Q:

Get new window height after jQuery AJAX

I feel like the answer to this question is going to be embarrassingly simple, but it's eating up a lot of time and I can't see the solution. I'm making a simple infinite scroll function, and need the script to recognize the new height of the window after loading more content. The value is always the same as first load time. I based this latest code on another answer here, but it's still not working. Thoughts?
var scrollFunction = function(){
        var myTop = jQuery(window).scrollTop();
        var myHeight = jQuery(window).height();
        if (myTop >= myHeight){ 
            $(window).unbind("scroll");
            jQuery.ajax({
                type: 'POST',
                url: '/ping/thumbs.php',
                data: 'foo=bar',
                success: function(data){
                    $(".thumbnails").append(data);
                    $(window).scroll(scrollFunction);
                },
                dataType: 'html'
            });
        };
    };
    $(window).scroll(scrollFunction);

A:

The height of the window is the size of the browser window.  You want the height of the body.  window height only changes when the browser is resized.
