I have been building a trivia game. I had a working version but want to keep iterating and making improvements.
One thing I was trying tonight was separating out a function I had written that pulled data out of my JSON file and build a series of arrays, and then used those arrays to display question on the web page. It worked before I split it, but now that I have split it into two functions (buildQuestionList and askQuestion) the questions are coming back as undefined.
I think this might be an issue of variable scope but I am not sure why it isn't working.

I'd appreciate any help or advice!

10,815 PointsWell, I thought it was but apparently not! I was calling the initialize() function from the onclick behaviour in my HTML. I moved the code from the buildQuestionList into an $(document).ready function and it works now. Thanks for the tip! I am not totally sure why it wasn't firing properly the way I had it, but I am happy it works now.

10,815 PointsSure, @64yes, it is right here: http://davidjdrysdale.com/trivia/
It's working now but I am still looking to make improvements. The issue I want to resolve next is that the correct answers are accessible from the console if you access the correct variable. I have found a way to encrypt the answers but I've also been told it would be better to move checking to the server side. I don't know how to do that yet, so that's at the top of my list of things to learn.

10,815 PointsYep... Apparently NodeJS can solve this, so that's what I'm trying to learn now!

29,446 PointsI'am reading the code on mobile phone, so I might've missed it but do you ever fire your initialize function that should fetch the questions? I see it defined but I don't see where it's used :)
