【问题描述】：

I want to delete data with index but I am getting error. If I delete directly with objectstore without index, there is no problem, but what I need is to delete with index.

Database screenshot

Create Db Function

var objectStore = db.createObjectStore(\"rooms\", { keyPath: \"id\", autoIncrement: true });
        let index = objectStore.createIndex(\'floorIndex\', [\'floorIndex\']);

Delete Function

var floorIndexValue = \"2\";
    const request = window.indexedDB.open(\"AdminDatabase\");

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



      const txnRoom = db.transaction(\'rooms\', \'readwrite\');
      const storeRoom = txnRoom.objectStore(\'rooms\');

   
      const index = storeRoom.index(\'floorIndex\');

      let query = index.delete([floorIndexValue]);

      query.onerror = function (event) {
        console.log(\" Room Delete Error DB: \" + event);

      };
      query.onsuccess = function (event) {
        console.log(\" Room Delete Succes DB: \" + event);

      };
    };
