Question

I’m not sure how to target the element I want in this case:

  var $div = $(".row-container").filter(function() {
        return $(this).data("i") == product_id;
        // where value == product id to find
      });

Now, within $div is an element that has the class 'price-row' which is what I want. $div.hasClass('price-row') only returns true or false value.

Answer 1

Use .find if it’s a child element:

var $div = $(".row-container").filter(function() {
    return $(this).data("i") == product_id; // where value == product id to find
}).find('.price-row');

If you meant that the matching element will be within that set, include it in the criteria to begin with:

var $div = $(".row-container.price-row").filter(function() {
    return $(this).data("i") == product_id; // where value == product id to find
});
