Array Problem

off.the.walls

Hi Everyone, so i'm working with a returned object from an api and its giving me the comments as long as I access them within a for loop. The only problem with this is that it creates an array for each comment instead of putting them all into one over all array. I know the solution is probably going to be something simple but right now my head is wrecked trying to figure it out. Can anyone spot a way around it? I've attached a screen grab of the returned object and attached the code.


While the name and id vars are in the code I haven't included them in the screenshot.


[HTML]
var coms = feed_comments;
var coms_data = coms.data;
for(var a = 0; a < coms_data.length; a++)
{

var com_id = coms_data[a].id
var com_message = coms_data[a].message;
var com_author = coms_data[a].from;
var com_author_name = com_author.name;
var com_author_id = com_author.id;
var com_likes = coms_data[a].like_count;
var com_time = coms_data[a].created_time;

var com_array = [com_id, com_message, com_author_id,
com_author_name, com_likes, com_time];

}
var com_main_array = [];
com_main_array.push(com_array);
console.log("MAIN COMMENTS: ",com_main_array);
[/HTML]





FOUND THE SOLUTION! The problem in this instance was that the loop was rewriting the main storage array every time. By storing the array before the loop then pushing to it within the loop it stored the data i need in it.

[HTML]
var coms = feed_comments;
var coms_data = coms.data;
var com_main_array = [];
for(var a = 0; a < coms_data.length; a++)
{
var com_id = coms_data[a].id
var com_message = coms_data[a].message;
var com_author = coms_data[a].from;
var com_author_name = com_author.name;
var com_author_id = com_author.id;
var com_likes = coms_data[a].like_count;
var com_time = coms_data[a].created_time;

var com_array = [com_id, com_message, com_author_id, com_author_name, com_likes, com_time];
// console.log("COMS ARRAy: ",com_array);
com_main_array.push(com_array);

}
console.log("MAIN ARRAY:",com_main_array);

Are the comments not being returned as objects? It essentially looks like an array of arrays. You could easily just manipulate the initial array to grab the comments and pop it into a new array on its on.

With this api i've got a returned object, with an array of objects, with keys that return either a value of another array, in those array are more objects and inside those objects are the data that I need. Haven't really worked with OOP that much in JS so still getting my head around it.

What are you trying to do with the data that's returned?

Just displaying it on a newsfeed. So posts and comments on the post.

Is this JSON data that's being returned from an API? If it is, have you looked at JSON.parse?
