少し前に、ここの人々は私をコードで非常によく助けてくれました。今、私は小さな関数を追加する任務を負っています：

ピックで定義されている当選番号を数えるのが本当に好きです。

誰かが最後の列の後ろに緑/当選番号の合計で余分な列を追加するためのコードを説明/編集できますか？

これがウェブサイトです：http：//www.coldcharlie.nl/lotto/

そしてここにコードがあります：

HTML

<script type="text/javascript" src="../lotto/lotto.js"></script>

<div id="players"></div>
<div id="draws"></div>

JavaScript

(function() {

 var players = {
    Joop   : ["6","8","16","18","26","28","32","36","38","41"],

ああ、私はこれに最後に取り組んだことを覚えています：p

更新されたbuildPlayers関数：

var buildPlayers = function(){
    var cont = $("#players"), table = $('<table></table>');
    for( player in players ){
    if ( players.hasOwnProperty( player ) ) {
        var tr = $('<tr><th>' + player + '</th></tr>').appendTo(table),
            len = players[player].length;

        for ( var i = 0; i < len; i++) {
            var td = $('<td/>') 
     td.addClass("loss")
    .addClass("pick_" + players[player][i]) // add the class to the td  
    .text( players[player][i] )
    .appendTo ( tr );

    }

    **var winning = $('<td>').addClass('winning-col').appendTo(tr);**

        cont.append( table );
    }
    }
};

更新された呼び出し：

$(function(){
    buildPlayers();
    buildDraws();
    function countWinning() {
    $('#players table tr').each(function() {
        var winning = $('td.win', this), total = 0;
        winning.each(function(i,num) {
        total+= parseInt( $(this).text(), 10);
        });
        $('.winning-col', this).text(total).css('color', 'pink');
    });
    }
    countWinning();
});

説明：基本的に、すべての行を反復処理します。各テーブル行ごとに呼び出される関数内で、すべての当選番号をカウントしてカウントし、合計を当選列の最後のテーブルセルに追加します。
