在后台添加js特效可实现这样的效果。js代码为：<script language="JavaScript"><!--var no = 5//雪片数目var speed = 20//飘动速度。(值越大越慢)var ns4up = (document.layers) ? 1 : 0//当前浏览器类型，如果是NS则为1var ie4up = (document.all) ? 1 : 0//当前浏览器类型，如果是IE则为1var s, x, y, sn, csvar a, r, cx, cyvar i, doc_width = 800, doc_height = 600x = new Array()y = new Array()r = new Array()cx = new Array()cy = new Array()s = 8//每次下落的高度，越小越平滑，但是也越慢if (ns4up) { //以NS兼容方式doc_width = self.innerWidth//取页面宽度doc_height = self.innerHeight//取页面高度}elseif (ie4up) { //以IE兼容方式doc_width = document.body.clientWidth//取页面宽度doc_height = document.body.clientHeight//取页面高度}for (i = 0i <no++ i) { //根据前面定义的雪片数目写进相应数目的层initSnow()//随机初始化层的坐标if (ns4up) { //如果浏览器是NS//用layer作为雪片(星号)的容器document.write("<layer name=\"dot"+ i +"\" left=\"1\" ")document.write("top=\"1\" visibility=\"show\"><font color=\"red\">")document.write("*</font></layer>")}elseif (ie4up) { //如果浏览器是IE//用div作为雪片的容器document.write("<div id=\"dot"+ i +"\" style=\"POSITION: ")document.write("absoluteZ-INDEX: "+ i +"VISIBILITY: ")document.write("visibleTOP: 15pxLEFT: 15px\"><font color=\"red\">")document.write("*</font></div>")}}//初始化雪片，生成随机坐标function initSnow() {a = 6r[i] = 1sn = Math.sin(a)cs = Math.cos(a)cx[i] = Math.random() * doc_width + 1cy[i] = Math.random() * doc_height + 1x[i] = r[i] * sn + cx[i]y[i] = cy[i]}//计算雪花位置，从新位置上出现，看起来就像是新产生的一样。function makeSnow() {r[i] = 1cx[i] = Math.random() * doc_width + 1cy[i] = 1x[i] = r[i] * sn + cx[i]y[i] = r[i] * cs + cy[i]}//雪花下落的计算function updateSnow() {r[i] += sx[i] = r[i] * sn + cx[i]y[i] = r[i] * cs + cy[i]}//在NS浏览器上处理雪片下落的主程序function SnowdropNS() {for (i = 0i <no++ i) { //依次处理每片雪花updateSnow()//下落if ((x[i] <= 1) || (x[i] >= (doc_width - 20)) || (y[i] >= (doc_height - 20))) { //如果超出屏幕范围makeSnow()//则调整雪片到新位置上doc_width = self.innerWidth//更新页面宽度数据doc_height = self.innerHeight//更新页面高度数据}document.layers["dot"+i].top = y[i]//改变层的Y坐标，应用新的位置document.layers["dot"+i].left = x[i]//改变层的X坐标，应用新的位置}setTimeout("SnowdropNS()", speed)}//在IE浏览器上处理雪片下落的主程序function SnowdropIE() {for (i = 0i <no++ i) { //依次处理每片雪花updateSnow()//下落if ((x[i] <= 1) || (x[i] >= (doc_width - 20)) || (y[i] >= (doc_height - 20))) { //如果超出屏幕范围makeSnow()//则调整雪片到新位置上doc_width = document.body.clientWidth//更新页面宽度数据doc_height = document.body.clientHeight//更新页面高度数据}document.all["dot"+i].style.pixelTop = y[i]//改变层的坐标，应用新的位置document.all["dot"+i].style.pixelLeft = x[i]}setTimeout("SnowdropIE()", speed)//准备下一次下落过程。}if (ns4up) { //如果是NSSnowdropNS()//调用SnowdropNS使雪片下落}elseif (ie4up) { //如果是NSSnowdropIE()//调用SnowdropIE使雪片下落}--></script>说明：可以根据自己的需求根据说明进行相应参数的修改<div class="J_TWidget" data-widget-config="{'duration':0.1,'activeTriggerCls':'.tshop-psm-shop-ww-hover','interval':0.1,'effect':'scrollx','activeIndex':1,'navCls':'user-crzysj','contentCls':'user-crzysjii','autoplay':true}" data-widget-type="Carousel" style="position:relative"><ul class="user-crzysjii" style="display: nonewidth: 999999pxleft: 0pxposition: absolute"><li class="-_-switchable-panel-internal535 ks-switchable-panel-internal998" style="width: 475pxheight: 800pxdisplay: blockfloat: left"></li></ul><ul class="user-crzysj"><li class="-_-switchable-trigger-internal534 ks-switchable-trigger-internal997 tshop-psm-shop-ww-hover" style="width:475pxheight:800pxright:50%margin-right:505px"><embed allownetworking="all" allowscriptaccess="never" flashvars="scene=taobao_shop" height="1000" name="flashfirebug_1387778983714" src="http://img1.tbcdn.cn/tfscom/T1lmk2Fk8bXXXtxVjX.swf" type="application/x-shockwave-flash" width="475" wmode="transparent"></li></ul></div><div class="J_TWidget" data-widget-config="{'duration':0.1,'activeTriggerCls':'.tshop-psm-shop-ww-hover','interval':0.1,'effect':'scrollx','activeIndex':1,'navCls':'user-crzysj','contentCls':'user-crzysjii','autoplay':true}" data-widget-type="Carousel" style="position:relativez-index:99"><ul class="user-crzysjii" style="display: nonewidth: 999999pxleft: 0pxposition: absolute"><li class="-_-switchable-panel-internal635 ks-switchable-panel-internal1108" style="width: 475pxheight: 800pxdisplay: blockfloat: left"></li></ul><ul class="user-crzysj"><li class="-_-switchable-trigger-internal634 ks-switchable-trigger-internal1107 tshop-psm-shop-ww-hover" style="width:475pxheight:800pxleft:50%margin-left:505px"><embed allownetworking="all" allowscriptaccess="never" flashvars="scene=taobao_shop" height="1000" name="flashfirebug_1387778983652" src="http://img1.tbcdn.cn/tfscom/T1lmk2Fk8bXXXtxVjX.swf" type="application/x-shockwave-flash" width="475" wmode="transparent"></li></ul></div>直接在首页添加个自定义模块 编辑 点两个箭头的那个编辑代码模式 然后复制代码放进去 确定就好！
