jquery each for objects

Question

<script>
    $(document).ready(function() {
        var data = { "programs": [ { "name":"zonealarm", "price":"500" }, { "name":"kaspersky", "price":"200" } ] };
        $.each(data.programs[0], function(key,val) {
            alert(key+val);
        });
    });
</script>

This code retrieves the first data. name:zonealarm and price:500.

How can I retrieve all the data in the object?

I tried $.each(data.programs, function(key,val) but it didn't work.

Should I put it in a loop?
