Add ajax response (html with content) to DOM

Add ajax response (html with content) to DOM

I am trying to set up an instant search. I have the ajax call setup. The response is a json string containing the HTML of the searchresults. My question now is, how can I add this to the DOM?  The html is an full table with content.

What I do at the moment is this: 
  1. if (results.errcode == 200) {
  2. $('div#vrijwilligers').add(results.content);
  3. }
