There are markup elements, for example li tags, which are in rotation and are alternately assigned and removed the class "active". How can I track class changes and if the class has changed, for example, from "active" to "current", call another function? Climb into the script rotator is not possible.

    If css classes are assigned using the jquery addClass function, then it is enough just to overwrite it, and thus intercept the call:

    var origFn = $.fn.addClass; $.fn.addClass = function(className) { // Выполняем здесь необходимый нам код // и вызываем оригинальную функцию origFn.apply(this, arguments); }

      but that's not $.fn.val but still probably $.fn.addClass - GLAGOLA

    Operate in logical expressions with something like this:


    Next - a matter of technology ...

      If there are not very many of them, launch the function when loading the page, which will collect the values ​​of the classes of these elements into an array.

      Then, once a second (for example), again loop over the elements and compare with the array, run all we need, the new values ​​- into the array. And in a circle.
