Examples
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();
};
};
