播放列表的生成是用循环进行控制的，正常的循环是从1－－1000 变量递增的话，

我就反起道而行将循环改为1000－－1 变量递减。代码如下：

正常代码：

<s cript language="JavaScript" >
<!–
var via = opener;
var write_via = "opener";
var iLoc = self.location.href;
function playSel(){via.wmpStop();via.startExobud();}
function refreshPl(){self.location=iLoc;}
function chkSel(){via.chkAllSel();refreshPl();}
function chkDesel(){via.chkAllDesel();refreshPl();}

function dspList(n){
var elmABlock = 20; // 设定每页可显示多少个播放项目
var totElm = via.intMmCnt;
var totBlock = Math.floor((via.intMmCnt-1) / elmABlock)+1;
var cblock;
if(n==null){cblock=1;} else {cblock=n;}
var seed;
var limit;
if(cblock < totBlock){
seed=elmABlock*(cblock-1); limit=cblock*elmABlock-1; //控制循环的 起始 0－19
} else {
seed=elmABlock*(cblock-1); limit=totElm-1;
}

if(via.intMmCnt > 0){
var list_num=0;
mmList.innerHTML="<p>";
pageList.innerHTML=" &nbsp;跳页: ";
for (var i=seed; i <= limit; i++){ //递增行循环结构
list_num = i + 1;
if(via.objMmInfo.selMm=="t"){
elm = "&nbsp;<input type=checkbox onClick=\"" + write_via + ".chkItemSel(" + i + ");\" checked";
elm += " title='切换是否要播放此曲目' style='cursor:hand'>";
} else {
elm = "&nbsp;<input type=checkbox onClick=\"" + write_via + ".chkItemSel(" + i + ");\"";
elm += " title='切换是否要播放此曲目' style='cursor:hand'>";
}
elm += "&nbsp;<span lang=ko>&#9836;</span>" + list_num + ". ";
elm += "<a href=\"javascript:" + write_via + ".selPlPlay(" + i + ");\"";
elm += " title='点一下播放此单一曲目'>";
if(via.objMmInfo.mmTit =="nAnT"){
elm += "未指定媒体标题(等待自动取得媒体资讯)";
} else {
elm += via.objMmInfo.mmTit;
}
elm += "</a><br>";
mmList.innerHTML=mmList.innerHTML+elm;
}
for(var j=1; j<=totBlock; j++){
page = "<a href=\"javascript:dspList(" + j + ")\">[" + j + "]<a> ";
pageList.innerHTML=pageList.innerHTML+page;
}
pageInfo.innerHTML = "页次: " + cblock + " / " + totBlock;
} else {
mmList.innerHTML = "<br><div align=center style='color:black'>播放清单上没有设定任何曲目。<br>欢迎访问<a href=http://okay100.icpcn.com>云飘过 水流过</a></div>";

}
}

修改后代码：

<s cript language="JavaScript">
<!–
var via = opener;
var write_via = "opener";
var iLoc = self.location.href;
function playSel(){via.wmpStop();via.startExobud();}
function refreshPl(){self.location=iLoc;}
function chkSel(){via.chkAllSel();refreshPl();}
function chkDesel(){via.chkAllDesel();refreshPl();}

function dspList(n){
var elmABlock = 20; // 设定每页可显示多少个播放项目
var totElm = via.intMmCnt;
var totBlock = Math.floor((via.intMmCnt-1) / elmABlock)+1;
var cblock;
if(n==null){cblock=1;} else {cblock=n;}
var seed;
var limit;
if(cblock < totBlock){
seed=totElm-1-(cblock-1)*elmABlock; limit=totElm-1-cblock*elmABlock; //控制循环的起始 999－979
} else {
seed=totElm-1-elmABlock*(totBlock-1); limit=0;
}

if(via.intMmCnt > 0){
var list_num=0;
mmList.innerHTML="<p>";
pageList.innerHTML=" &nbsp;跳页: ";
for (var i=seed; i >= limit; i–){ //递减型循环结构
list_num = i + 1;
if(via.objMmInfo.selMm=="t"){
elm = "&nbsp;<input type=checkbox onClick=\"" + write_via + ".chkItemSel(" + i + ");\" checked";
elm += " title='切换是否要播放此曲目' style='cursor:hand'>";
} else {
elm = "&nbsp;<input type=checkbox onClick=\"" + write_via + ".chkItemSel(" + i + ");\"";
elm += " title='切换是否要播放此曲目' style='cursor:hand'>";
}
elm += "&nbsp;<span lang=ko>&#9836;</span>" + list_num + ". ";
elm += "<a href=\"javascript:" + write_via + ".selPlPlay(" + i + ");\"";
elm += " title='点一下播放此单一曲目'>";
if(via.objMmInfo.mmTit =="nAnT"){
elm += "未指定媒体标题(等待自动取得媒体资讯)";
} else {
elm += via.objMmInfo.mmTit;
}
elm += "</a><br>";
mmList.innerHTML=mmList.innerHTML+elm;
}
for(var j=1; j<=totBlock; j++){
page = "<a href=\"javascript:dspList(" + j + ")\">[" + j + "]<a> ";
pageList.innerHTML=pageList.innerHTML+page;
}
pageInfo.innerHTML = "页次: " + cblock + " / " + totBlock;
} else {
mmList.innerHTML = "<br><div align=center style='color:black'>播放清单上没有设定任何曲目。<br>欢迎访问<a href=http://okay100.icpcn.com>云飘过 水流过</a></div>";
}
}

代码修改后就可以将序号大的后添加的 歌曲排到前面，简单吧！

如果大家还有不满意的，还请多加指正！！
