Intrepreting/Parsing JSON data with jQuery getJSON

Question

I would like to interpret data from JSON feed using jQuery getJSON.

$(function() {
    $.getJSON('http://gdata.youtube.com/feeds/users/raywilliamjohnson/uploads?alt=json-in-script&callback=showMyVideos2&max-results=30', function(data) { 
        $.each(data.feed.entry, function(i, item) {
            updated = item.updated;
            url = item['media$group']['media$content']['url'];
            thumb = item['media$group']['media$thumbnail'][0]['url'];
            numViews = item['yt$statistics']['viewCount'];
        });
    });
});

How to correctly interpret JSON data and assign variables to data items (ex. url, numViews, etc...)? Thanks much in advance for any help.

You need to set the callback GET parameter to ? (callback=?), so jQuery will be able to make the JSONP request correctly and execute your callback.

Also to get the url, you need to access the item at index [0], just like you get the thumb:

$(function() {
    $.getJSON('http://gdata.youtube.com/feeds/users/raywilliamjohnson/uploads?alt=json-in-script&callback=?&max-results=30', function(data) { 
        $.each(data.feed.entry, function(i, item) {
            var updated = item.updated;
            var url = item['media$group']['media$content'][0]['url'];
            var thumb = item['media$group']['media$thumbnail'][0]['url'];
            var numViews = item['yt$statistics']['viewCount'];
            // ...
        });
    });
});
