qq懸浮代碼(兼容各個浏覽器)。需要的朋友可以過來參考下，希望對大家有所幫助
代碼如下: <script language="JavaScript" type="text/javascript"> lastScrollY=0; function heartBeat(){ var diffY; if (document.documentElement && document.documentElement.scrollTop) diffY = document.documentElement.scrollTop; else if (document.body) diffY = document.body.scrollTop else {/*Netscape stuff*/} //alert(diffY); percent=.1*(diffY-lastScrollY); if(percent>0)percent=Math.ceil(percent); else percent=Math.floor(percent); document.getElementById("ad_left").style.top=parseInt(document.getElementById ("ad_left").style.top)+percent+"px"; document.getElementById("ad_right").style.top=parseInt(document.getElementById ("ad_left").style.top)+percent+"px"; lastScrollY=lastScrollY+percent; //alert(lastScrollY); } function hidead(num) { showad = false; if(num==1) document.getElementById("ad_left").style.display="none"; else if(num==2) document.getElementById("ad_right").style.display="none"; } var ClosebuttonHtml1 = '<div style="position: absolute;bottom:0px;right:25px;margin:2px;padding:2px;z-index:2000;"><a href="javascript:void(0);" onclick="hidead(1)" style="color:#ffffff;text-decoration:none;font-size:12px;">關閉</a></div>'; var ClosebuttonHtml2 = '<div style="position: absolute;bottom:0px;right:25px;margin:2px;padding:2px;z-index:2000;"><a href="javascript:void(1);" onclick="hidead(2)" style="color:#ffffff;text-decoration:none;font-size:12px;">關閉</a></div>'; ad1="<div id=/"ad_left/" style='right:10px;POSITION:absolute;TOP:160px;'></div>" ad2="<DIV id=/"ad_right/" style='right:10px;POSITION:absolute;TOP:160px;'><br><a href='tencent://message/?uin=758541860&Menu=yes'><img height='120' src='../images/qq.gif' border='0' width='110'></a></div>"; document.write(ad1); document.write(ad2); window.setInterval("heartBeat()",1); </script>
