Question

$.getJSON('https://graph.facebook.com/BogdanErimia/posts/?access_token=xxxxx&date_format=U&limit=17&callback=?', function(feed) {
    $.each(feed.data, function(index, item){
        $('.tweet').append('<div class="item-normal"><div class="normal"><div id="story2">' + item.message + '</div></div><div class="twitterbg"></div></div>');
        if ( index == 10 ) return false;
    });
});

There are some items in the feed without this “message”, and for them give me “undefined” error. I want to hide it please…

Answer 1

Check if(item.message) before you append a row. You may want to use a counter now, to check when you hit the 10th row.

$.getJSON('https://graph.facebook.com/BogdanErimia/posts/?access_token=xxxxx&date_format=U&limit=17&callback=?', function(feed) {
    var counter = 0;
    $.each(feed.data, function(index, item){
        if(item.message){
           $('.tweet').append('<div class="item-normal"><div class="normal"><div id="story2">' + item.message + '</div></div><div class="twitterbg"></div></div>');
           counter++;
        }
        if ( counter === 10 ) return false;
    });
});
