我不能更新IndexedDb中的任何数据。当我运行代码时，它说“store.put不是store.onsuccess中的函数”。

• 我尝试从许多浏览器，在所有相同的错误
• 我还尝试了.update而不是.put函数，但它不起作用，并给出相同的错误

const request = window.indexedDB.open("AdminDatabase");

    request.onsuccess = (event) => {
      const db = event.target.result;

      const txn = db.transaction('floors', 'readwrite');

      const store = txn.objectStore('floors').get(parseInt(getRoomButtonNumber));
    
      store.onsuccess = function (event) {
        var floorDataFromDb = event.target.result;
        console.log("RenameFloor: getDbResult: FloorName: " + floorIdFromDb.Name);

        floorDataFromDb.Name = person;

        console.log("RenameFloor: Json New Name: " + floorDataFromDb.Name);

        //In this line caught error

        store.put(floorDataFromDb);

        store.onsuccess = function (event) {
          console.log("floorData Updated: " + event.target.result);

        }

      };

      store.onerror = function (event) {
        console.log("GET Error DB: " + event);

      };
    };
