页面下方从左向右移动的节日气氛图片

从左到右移动的圣诞节庆祝图标，JS代码：

<script language="javascript" type="text/javascript">    

(function() {

    if(new Date().getDate() !== 25) return;

    var sUrl = 'TempFile/christmas.gif';

        setTimeout(function() {

            var nWidth = document.body.scrollWidth - 342;//减去342是防止从页面右部出去的时候，出现横向滚动条

            var oImg = document.createElement("IMG");

            oImg.src = sUrl;

            oImg.border = 0;

            document.body.appendChild(oImg);

            oImg.style.position = "absolute";

            oImg.style.zIndex = 999;

            oImg.style.left = "-200px";

            oImg.style.bottom = "0px";

            oImg.title = "Merry Christmas!";

            var nTimer,f; 

            (function() {

                f = arguments.callee;

                nTimer = setTimeout(function() {

                    var nLeft = parseInt(oImg.style.left, 10);

                    if (nLeft > nWidth) {

                        document.body.removeChild(oImg);

                    } else {

                        oImg.style.left = nLeft + 5 + "px";

                        f();

                    }

                },

                50);

            })();

            $(oImg).bind("mouseover",

            function() {

                clearTimeout(nTimer);

            });

                f();

            });

        },

        3000);

})();
