Cordova / Sqlite foreign keys

I am trying to run a simple example using Cordova and sqlite

here is my javascript code `

var dbName = "PresentationDB";
var dbVersion = "1.0";
var bdSize = 100000;
var displayName = "TTPresentationDB";
var db = null;

var app = {

// Application Constructor
initialize: function() {
    this.bindEvents();
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function() {
    document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
//
// The scope of 'this' is the event. In order to call the 'receivedEvent'
// function, we must explicitly call 'app.receivedEvent(...);'
onDeviceReady: function() {
    app.receivedEvent('deviceready');
    db = createdb();
    alert(db);
    db.transaction(populatedb,errorCallBack,successCallBack);

 },
// Update DOM on a Received Event
receivedEvent: function(id) {
    //var parentElement = document.getElementById(id);
    //var listeningElement = parentElement.querySelector('.listening');
    //var receivedElement = parentElement.querySelector('.received');

    //listeningElement.setAttribute('style', 'display:none;');
    //receivedElement.setAttribute('style', 'display:block;');

    console.log('Received Event: ' + id);
}



};

app.initialize();


function createdb()
{

 if (!window.openDatabase)
 {
   alert("Your browser does not support openDatabase");
 }
 alert("creating db..");
 return window.openDatabase(dbName, dbVersion, displayName, bdSize);

 }


function populatedb(tx)
{
tx.executeSql('CREATE TABLE IF NOT EXISTS PAGE (id_page INTEGER PRIMARY KEY 
AUTOINCREMENT , title VARCHAR(255), description TEXT, num_visits DATE,  
last_visited DATE)');

tx.executeSql('CREATE TABLE IF NOT EXISTS CONTENT (id_content INTEGER PRIMARY 
KEY AUTOINCREMENT, id_page )');
tx.executeSql('CREATE TABLE IF NOT EXISTS ARTICLE (id_article INTEGER PRIMARY 
KEY AUTOINCREMENT, title VARCHAR(255), text TEXT, description TEXT)');

tx.executeSql('INSERT INTO PAGE (title, description, num_visits, 
last_visited) VALUES ("First Page", "Test Page", CURRENT_TIME, 
CURRENT_TIME)');
tx.executeSql('INSERT INTO CONTENT (id_page) VALUES (1)');
tx.executeSql('INSERT INTO ARTICLE (title, text, description, id_page) VALUES 
("Article 1 Page 1", "Test Article", 1)');
tx.executeSql('INSERT INTO ARTICLE (title, text, description, id_page) VALUES 
("Article 2 Page 1", "Test Article", 1)');


}

function successCallBack()
{
    alert("Sucess");
    //alert("Returned rows = " + results.rows.length);
}


 function errorCallBack(tx, err)
 {
  alert("Error : " + err );
 }

function queryDB(tx)  
{
   tx.executeSql('SELECT * FROM DEMO', [], querySuccess, errorCB);

}

`

the lines when i add a foreign key are causing the error, is there any way to create relational database for SQLITE and Cordova ?
