You can try with this example,

$(window).mouseover(function(event){
    var x = event.pageX,
        y = event.pageY,
        scX = $(window).scrollLeft(),
        scY = $(window).scrollTop(),
        scMaxX = scX + $(window).width(),
        scMaxY = scY + $(window).height(),
        wd = $("#div1").width(),
        hgh = $("#div1").height();

    if (x + wd > scMaxX) x = scMaxX - wd;
    if (x < scX) x = scX;
    if (y + hgh > scMaxY) y = scMaxY - hgh;
    if (y < scY) y = scY;
    $("#div1").css({'top': y, 'left': x});  
});
