我正在制作一个记忆游戏。当卡片翻转时,会将类 .flip 添加到该卡片。我通过使用 hasClass() 方法来跟踪两张相同的卡片是否已被选择,检查是否已将类 .flip 添加到两张卡片上。
然而,hasClass() 的 jQuery 代码似乎无法正常工作。我使用控制台日志进行检查,但控制台没有打印任何内容。以下是我的 jQuery 代码:

$(document).ready(function(){
var counter = 0;
if(counter == 0){
console.log(counter);
// set up click/tap panels
$('.click').toggle(function(){
counter = 1;
console.log(counter);
$(this).addClass('flip');
},function(){
/*$(this).removeClass('flip');*/
});
}
if($("#heart-01").hasClass("flip") && $("#heart-02").hasClass("flip")){
console.log("yo");
}
});
Here's the HTML:
<div id="heart-01" class="panel click heart">
<div class="front"></div>
<div class="back"></div>
</div>
<div id="heart-02" class="panel click heart">
<div class="front"></div>
<div class="back"></div>
</div>
以下是相关的CSS代码:

调用的代码行,他应该已经看到了value = 1的价值。 - David TanseyaddClass
调用,但是hasClass
测试不在事件处理程序内,它们在页面加载时调用,在addClass
调用被触发之前。 - Alnitak
