jquery – AnimationEnd不工作

我正在使用AnimationEnd来触发添加新类.它在Chrome中运行良好,但其他浏览器没有响应.我不知道为什么.

JS

<script type="text/javascript">
    $(document).ready(function() {
        $('.background-image').on('webkitAnimationEnd mozAnimationEnd msAnimationEnd oAnimationEnd animationEnd', function() {
            $(this).addClass('visible');
        });
    });

</script>

CSS

@-webkit-keyframes fade-in {
  0%   { opacity: 0; }
  100% { opacity: 1; }
}
@-moz-keyframes fade-in {
  0%   { opacity: 0; }
  100% { opacity: 1; }
}
@-ms-keyframes fade-in {
  0%   { opacity: 0; }
  100% { opacity: 1; }
}
@-o-keyframes fade-in {
  0%   { opacity: 0; }
  100% { opacity: 1; }
}
@keyframes fade-in {
  0%   { opacity: 0; }
  100% { opacity: 1; }
}

.background-image {
  background: url('images/bg.jpg') no-repeat center center fixed;

  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;

  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;

  opacity: 0;

  -webkit-animation-name: fade-in;
  -webkit-animation-duration: 1s;
  -webkit-animation-timing-function: ease-in;
  -webkit-animation-iteration-count: 1;
  -webkit-animation-delay: 3s;

  -moz-animation-name: fade-in;
  -moz-animation-duration: 1s;
  -moz-animation-timing-function: ease-in;
  -moz-animation-iteration-count: 1;
  -moz-animation-delay: 3s;
}

.background-image.visible {
   opacity: 1;
}

看起来它正在绊倒mozAnimationEnd.试试这个,我在Firefox中测试过：

jsFiddle

$(document).ready(function() {
    $('.background-image').on('animationend webkitAnimationEnd oAnimationEnd', function() {
        $(this).addClass('visible');
    });
});
