[alex.allah]

Method #1

$('.someClass1').each(function(){
        // Some stuff here
});

$('.someClass2').each(function(){
        // Some stuff here
});

$('.someClass3').each(function(){
        // Some stuff here
});

Method #2

$('.someClass1, .someClass2, .someClass3, .someClass4').each(function()
{

        var el = $(this);

        if (el.hasClass('someClass1'))
        {
                // Some stuff here
        }

        if (el.hasClass('someClass2'))
        {
                // Some stuff here
        }

        if (el.hasClass('someClass3'))
        {
                // Some stuff here
        }
});
