Question

How do you check if the class that is assigned to a div? For example, I want to check if a div has a class of header-link then it should alert a message box similar to this:

$('.header a').click(function()
{
    if($(this).classname == 'header-link')
    {
        alert('the element has the class name already');
    }
    else
    {
        $(this).addClass('header-link');
    }
});

The classname I put in there is an example I need to make it check if it has the class assigned or not… (even when jQuery has assigned it dynamically).

Sounds like you want .hasClass()

$('.header a').click(function()
{
    if($(this).hasClass('header-link'))
    {
        alert('the element has the class name already');
    }
    else
    {
        $(this).addClass('header-link');
    }
});
