Here is an example to get 400 comments using JS, JQuery + SC SDK.
SC.get('/tracks/' + track.id + '/comments',{ limit: page_size }, function(comments) {
for (var i = 0; i < comments.length; i++) {
$('#result').append(comments[i].created_at + ': ' + comments[i].body + '<br/>');
}
});
SC.get('/tracks/' + track.id + '/comments',{ limit: page_size, offset: page_size}, function(comments) {
for (var i = 0; i < comments.length; i++) {
$('#result').append(comments[i].created_at + ': ' + comments[i].body + '<br/>');
}
});
