API

Just like getItem() but you can pass an array with the keys that need to be retrieved.

 var keys = ['asdf','asap','async'];
localforage.getItems(keys).then(function(results) {
  console.log(results);
  // prints:
  // {
  //   asdf: 'asdf value!',
  //   asap: 'asap value!',
  //   async: 'async value!'
  // }

  console.log(results.asdf);
  console.log(results['asdf']);
  console.log(results[keys[0]]);
  // all the above print 'asdf value!'
});

Invoking getItems() without arguments (or with null as the first argument) will retrieve all the items of the current driver instance.

 localforage.getItems().then(function(results) { });
// or by using callbacks
localforage.getItems(null, function(results) { });
