可以單獨(dú)關(guān)閉的對(duì)聯(lián)廣告代碼

可以單獨(dú)關(guān)閉的對(duì)聯(lián)廣告代碼，直接放在頁(yè)面里就行了。我寫在JS文件里，調(diào)用不顯示。

<SCRIPT language="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("leftDiv").style.top = parseInt(document.getElementById("leftDiv").style.top)+percent+"px";
document.getElementById("rightDiv").style.top = parseInt(document.getElementById("rightDiv").style.top)+percent+"px";
lastScrollY=lastScrollY+percent;
//alert(lastScrollY);
}

window.setInterval("heartBeat()",1);
//-->
//關(guān)閉按鈕
function close_left1(){
left1.style.visibility='hidden';
}
function close_left2(){
left2.style.visibility='hidden';
}
function close_right1(){
right1.style.visibility='hidden';
}
function close_right2(){
right2.style.visibility='hidden';
}
//顯示樣式
document.writeln("<style type=\"text\/css\">");
document.writeln("#leftDiv,#rightDiv{background-color:#fff;position:absolute;}");
document.writeln(".itemFloat{height:auto;line-height:5px;}");
document.writeln("<\/style>");
//以下為主要內(nèi)容
document.writeln("<div id=\"leftDiv\" style=\"top:200px;left:5px\">");
//------左側(cè)各塊開始
//---L1
document.writeln("<div id=\"left1\" class=\"itemFloat\">");
document.writeln("<embed src=http://www.51edmonton.ca/ad/ad001.jpg></embed>");
document.writeln("<br><a href=\"javascript:close_left1();\" title=\"關(guān)閉上面的廣告\">×<\/a><br><br><br><br>");
document.writeln("<\/div>");

//------左側(cè)各塊結(jié)束
document.writeln("<\/div>");
document.writeln("<div id=\"rightDiv\" style=\"top:200px;right:5px\">");
//------右側(cè)各塊結(jié)束

//---R2
document.writeln("<div id=\"right2\" class=\"itemFloat\">");
document.writeln("<a target=_blank href=#><img border=0 src=http://www.51edmonton.ca/ad/ad001.jpg></a>");
