I think you want to use hasClass()

$('li.menu').hasClass('active');

You can retrieve all elements having the 'active' class using the following:

$('.active')

Checking wether or not there are any would, i belief, be with

if($('.active').length > 0)
{
    // code
}

$('li.menu.active')

is the simplest way. This will return all elements with both classes.

Or an already answered jQuery hasClass() - check for more than one class

You can use the hasClass method, eg.

$('li.menu').hasClass('active') // true|false

Or if you want to select it in one go, you can use:

$('li.menu.active')

Pure JavaScript answer:

document.querySelector('.menu').classList.contains('active');

Might help someone someday.

FYI: While your answer appears plausible, it has appeared in the 'low quality posts' queue after being flagged for deletion. I suspect this is because it is a code only answer without explanation. – Oliver Matthews Jun 12 '14 at 13:20

$(document).ready(function()
{
  changeColor = $(.active).css("color","any color");
  if($(".classname").hasClass('active')) {
  $(this).eq(changeColor);
  }
});

Welcome to Stack Overflow! Whilst this code snippet is welcome, and may provide some help, it would be [greatly improved if it included an explanation](//meta.stackexchange.com/q/114762) of *how* and *why* this solves the problem. Remember that you are answering the question for readers in the future, not just the person asking now! Please [edit] your answer to add explanation, and give an indication of what limitations and assumptions apply. – Toby Speight Feb 10 '17 at 12:52

If Condition to check, currently class active or not

$('#next').click(function(){
    if($('p:last').hasClass('active'){
       $('.active').removeClass();
    }else{
       $('.active').addClass();
    }
});

i wrote a helper method to help me go through all my selected elements and remove the active class.

    function removeClassFromElem(classSelect, classToRemove){
      $(classSelect).each(function(){
        var currElem=$(this);
        if(currElem.hasClass(classToRemove)){
          currElem.removeClass(classToRemove);
        }
      });
    }

    //usage
    removeClassFromElem('.someclass', 'active');
