New Post: Task list hierarchies?

Hi,

I'm trying to make a web page using JQuery and SPServices that walked through a Sharepoint 2013 Task List, and display it in a specialized HTML table. I can get to the task name, assignee, etc, without problem.

I can't seem figure out which field contains the "hierarchy" (i.e. summary tasks vs child tasks) information. I've tried:

$(this).attr("ows__Level");

and

$(this).attr("ows__FileDirRef");

Neither seem to contain what I want (Level is always "1"). Anybody know where the information is hidden?

Thanks,
John
