How to get a youtube playlist using javascript API and json

Question

This is part of my youtube project. I try to extract video information from JSON format but I have problem in this line:

var videoId = data.feed.entry[i].li         


        

Answer 1

Simplified the solution and got rid of the string manipulation stuff.

var playListURL = 'http://gdata.youtube.com/feeds/api/playlists/B2A4E1367126848D?v=2&alt=json&callback=?';
var videoURL= 'http://www.youtube.com/watch?v=';

var vids = new Array();

$.getJSON(playListURL, function(data) {
    $.each(data.feed.entry, function(i, item) {
        vids.push( item["media$group"]["yt$videoid"]["$t"] );
    });

    console.log( vids );
});
