1、在織夢系統中找到以下目錄\include\taglib中的arclist.lib.php文件并打開

   大約在74 、75行找到：

// arclist是否需要weight排序,默認為"N",如果需要排序則設置為"Y"
$isweight = $ctag->GetAtt('isweight');

把這行修改為： 

$weight = $ctag->GetAtt('weight');

大約在327行找到 

//文檔排序的方式
    $ordersql = '';
    if($orderby=='hot' || $orderby=='click') $ordersql = " ORDER BY arc.click $orderWay";
    else if($orderby == 'sortrank' || $orderby=='pubdate') $ordersql = " 

ORDER BY arc.sortrank $orderWay";
    else if($orderby == 'id') $ordersql = "  ORDER BY arc.id $orderWay";
    else if($orderby == 'near') $ordersql = " ORDER BY ABS(arc.id - ".$arcid.")";
    else if($orderby == 'lastpost') $ordersql = "  ORDER BY arc.lastpost $orderWay";
    else if($orderby == 'scores') $ordersql = "  ORDER BY arc.scores $orderWay";
    else if($orderby == 'rand') $ordersql = "  ORDER BY rand()";
    else $ordersql = " ORDER BY arc.sortrank $orderWay";

修改為： 

//文檔排序的方式
    $ordersql = '';
    if($orderby=='hot' || $orderby=='click') $ordersql = " ORDER BY arc.click $orderWay";
    else if($orderby == 'sortrank' || $orderby=='pubdate') $ordersql = " 

ORDER BY arc.sortrank $orderWay";
    else if($orderby == 'id') $ordersql = "  ORDER BY arc.id $orderWay";
    else if($orderby == 'near') $ordersql = " ORDER BY ABS(arc.id - ".$arcid.")";
    else if($orderby == 'lastpost') $ordersql = "  ORDER BY arc.lastpost $orderWay";
    else if($orderby == 'scores') $ordersql = "  ORDER BY arc.scores $orderWay";
    else if($orderby == 'rand') $ordersql = "  ORDER BY rand()";
    else if($orderby == 'weight') $ordersql = "  order by arc.weight $orderWay";//如果沒有特定設置排序則按照權重先排序
    else $ordersql = " ORDER BY arc.sortrank $orderWay";

OK   現在把這個文檔保存了  我們就可以在首頁使用 orderby='weight' 進行排序了。
