Question

Not really sure how to phrase this question so it’s generic enough. (and will rephrase, after I know what I’m asking). The problem, I believe deals with variables in a JQuery .find() function.

Problem: you can wrap $() around an array of DOM elements, or around a jQuery object, but not around an array of jQuery objects

The best I can do, at this time, is provide an example here

The problem code in the previous fiddle, is here:

////////////////Neither of the following works////////////////
//nodelevel = nodesWithMinuses.find('div.node.level' + levelnumber);
  nodelevel = $(nodesWithMinuses).find('div.node.level' + levelnumber);
////////////////Neither of the previous works////////////////

Answer 1

Apparently you can wrap $() around an array of DOM elements, or around a jQuery object, but not around an array of jQuery objects.

Try changing this line:

var nodeWithMinus = thisplusminus.parent().parent();

to this:

var nodeWithMinus = thisplusminus.parent().parent()[0];

This will extract the DOM element and turn nodesWithMinuses into an array of DOM elements.
