var open = indexedDB.open("MyDatabase", 1);
open.onupgradeneeded = function(){
var db = open.result;
var store = db.createObjectStore("MyTableName", {keyPath: "id"});
var index = store.createIndex("NameIndex", ["name.last", "name.first"]);
};
open.onsuccess = function(){
// Start a new transaction
var db = open.result;
var tx = db.transaction("MyTableName", "readwrite");
var store = tx.objectStore("MyTableName");
var index = store.index("NameIndex");
// Add some data
store.put({id: 0001, name: {first: "Brenden", last: "Eich"}, age: 58});
store.put({id: 0002, name: {first: "Dennis", last: "Ritchie"}, age: 70});
store.delete(0002);
// Query to get all data
var getAll = store.getAll();
getAll.onsuccess = function(){
for(i=0; i<getAll.result.length; i++)
x.innerHTML += getAll.result[i].id + ". " +getAll.result[i].name.first + " <br>";
}
getAll.onsuccess = function(){
for(i=0; i<getAll.result.length; i++)
x.innerHTML += getAll.result[i].id + ". " +getAll.result[i].name.first + " <br>";
