我正在制作记忆游戏。翻转卡时,会将类.flip添加到该卡中。我通过检查是否已经使用hasClass()方法将类.flip添加到两者中来跟踪是否已经挑选了两张相同的卡。
但是,hasClass()的jQuery似乎不起作用。我正在使用控制台日志来检查,但控制台没有打印任何东西。这是我的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");
}
});
这是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>
CSS:
.panel {
float: left;
width: 150px;
height: 150px;
margin: 20px;
position: relative;
-webkit-perspective: 600px;
-moz-perspective: 600px;

答案 0 :(得分:2)
您需要将测试类内的if
子句放在事件处理程序中。目前它是document.ready
处理程序的一部分,所以测试只在首次加载页面时发生过一次。
此外,已弃用.toggle()
的两个功能版本。
请尝试使用此功能,它似乎具有您需要的全部功能:
$(document).ready(function(){
$('.click').on('click', function() {
$(this).toggleClass('flip');
if ($('.flip').length === 2) {
console.log('yo');
}
});
});
