Count Indexed Database Entries with Specific Service ID and Status
To log the count of the result, you can modify the code as follows:
const transaction = dbo.transaction(['orders'], 'readonly');
const objectStore = transaction.objectStore('orders');
const index = objectStore.index('serviceid, status');
const request = index.getAll([window['serviceid'], 0]);
request.onsuccess = function(event) {
const result = event.target.result;
const count = result.length;
console.log(count);
};
This code creates a transaction, retrieves the object store and index, and executes a 'getAll' query with the specified criteria. The 'onsuccess' event handler is used to retrieve the result and log the count of the result array.
