How to use in jQuery :not and hasClass() to get a specific element without a class

Question

I have this line of code:

$(\'#sitesAccordion .groupOfSites\').click(function() {
    var lastOpenSite = $(this).siblings().hasClass(\':not(.closedTab)\');
    c         


        

Answer 1

jQuery's hasClass() method returns a boolean (true/false) and not an element. Also, the parameter to be given to it is a class name and not a selector as such.

For ex: x.hasClass('error');
