The result
read-only property of the IDBRequest
interface returns the result of the request. If the request failed and the result is not available, an InvalidStateError
exception is thrown.
var myResult = request.result;
any
The following example requests a given record title, onsuccess
gets the associated record from the IDBObjectStore
(made available as objectStoreTitleRequest.result
), updates one property of the record, and then puts the updated record back into the object store. For a full working example, see our To-do Notifications app (view example live.)
var title = "Walk dog"; // Open up a transaction as usual var objectStore = db.transaction(['toDoList'], "readwrite").objectStore('toDoList'); // Get the to-do list object that has this title as it's title var objectStoreTitleRequest = objectStore.get(title); objectStoreTitleRequest.onsuccess = function() { // Grab the data object returned as the result var data = objectStoreTitleRequest.result; // Update the notified value in the object to "yes" data.notified = "yes"; // Create another request that inserts the item // back into the database var updateTitleRequest = objectStore.put(data); // When this new request succeeds, run the displayData() // function again to update the display updateTitleRequest.onsuccess = function() { displayData(); }; };
