Wikipedia viewer, how to go through the json data


Can’t figure out how to go through this json data. I’ve tried to do a for loop but I guess that data is not an array because using index numbers doesn’t work. Also I’ve tried to use the forEach function but no luck their either.

have you tried a for…in loop?

I can’t quite remember the data received from the wiki api but it may go something like this:

 for (var i in data.result) console.log(data.result[i])


maybe you need to parse?


that seems promising but I cant get it working.

According to this it looks to me like this for…in is ment for going through the properties inside an object but I have a list of 10 individual objects and need somehow to loop through all of them one by one.


okay, you are almost there :slight_smile: you are still displaying the object, you need to show the items inside the object. try outputting results[i].title and see what happens


hey that worked! thanks a lot. Dont really understand how that works, have to look into it


I just noticed that now the search result are in “wrong” order, this is of course due to the way that for…in goes through the data, do you happen to know if there is a way to change this? top to bottom —> bottom to top
