javascript代码不再改变字体颜色答案

【问题标题】：javascript code doesn't change font color anymorejavascript代码不再改变字体颜色

【问题描述】：

有人为我编写了一个不错的代码，但在对表格中的输出进行了一些更改后，array picks 字体不再更改，由以下 CSS 控制。

.win { color: lime; font-weight: bold }

.loss { color: red; font-weight: bold }

有人可以帮我编辑代码，使 数组选择 在获胜或没有获胜时再次变为石灰和红色吗？

【问题讨论】：

我认为您缺少指向 jquery.js 的链接。
我猜这可能发生在 lotto.js 中，但谁知道..
确实如此安德烈，我复制粘贴它，因为jquery服务器有时很慢。

【解决方案1】：

当您更改为您的表格布局时，您设法失去了根据需要添加“赢”或“输”类别的类别。相关代码为：

var showWin = function(winNum){
    $(".pick_"+winNum).removeClass("loss").addClass("win");
};

它无法找到具有“pick_[some number]”类的元素，然后它无法添加赢或输类别，并且您无法获得颜色。

要解决您的问题，在 BuildPlayers 函数中，您需要以下内容：

var td = $('<td/>').text(players[player][i]);
td.addClass("pick_" + players[player][i]);
td.appendTo(tr);

这可以合并为一行，但我认为这样可能更容易看到。中间线（“addClass”）是您所缺少的。

【讨论】：

我对这些答案有点困惑，我需要替换或添加什么？
感谢您的回复，唯一的问题是.loss没有显示，我的知识没有涵盖这个问题。
克里斯，只需将 loss 类也添加到 td 中。在将 td 附加到 tr 之前，添加 td.addClass("loss");

【解决方案2】：

改变

for ( var i = 0; i < len; i++) {
        var td = $('<td/>').text( players[player][i] )
        .appendTo ( tr );
    }

收件人：

for ( var i = 0; i < len; i++) {
        $(tr).append( "<td><span class='pick_" + players[player][i] +"'>" + players[player][i] + "</span></td>");
    }

您忘记在数字中添加正确的类。

【讨论】：

【解决方案3】：

加布里埃尔是正确的。在buildPlayers函数中创建td的地方需要添加pick_#类。

把这个放在for循环里面：

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

应该解决问题。

+1 是的，就是这样……我不想通读所有代码来早点找到那行……哈哈。
