前端JS脚本代码如下：
//获取网站热门点击排行

 

var cdsales=new ActiveXObject("Microsoft.XMLDOM"); //创建XmlDom对象
cdsales.async=true; //使用异步加载
cdsales.onreadystatechange=LoadedSales;
function LoadedSales()
{
    var txt="";
    if(cdsales.readyState==4)
    {
        if(cdsales.parseError.errorCode != 0)
        {
            txt="";
        }else{
            var bi=cdsales.documentElement.selectNodes("item");
            if(bi!=null&&bi.length>0)
            {
                for(var i=0;i<bi.length;i++)
                {   
                    txt+="<li>·<a href="+bi[i].childNodes[1].text+" style=color:"+bi[i].childNodes[2].text+">"+bi[i].childNodes[0].text+"</a></li>";
                }
            }else{
                txt="";
            }
        }
    }else{
        txt="";
    }   
    sales.innerHTML=txt;
}
function LoadSalesDoc()
{
    var Url="/XML/Hot.xml";
    cdsales.load(Url);
}
