So I start with items 1-4:

<div class=someDiv bold italic style=display: none;>Lorem</div>

<div class=someDiv regular italic style=display: block;>Lorem</div>

<div class=someDiv bold style=display: none;>Ipsum</div>

<div class=someDiv regular style=display: block;>Ipsum</div>

Then I have some input checkboxes:

<input class=regular type=checkbox />

<input class=bold type=checkbox />

<input class=italic type=checkbox />

So basically I have jQuery showing and hiding divs. Now I have another function that must iterate through these divs (one for each checkbox), and show/hide based on another criteria. But I don't want the already hidden divs to be shown again.

$(.someDiv).each(function(){

  if($(this).hasClass(regular)){

    $(this).show();

  } else {

    $(this).hide();

  };

In this example, the only remaining div should be the last div. Unfortunately, this code will make the second and fourth divs shown.

This code is very basic example of all the filters I'm going to be applying, adding etc.
