谁有网页漂浮电话客服的代码呀，具体是：在网页的右侧居中，只能上下移动的。不需要点击跳转的。还有就是怎么把代码加入网页。谢谢啊！

<SCRIPT LANGUAGE="JavaScript"><!--function initEcAd() {document.all.AdLayer2.style.posTop = -200;document.all.AdLayer2.style.visibility = 'visible'MoveRightLayer('AdLayer2');}function MoveLeftLayer(layerName) {var x = 5;var y = 340;var diff = (document.body.scrollTop + y - document.all.AdLayer1.style.posTop)*.40;var y = document.body.scrollTop + y - diff;eval("document.all." + layerName + ".style.posTop = parseInt(y)");eval("document.all." + layerName + ".style.posLeft = x");setTimeout("MoveLeftLayer('AdLayer1');", 20);}function MoveRightLayer(layerName) {var x = 5;var y = 340;var diff = (document.body.scrollTop + y - document.all.AdLayer2.style.posTop)*.40;var y = document.body.scrollTop + y - diff;eval("document.all." + layerName + ".style.posTop = y");eval("document.all." + layerName + ".style.posRight = x");setTimeout("MoveRightLayer('AdLayer2');", 20);}
document.write("<div id=AdLayer2 ><img src=xxxxx/freestyle.jpg></div>");initEcAd()//--></SCRIPT>这段代码 放在你需要放的网页的最下面就ok了 然后再换一个图片
