[jQuery] Loop through JSON data and check for each option specified

[Thomas Jaggi]

Let's say I have on object with my options:
options = jQuery.extend({
        title: 'xy',
        date: 'xy'
}, opts);

And some JSON data:
({ "items": [
        {
                "title": "IMGP3817",
                "date": "2008-10-18T10:35:17-08:00"
        },
        {
                "title": "IMGP3826",
                "date": "2008-10-18T11:18:19-08:00"
        }
] })

Now I want to loop through each item and check for each option (e.g.
with indexOf). How to do this?

This doesn't work:
$.getJSON("wheremydatais", function(data){
        $.each(data.items, function(i,item){
                $.each(options, function(key,val){
                        if (item.key.indexOf(options.key) != -1) {
                                console.log('everything ok');
                        }
                });
        });
});
