Question

Hello there am trying to save news tweets into three different array which are dynamically created.

am finding trouble when i want to get the text from each one of those array and make another request to twitter.

    news_tweets("reuters","1652541",3);
    function news_tweets(query, user_id,count) {
        news_array = [];
        $.getJSON("https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=false&user_id=" + user_id + "&count="+count+
        "&callback=?",
        function (data) {
      for (var i = 0; i < count; i++) {
          var user = data[i].user.name;
          var date = data[i].created_at;
          var profile_img = data[i].user.profile_image_url;
          var text = data[i].text;
          var url = (data[i].entities.urls.length > 0 ? data[i].entities.urls[0].url : '');
          news_array[i] = [{user:user,date:date,profile_img:profile_img,text:text,url:url}];
        }  
      for (var i = 0; i < news_array.length; i++) {
          for (var x=0; x<i.length; x++){
              console.log(news_array[i][x].user);
              }
            }
        });
    }

It doesn’t show anything on the console.log.

thanks for the help!!!!!

First, make sure that your count is smaller than the data array’s length, otherwise this could lead to some undefined values:

for (var i = 0; i < count && i < data.length; i++) …

Then, why are you creating all those one-element-arrays in the news_array? Just use only objects.

This would solve your actual issue: You are looping wrong over those inner arrays. The correct code would be

for (var i = 0; i < news_array.length; i++) {
    for (var x = 0; x < news_array[i].length; x++){
        console.log(news_array[i][x].user);
    }
}

Also, you should indent your code properly. You have some odd braces around, which don’t make the code readable.
