Wikipedia API - Get random page with links

I know there is this code: generator=random to get a random page but it doesn't work with my code below :

http://en.wikipedia.org/w/api.php?action=parse&format=json&prop=text&page=Little_Richard&callback=?

This URL comes from this great article.

I have used action=parse, prop=text and page=Page_Name because it's the only way (that I found) to get the links with the text.

You can this the result of my whole code there (this code doesn't work on JSFiddle or CodePen).

Anybody know if there is a way to get a random page with this method ? Thanks in advance :)
