keyrange-shorthand.js

var myKeyRange = customers.makeKeyRange({
  upper: 'M',
  excludeUpper: true
});

keyrange.js

setup-shorthand.js

indexes: [
  { name: 'lastname' }

  onStoreReady: refreshTable,
  indexes: [
    { name: 'lastname', keyPath: 'lastname', unique: false, multiEntry: false }

});

write-access-cursor.js

var onItem = function(dataObj, cursor, transaction){

    var deleteRequest = cursor.delete(); // request deletion of current object
    deleteRequest.onsuccess = function(evt){ /* ... */ };
