WebSql transfer data to another webpage

Question

I want to return the same data from my WebSql database into another webpage test.html. But I currently do not know how to achieve that. I have also read this post on how to access web sql database between 2 html5 pages, but I dont really understand what I am supposed to do.

This is my code so far:

<h1>WebSQL Example</h1>
<form action="test.html">
<div id="controls">
    <p>Add a car to the database</p>
    <label>Make:</label>
    <input type="text" id="carmake" />
    <br />
    <label>Model:</label>
    <input type="text" id="carmodel" />
    <br />
    <input type="text" id="text" />
    <button type="button" id="addcar" onclick="addCar();">Add Car</button>
</div>
</form>
<div id="carlistholder">
     <h3>Your Cars</h3>

    <ul id="carlist"></ul>
</div>
<script>
//Test for browser compatibility
if (window.openDatabase) {
    //Create the database the parameters are 1. the database name 2.version number 3. a description 4. the size of the database (in bytes) 1024 x 1024 = 1MB
    var mydb = openDatabase("cars_db", "0.1", "A Database of Cars I Like", 1024 * 1024);

    //create the cars table using SQL for the database using a transaction
    mydb.transaction(function (t) {
        t.executeSql("CREATE TABLE IF NOT EXISTS help (id INTEGER PRIMARY KEY ASC, make TEXT, model TEXT, text TEXT)");
    });



} else {
    alert("WebSQL is not supported by your browser!");
}

//function to output the list of cars in the database

function updateCarList(transaction, results) {
    //initialise the listitems variable
    var listitems = "";
    //get the car list holder ul
    var listholder = document.getElementById("carlist");

    //clear cars list ul
    listholder.innerHTML = "";

    var i;
    //Iterate through the results
    for (i = 0; i < results.rows.length; i++) {
        //Get the current row
        var row = results.rows.item(i);

        listholder.innerHTML += "<li>" + row.make + " - " + row.model + " - " + row.text + " (<a href='javascript:void(0);' onclick='deleteCar(" + row.id + ");'>Delete Car</a>)";
    }

}

//function to get the list of cars from the database

function outputCars() {
    //check to ensure the mydb object has been created
    if (mydb) {
        //Get all the cars from the database with a select statement, set outputCarList as the callback function for the executeSql command
        mydb.transaction(function (t) {
            t.executeSql("SELECT * FROM test", [], updateCarList);
        });
    } else {
        alert("db not found, your browser does not support web sql!");
    }
}

//function to add the car to the database

function addCar() {
    //check to ensure the mydb object has been created
    if (mydb) {
        //get the values of the make and model text inputs
        var make = document.getElementById("carmake").value;
        var model = document.getElementById("carmodel").value;
        var text = document.getElementById("text").value;

        //Test to ensure that the user has entered both a make and model
        if (make !== "" && model !== "") {
            //Insert the user entered details into the cars table, note the use of the ? placeholder, these will replaced by the data passed in as an array as the second parameter
            mydb.transaction(function (t) {
                t.executeSql("INSERT INTO test (make, model, text) VALUES (?, ?, ?)", [make, model, text]);
            });
        } else {
            alert("You must enter a make and model!");
        }
    } else {
        alert("db not found, your browser does not support web sql!");
    }
}


//function to remove a car from the database, passed the row id as it's only parameter

function deleteCar(id) {
    //check to ensure the mydb object has been created
    if (mydb) {
        //Get all the cars from the database with a select statement, set outputCarList as the callback function for the executeSql command
        mydb.transaction(function (t) {
            t.executeSql("DELETE FROM test WHERE id=?", [id], outputCars);
        });
    } else {
        alert("db not found, your browser does not support web sql!");
    }
}

outputCars();
</script>
