Get previous object in selectors chain

Question

I have the following jQuery calls chain:

$(someSelector).nextUntil(".specialClass").addClass(classBasedSomeSelectorObject)

I need to addClass that's value is based on the object which was returned by someSelector.

Is there any way to implement it?

Answer 1

Wrapping this in a function seems to be the simplest approach, something like this:

function(selector) {
  var class = selector == ".thing" ? "thingClass" : "defaultClass";
  $(selector).nextUntil('.specialClass').addClass(class);
}

Update based on comments:

$(selector).each(function() {
  var class = "class" + this.id; //whatever logic to get class here
  $(this).nextUntil('.specialClass').addClass(class);
});

Answer 2

$('someSelector').each(function() {
    $(this).nextUntil('.specialClass').addClass(/* calculation based on 'this' */);
});
