网页飘浮、浮动元素使用CPU占用过高，如何用javascript语句清除释放对象？

Question

如果那广告是flash，关闭时可把它停止播放

Answer 1

不是flash广告，是纯图片的
如何清除定时器？下面是一段漂浮广告代码//瓢浮广告
document.write("<div id=\"SiteMove\" style=\"position:absolute\">");
document.write("<a href=\"#\" target=\"_blank\"><IMG border=\"0\" src=\"/wdwj/images/ggtp/pfgg.gif\"  width=\"100\" height=\"100\" border=\"0\"></a><br><a href=JavaScript:; onclick=\"SiteMove.style.display = 'none'\">关闭</a>");
document.write("</div>");var x = 50,y = 60;
var xin = true, yin = true;
var step = 1;
var delay = 30;
var obj=document.getElementById("SiteMove");
function floatAD() {
var L=T=0;
var R= document.body.clientWidth-document.getElementById("SiteMove").offsetWidth;
var B = document.body.clientHeight-document.getElementById("SiteMove").offsetHeight;
document.getElementById("SiteMove").style.left = x + document.body.scrollLeft;
document.getElementById("SiteMove").style.top = y + document.body.scrollTop;
x = x + step*(xin?1:-1); 
if (x < L) { xin = true; x = L} 
if (x > R){ xin = false; x = R} 
y = y + step*(yin?1:-1) 
if (y < T) { yin = true; y = T } 
if (y > B) { yin = false; y = B } 
}
var itl= setInterval("floatAD()", delay) 
obj.onmouseover=function(){clearInterval(itl)} 
obj.onmouseout=function(){itl=setInterval("floatAD()", delay)}
// JavaScript Document
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("lovexin12").style.top=parseInt(document.getElementById("lovexin12").style.top)+percent+"px";
document.getElementById("lovexin14").style.top=parseInt(document.getElementById("lovexin12").style.top)+percent+"px";lastScrollY=lastScrollY+percent; 
//alert(lastScrollY);
}

Answer 2

在关闭的那里改成:
this.parentElement.parentElement.removeChild(document.getElementById("SiteMove"));
试试，不过在移除之前要clearInterval(itl)一下写成函数:
function closeDiv(o){
    if(itl!=null) clearInterval(itl);
    o.parentElement.parentElement.removeChild(document.getElementById(this.parentElement.id));
}改一下关闭那地方:
document.write(" <a href=\"#\" target=\"_blank\"> <IMG border=\"0\" src=\"/wdwj/images/ggtp/pfgg.gif\"  width=\"100\" height=\"100\" border=\"0\"> </a> <br> <a href=JavaScript:; onclick=\"closeDiv(this)\">关闭 </a>"); 这样子去试试

Answer 3

o.parentElement.parentElement.removeChild(document.getElementById(this.parentElement.id)); 
好像可以改成
o.parentElement.parentElement.removeChild(this.parentElement); 

Answer 4

汗死了，o.parentElement.parentElement.removeChild(o.parentElement); 这样子

Answer 5

现在把飘浮去掉了，只有对联和浮标，再请教一下如何将这两种给kill掉，谢谢
代码如下://对联广告// JavaScript Document
lastScrollY=0;
function heartBeat(){ 
var diffY;
if (document.documentElement && document.documentElement.scrollTop)
    diffY = document.documentElement.scrollTop;

    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);

function bottomscroll(){ 
var diffadY;

    diffadY = document.documentElement.scrollTop;

document.write(bottomhtml + bottomhtml1); 
window.setInterval("bottomscroll()",1);

Answer 6

<a href=JavaScript:; onclick=\"bottomAD.style.display = 'none';bottomAD1.style.display = 'none'\">关闭浮标 </a> 这个，改成onclick="closeDiv1()"function closeDiv1(){
    var bp=document.getElementById("bottomAD").parentElement;
    var bp1=document.getElementById("bottomAD1").parentElement;
    bp.removeChild(document.getElementById("bottomAD"));
    pb1.removeChild(document.getElementById("bottomAD1"));
}
对联同样
function closeDiv2(){
    var bp=document.getElementById("lovexin12").parentElement;
    var bp1=document.getElementById("lovexin14").parentElement;
    bp.removeChild(document.getElementById("lovexin12"));
    pb1.removeChild(document.getElementById("lovexin14"));
}
