Hi,

I'm wondering how I'm supposed to use the localStorage. I have this bit of code:

var car = {};
    car.wheels = 4;
    car.doors = 2;
    car.sound = 'vroom';
    car.name = 'Lightning McQueen';
    console.log( car );
    localStorage.setItem( 'car', car );
    console.log( localStorage.getItem( 'car.doors' ) );

    var oCars = localStorage.getItem( 'car' );
    $.each(oCars, function(key, value) {
        var sCurVal = oCars[key];
    });

Open in new window


The console.log doesn't show anything. This:
console.log( car );

just shows [Object object]

This:
    console.log( localStorage.getItem( 'car.doors' ) );

comes out null

The .each doesn't step through.

What am I missing?

Thank you!

You can't store an array in local storage.
You can stringify the array for storage
Then parse it back when you need it.
Or just store the items separately.

Try this, seems to work fine., I'm just alerting the values,
<script>
var car = {};
    car.wheels = 4;
    car.doors = 2;
    car.sound = 'vroom';
    car.name = 'Lightning McQueen';

localStorage.setItem( 'car', JSON.stringify(car) );

oCars = JSON.parse(localStorage['car']);

    $.each(oCars, function(key, value) {
        alert(oCars[key])
    });
</script>

Open in new window
