I've been working on a WordPress site for a client/friend. He wanted some custom generated content so I used Javascript. However, by default Javascript is disabled in WordPress. Thankfully GoDaddy support had the answer.

We're not using GoDaddy for hosting but they still came through with a good answer so I want to give them credit. I used method 1.
In addition to giving proper credit, this post will serve as a reminder to me what was done to get Javascript working on his site. Changing the theme and possibly updating the theme will likely break this fix.
