将自定义动画 class 添加到 jQuery

Question

我在 CSS 中创建了一个自定义动画 class，我正在使用 jQuery 将其动态添加到元素中。我的自定义动画 class 在 animate.css 动画完成后开始。

我遇到的问题是我的自定义动画没有播放，而且我终究无法弄清楚自己做错了什么。我可以在开发工具中看到 class 正在添加到我的元素中，但动画没有发生。

自定义淡入淡出 css:

.custom-fade{
    -webkit-animation: 3s ease 0s normal forwards 1 custom;
    animation: 3s ease 0s normal forwards 1 custom;
}

@keyframes custom{
    0% { opacity:.5; }
    66% { opacity:.2; }
    100% { opacity:0; }
}

@-webkit-keyframes custom{
    0% { opacity: .5; }
    66% { opacity: .2; }
    100% { opacity: 0; }
}

@-moz-keyframes custom{
    0% { opacity: .5; }
    66% { opacity: .2; }
    100% { opacity: 0; }
}

jQuery:

var animationEnd = 'webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend';
var fadeInUp = 'animated fadeIn fadeInUp';
var fadeOut = 'animated fadeOut';
var customFade = '.custom-fade';

$('.bg-img').addClass(fadeInUp);

    $('.bg-img').one( animationEnd, function(){
        $(this).removeClass(fadeInUp).addClass('.custom-fade');
    });

问题出在添加class。你应该在 addClass().

中给出 'custom-fade' 而不是 '.custom-fade'

示例代码：

jQuery:

var animationEnd = 'webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend';
var fadeInUp = 'animated fadeIn fadeInUp';
var fadeOut = 'animated fadeOut';
var customFade = '.custom-fade';

$('.bg-img').addClass(fadeInUp);

    $('.bg-img').on( animationEnd, function(){
        $(this).removeClass(fadeInUp).addClass('custom-fade');
    });

.custom-fade{
    -webkit-animation: 3s ease 0s normal forwards 1 custom;
    animation: 3s ease 0s normal forwards 1 custom;
}

@keyframes custom{
    0% { opacity:.5; }
    66% { opacity:.2; }
    100% { opacity:0; }
}

@-webkit-keyframes custom{
    0% { opacity: .5; }
    66% { opacity: .2; }
    100% { opacity: 0; }
}

@-moz-keyframes custom{
    0% { opacity: .5; }
    66% { opacity: .2; }
    100% { opacity: 0; }
}
.bg-img{
width:200px;
height:500px;
background:red;
}
