Random text fetch from Reddit

stech

Hello everyone.
I’m trying to display random text from random subreddits on my mirror. I have found a code that uses jQuery to fetch 10 titles from a page and that can be used successfully inside a html page.
Link to the function -> https://gist.github.com/sente/947491

The problem comes when I try to integrate that inside my module. So I try to fetch that data inside my function but using $ I don’t think it does the job. I have no idea how to call a jQuery function inside my script since the example uses a html page. I tried with the getScripts function but the result is the same.
My code right now looks like this

	randomQuote: function() {
		
		var script = document.createElement('script');
		script.src = 'http://j.mp/jqymin';
		script.type = 'text/javascript';
		document.getElementsByTagName('head')[0].appendChild(script);
	  
		var a=[];
		script.getJSON(
        "http://www.reddit.com/r/showerthoughts.json?jsonp=?",
        function foo(data)
        {
          script.each(
            data.data.children.slice(0, 10),
            function (i, post) {
              a.push(post.data.title);
            }
          )
        }
        
      )      
      return a;
	},

Any help would be much appreciated since I’m a noob with JavaScript, I’m just starting out.
