How to use jQuery hasClass when the selector is a JS variable

Question

I am trying to use jQuery's hasClass function. It doesn't seem to work when I use it like this. I would appreciate it if anyone can work out how to use hasClass in this situation.

The error I am getting is

numValueElement.hasClass is not a function
if($(numValueElement.hasClass("tag")))

The key line throwing this error is this one if($(numValueElement.hasClass("tag")))

$(".numberValue").click
    (
        function ()
        {
            var numValueElement = this;
            var propertyId = numValueElement.id;
            $(".numberBounds").filter("#"+propertyId).toggle();
            if($(numValueElement.hasClass("tag")))
            {
            }

        }
    );

.hasClass() is a jQuery object method, not something attached to the element itself.

You need to know the difference between a jQuery object wrapped element, and a plain DOM element.

What you want is:

$(numValueElement).hasClass("class-name")
