone", 1);
request.onupgradeneeded = (ev) => {
  let db = ev.target.result;
  if (!db.objectStoreNames.contains('students')) {
    let objectStore = db.createObjectStore('students',{keyPath:"id"});
    objectStore.createIndex("xingbie","sex",{ unique: false });
  }
}

request.onsuccess = (ev) => {
  let db = ev.target.result;
  let transaction = db.transaction(['students'], 'readonly');
  let objectStore = transaction.objectStore('students');
  console.log(objectStore.name);
}

程式碼執行效果截圖如下：

上述程式碼可以列印出物件倉庫的名稱。
