大家帮我看看这个代码在IE8里面怎么不显示？在firefox和opera都完美显示

(function($){
    $.fn.preview = function(){
        var xOffset = 10;
        var yOffset = 20;
        var w = $(window).width();
        $(this).each(function(){
            $(this).hover(function(e){
                $("body").append("<div id='preview'><div><img src='images/"+($(this).attr("id"))+".jpg'

/><p>"+"</p></div></div>");
                    $("#preview").css({
                    position:"absolute",
                    padding:"4px",
                    border:"1px solid #f3f3f3",
                    backgroundColor:"#eeeeee",
                    top:(e.pageY - yOffset) + "px",
                    zIndex:1000
                });
                $("#preview > div").css({
                    padding:"5px",
                    backgroundColor:"white",
                    border:"1px solid #cccccc"
                });
                $("#preview > div > p").css({
                    textAlign:"center",
                    fontSize:"12px",
                    padding:"8px 0 3px",
                    margin:"0"
                });
                if(e.pageX < w/2){
                    $("#preview").css({
                        left: e.pageX + xOffset + "px",
                        right: "auto"
                    }).fadeIn("fast");
                }else{
                    $("#preview").css("right",(w - e.pageX + yOffset) + "px").css("left", "auto").fadeIn

("fast");   
                }
            },function(){
                $("#preview").remove();
            }).mousemove(function(e){
                $("#preview").css("top",(e.pageY - xOffset) + "px")
                if(e.pageX < w/2){
                    $("#preview").css("left",(e.pageX + yOffset) + "px").css("right","auto");
                }else{
                    $("#preview").css("right",(w - e.pageX + yOffset) + "px").css("left","auto");
                }
            });                          
        });
    };
})(jQuery);
