Jquery getting class from a custom attribute in a tag

Question

I am trying to check if an attribute has a certain class on it:

$('span[last="lastWord"')

The above is what I have now. I want to check the span class with that attribute for its classes attribute... Basically what I'd like is a jQuery function to check that span class for a certain class. Hope that makes sense.

As @Pekka points out in the comments, jQuery already has a method hasClass that allows you to do this:

$('span').hasClass('yourClass');

Otherwise, you can do it in plain JS like:

// assuming you already have a reference to your element
function hasClass(elem, myClass) {
    return elem.classList.indexOf(myClass) !== -1;
}
