Get formatted HTML from CKEditor

I'm using CKEditor in my web app, and I'm at a loss as to how to get the contents of the editor with HTML formatting.

var objEditor = CKEDITOR.instances["sectionTextArea"];
var q = objEditor.getData();

This will get me the text entered in CKEditor, without any markup.

However,

var q = objEditor.getHTML();

will return a null value. What am I doing wrong?
