a.heart所以我正在尝试更改td.opened== 24 的时间。我不确定发生了什么问题，因为什么也没发生。

HTML：

<body>
<header>
<div id="headerTitle"><a href="index.html">&lt;html<span class="heart">&hearts;</span>ve&gt;</a>
            </div>
            <div id="help">
                <h2>?</h2>
                <div id="helpInfo">
                    <p>How many tiles are there? Let's see [calculating] 25...</p>

$(document).ready(function() {

那是因为$('.opened').length在您的代码中只计算一次。当您更改元素的类时，集合不会实时更新。当然，openCards 的数量不能自行改变。

代替

if (openedCards == 24){

经过

if ($('.opened').length == 24){

每次都计算它。
